Considering the priorities of food security and enhancing the productivity, profitability and sustainable rural livelihoods at farm level, developing new order of farm inputs has become imperative. In this perspective, bio-inputs either directly in the form of microbes or their by-products are gaining tremendous momentum. Asian countries have a rich microbial biodiversity. Harnessing this biodiversity to identify agriculturally important microorganisms and deploy them as bio-inoculants could help in providing low-cost and environmentally safe technologies to the farmers especially those who cannot afford expensive technologies. Considering these needs of Asian nations, 10 thematic technical sessions have been planned. In these 10 sessions, detailed deliberations through exchange of International as well as Asian experiences would lead to a better understanding of interaction between climate processes and biological diversity and thereby forming important research topics for addressing the issues in overall food security. A bouquet of lead lectures, invited papers and posters provides a platform for pioneers as well as youngsters for a thread-bare discussion. The core scientific committee and agricultural scientists of international repute have identified lead as well as invited speakers. The Congress has received tremendous support from governmental and non-governmental agencies such as ICRISAT, ICAR, DST, DBT and many private companies who have already pledged their support to ‘green technologies’. Acharya N.G. Ranga Agricultural University has readily agreed to host this mega event and under the leadership of Hon’ble Vice Chancellor Dr. P. Raghava Reddy, all care has been taken for the smooth steering of the Congress. The Director of Research, ANGRAU, Dean Agriculture, Director of Extension and other senior officials of the ANGRAU have significantly provided their might in organizing this congress. We are sure, all the delegates will have a fruitful stay in Hyderabad and get the best out of this maiden effort. We hope that this abstract book will be useful as a reference manual for the participants as well as other PGPR researchers of the Globe. S. Desai M.S. Reddy Y.R. Sarma V. Krishna Rao B. Chenchu Reddy K.R.K. Reddy Inaugural speech by Dr. J. W. Kloepper Good morning. It’s a great pleasure for me to greet all of you here attending the 1st Asian PGPR congress for sustainable agriculture. Some of you in attendance here were present at the International PGPR workshop in Calicut in 2003. However, for the majority of you, this is, likely your 1st International congress centered on the theme of PGPR. Therefore, I would like to explain briefly the significance of this area. The concept of PGPR encompasses bacteria that function as biofungicides and biofertilizers. Worldwide R & D with PGPR has continually grown since the 1970s when the term PGPR was first introduced. Research with PGPR ranges from discovery of new strains and confirmation in field studies to basic molecular characterization of the strains. Hence, the study of PGPR is one area of science where both basic and applied research is essential to reach our goal of implementing the science in everyday life. And regarding implementation, every year, the use of PGPR in agriculture worldwide is increasing. As you will see during this congress, there are different models for extending the theories of PGPR to farmers depending on the social, political and regulatory policies of each country. As PGPR use was, we learned more about their current opportunities and challenges. Opportunities include alternating applications of PGPR biofungicides with chemical fungicides to manage fungicide resistance and to reduce the number of fungicide treatments per year. PGPR biofertilizers are showing promise in integrated nutrient management strategies with a goal of reducing run-off of unused fertilizers and the environmental damage that results. Throughout the world, there is a growing number of so called dead zones in oceans and seas that result from run-off of agricultural fertilizers into rivers and ultimately oceans. I very much believe that the goal of reducing fertilizer use will be to the 21st century what (while) reducing fertilizer use was to the 20th century. I am very much pleased that Dr. M. S. Reddy and the other organizers of this congress have developed a PGPR meeting specifically aimed at Asia. While the core underlying science of plant microbial interactions is global, applications in agriculture are somewhat region specific. For example, here in North America, we have no agriculture system similar to plantation crops. Hence, logically, the opportunities and challenges for using PGPR in a plantation crop system need to be addressed in the Asian region. Also, Asia has been a leader in studies of PGPR as biofertilizer which is I mentioned as a growing area of interest worldwide. I would specially like to welcome all the students and young investigators to this congress. Every year, the study of PGPR is enriched by a new crop of investigators who launch their careers working on PGPR. We all need to encourage the students and new investigators to persevere in this critically important field of science. Finally, allow me to say that I am very impressed with the organization of this congress. The entire organizing, planning and funding teams have done a simply outstanding job. I wish you all a very successful congress. Thank You (J. W. Kloepper) I Scope and Potential of First Asian PGPR Congress for Sustainable Agriculture M. S. Reddy1, K. Vijay Krishna Kumar1, H.

M. S. Reddy email: [email protected] Distinguished guests, ladies and gentlemen, it is indeed an honour for us to be here with you as a speaker in presence of the Sri Raghuveera Reddy garu, Hon’ble Minister for Agriculture, Agriculture Technology Mission, Horticulture, Sericulture, R.S.A.D., Hon’ble Vice Chancellor and host, Dr. Raghava Reddy and other distinguished guests, Asian PGPR board members and many other scientists and entrepreneurs who have come to participate in this Congress. It is our very proud privilege in welcoming all our distinguished dignitaries, speakers, delegates, members of the press and media. The idea of having the First Asian PGPR Congress in Hyderabad was brought-out by Dr. Y. R. Sarma, when he visited me in Auburn, USA, 7 months ago. Then we have discussed in length and agreed to have an alternative workshops or Congresses other than the International Workshops. Because, not many who are interested in PGPR research could attend every International Conferences due to budget constraints, this plan started to organize this Congress in Hyderabad. Dr. Raghava Reddy, Vice Chancellor of ANGARU kindly agreed to host the Congress. What is PPGR? Why Asian PGPR? Let us explain briefly about PGPR and its importance. Plant growth promoting rhizobacteria (PGPR) are root associated bacteria representing many different genera and species that colonize the rhizosphere, rhizoplane and improve plant growth when artificially introduced onto seeds, seedpieces, roots, or into soil. PGPR improve plant growth by one or more mechanisms: direct stimulation of plant growth; enhancement of nutrient uptake; suppression of

The strain of A. bogorensis used was isolated from spoiled commercial fruit-flavored drinking water. The cranberry juice was analyzed for polyphenols, organic acids, and carbohydrates using high-performance liquid chromatography and liquid chromatography–mass spectrometry techniques. The adhesive abilities of bacterial cells in culture medium supplemented with cranberry juice were determined using luminometry and microscopy. The viability of adhered and planktonic bacterial cells was determined by the plate count method, and the relative adhesion coefficient was calculated. This strain of A. bogorensis was characterized by strong adhesion properties that were dependent upon the type of surface. The highest level of cell adhesion was found on the polystyrene. However, in the presence of 10% cranberry juice, attachment of bacterial cells was three times lower. Chemical analysis of juice revealed the presence of sugars, organic acids, and anthocyanins, which were identified as galactosides, glucosides, and arabinosides of cyanidin and peonidin.

  • Anti-Adhesion Activity of Mint (Mentha Piperita L.) Leaves Extract Against Beverage Spoilage Bacteria Asaia Spp
    Biotechnology and Food Sciences Research article Anti-adhesion activity of mint (Mentha piperita L.) leaves extract against beverage spoilage bacteria Asaia spp. Hubert Antolak,* Agata Czyżowska, Dorota Kręgiel Institute of Fermentation Technology and Microbiology, Lodz University of Technology, Wolczanska 171/173, 90-924 Lodz, Poland *[email protected] Abstract: The production of a functional beverage, supplemented with fruit flavourings meets the problem of microbiological contamination. The most frequent source of such spoilage is the bacteria from the relatively newly discovered genus Asaia. It causes changes in organoleptic properties, creating turbidity, haziness and distinctive sour odour as well as biofilm on production lines which are responsible for secondary contamination of products. For this reason, new methods using natural preservatives are being developed to minimize this microbiological contamination. The application of some plant extracts as an additives in functional beverages production is presumed to have a beneficial effect on reducing adhesive abilities of the bacteria. The aim of this research was to investigate the effects of mint leaves extract on the Asaia lannensis and Asaia bogorensis adhesive abilities to polystyrene. The bacterial adhesion was analysed by means of plate count method and luminometric tests. Additionally, plant extract was subjected to high performance liquid chromatography (HPLC) analysis, in order to check polyphenols content. Results indicates that 10% (v/v) addition of mint extract significantly reduced Asaia spp. adhesion to polystyrene. Due to the presence of bioactive compounds in the used extract, it can be used as an additive to increase microbiological stability as well as health promoting values of beverages. Keywords: Asaia spp., mint extract, anti-adhesive properties, functional beverages.

Their close association with multiple organs and tissues of their mosquito hosts enhances the potential for paratransgenesis for the delivery of antimalaria or antivirus effectors. The molecular mechanisms involved in the interactions between Asaia and mosquito hosts, as well as Asaia and other bacterial members of the mosquito microbiome, remain underexplored. Here, we determined the genome sequence of Asaia strain W12 isolated from Anopheles stephensi mosquitoes, compared it to other Asaia species associated Citation: Chen, S.; Yu, T.; Terrapon, with plants or insects, and investigated the properties of the bacteria relevant to their symbiosis N.; Henrissat, B.; Walker, E.D.

The isolation of H2 producing bacteria from heat treated sludge was carried out. The H2 production from lactic acid rich medium which used 1.5 g/L sodium acetate, 1.5 g/L sodium lactate and 1 g/L sucrose as carbon sources. The effects of inoculums size of 10, 20, 30 and 40 % (v/v) and incubation temperature of 35, 45 and 55ºC using cassava starch wastewater as the substrate on H2 production by isolation strains were investigated. Results showed 6 isolated strains i.e. isolation code of MK01to MK06 indicated the H2 production capability when cultured in lactic acid rich medium. However, 3 isolated strains i.e. MK01, MK04, and MK06 were preferred to use as seed inoculums for further experiments depend on a high H2 production capacity obtained. Results indicated that the optimal condition of H2 production from cassava starch wastewater was 30% (v/v) inoculum size of MK06 under 35ºC of incubation temperature.

  • Biofilms in Beverage Industry
    Chapter 9 Biofilms in Beverage Industry Dorota Kregiel and Hubert Antolak Additional information is available at the end of the chapter http://dx.doi.org/10.5772/62940 Abstract Over the years, numerous studies have been conducted into the possible links between biofilms in beverage industry and health safety. Consumers trust that the soft drinks they buy are safe and their quality is guaranteed. This chapter provides an overview of available scientific knowledge and cites numerous studies on various aspects of biofilms in drinking water technology and soft drinks industry and their implications for health safety. Particular attention is given to Proteobacteria, including two different genera: Aeromo‐ nas, which represents Gammaproteobacteria, and Asaia, a member of Alphaproteobacteria. Keywords: biofilms, water, soft drinks, Aeromonas , Asaia 1. Drinking water systems In water systems, both natural and industrial dominate Proteobacteria. This is the main group (phylum) of Gram-negative bacteria, taxonomically very diverse, consisting of more than 200 genera. Its membership includes both pathogenic bacteria of the genera Escherichia, Salmonel‐ la, Vibrio, Helicobacter, and many other types of free-living or symbiotic, motile or nonmotile, chemoautotrophic or heterotrophic bacteria from outstanding aerobes to obligatory anaerobes. Although bacteria are physiologically and morphologically diverse, they constitute a coher‐ ent set of six main classes: Alphaproteobacteria, Betaproteobacteria, Gammaproteobacteria, Deltaproteobacteria, Epsilonproteobacteria, and Zetaproteobacteria. Taxonomy of the group is determined primarily on the basis of ribosomal RNA sequences [1]. Species belonging to the classes Alphaproteobacteria, Betaproteobacteria, and Gammaproteobacteria are very heterogene‐ ous in their physiological characteristics. Each of the three classes includes aerobes and anaerobes, photosynthetic and nonphotosynthetic cells.
