    E- learning: B.Sc. Part-II, Botany Hons and Part-I Sub.] Biological Nitrogen Fixation Dr. Anuj Rani, Department of Botany, T.N.B. College, Bhagalpur Email: [email protected] Conversion of molecular nitrogen (N2) of the atmosphere into inorganic nitrogenous compounds such as nitrates or ammonia is called as nitrogen fixation. When this nitrogen fixation occurs through the agency of some living organisms, the process is called as biological nitrogen fixation in which atmospheric nitrogen is converted into ammonia. Not all the organisms have capacity to fix molecular nitrogen (N2) of the atmosphere. Only certain prokaryotic micro-organisms such as some free living bacteria, cyanobacteria (blue- green algae) and some of the prokaryotic micro- organisms in symbiotic association with other plants (mostly legumes) can fix atmospheric nitrogen. They can be grouped as follows: A. Free Living: 1. Autotrophic: (a) Aerobic e.g., some cyanobacteria (blue-green algae). All those blue-green algae which can fix atmospheric nitrogen usually contain heterocyst’s such as Nostoc, Anabaena, Tolypothrix, Aulosira, Calothrix etc. But all the heterocyst’s bearing blue-green algae may not be atm. nitrogen fixers. A few non- heterocystous blue-green algae such as Gloeotheca are also known to fix atm. N2. (b) Anaerobic e.g., certain bacteria such as Chromatium and Rhodospirillum. 2. Heterotrophic: (a) Aerobic e.g., certain bacteria such as Azotobacter, Azospirillum, Derxia and Beijerinckia. (b) Facultative e.g., certain bacteria such as Bacillus and Klebsiella. (c) Anaerobic e.g., certain bacteria such as Clostridium and Methanococcus. 1 B. Symbiotic: (a) Root Nodules of Leguminous Plants: Various types of bacteria called rhizobia associated with root nodules of legumes can fix atm.

    ISSN: 0975-8585 Research Journal of Pharmaceutical, Biological and Chemical Sciences A Novel Approach to Enhancement of Poly-Β-Hydroxybutyrate Accumulation Aulosira Fertilissima by Mixotrophy And Chemohetertrophy. 1S Sirohi*, 2N Mallick, 3SPS Sirohi , 1PK Tyagi, and 1GD Tripathi. 1Department of Biotechnology, MIET Meerut-250005, India. 2Department of Agricultural and Food Engineering, IIT Kharagpur-721302, India. 3Kisan PG Collage Simbhaoli, Gaziabad, India. ABSTRACT Aulisira fertilissima, a unicellular cyanobacterium, produced poly-β-hydroxybutyrate (PHB) up to 5.4% (w/w) dry cells when grown photoautotrophically but 8.9% when grown mixotrophically with 0.2% (w/v) glucose and acetate after 24 days. Gas-exchange limitations under mixotrophy and chemoheterotrophy with 0.2% (w/v) acetate and glucose enhanced the accumulation up to 17–19% (w/w) dry cells, the value almost 4- fold higher with respect to photoautotrophic condition. These results revealed high potential of Aulisira fertilissima in accumulating PHB, an appropriate raw material for biodegradable and biocompatible plastic. PHB could be an important material for plastic and pharmaceutical industries. Keywords: chemoheterotrophy, mixotrophy, Aulosira fertilissima, poly-β-hydroxybutyrate *Corresponding author March – April 2015 RJPBCS 6(2) Page No. 1266 ISSN: 0975-8585 INTRODUCTION Infact, Polyhydroxyalkanoates (PHAs) are the polymers of hydroxyalkanoates, which has gained tremendous impetus in the recent years because of its biodegradable and biocompatible nature and can be produced from renewable sources. PHAs are accumulated as a carbon and energy storage material in various microorganisms usually under the condition of limiting nutritional elements such as N, P, S, O, or Mg [1] in the presence of excess carbon [2]. Many of these bacterial species produce the polymer up to 20% of the dry cell weight (dcw) and a few, such as, Ralstonia eutropha, now called as Wautersia eutropha, is capable of accumulating poly-β-hydroxybutyrate (PHB) up to almost 80% of the dcw [3].

Accepted: June 24, 2019 Data deposition: This project has been deposited at NCBI BioProject under the accession PRJNA534312. Abstract Plant endosymbiosis with nitrogen-fixing cyanobacteria has independently evolved in diverse plant lineages, offering a unique window to study the evolution and genetics of plant–microbe interaction. However, very few complete genomes exist for plant cyanobionts, and therefore little is known about their genomic and functional diversity. Here, we present four complete genomes of cyanobacteria isolated from bryophytes. Nanopore long-read sequencing allowed us to obtain circular contigs for all the main chromosomes and most of the plasmids. We found that despite having a low 16S rRNA sequence divergence, the four isolates exhibit considerable genome reorganizations and variation in gene content. Furthermore, three of the four isolates possess genes encoding vanadium (V)-nitrogenase (vnf), which is uncommon among diazotrophs and has not been previously reported in plant cyanobionts. In two cases, the vnf genes were found on plasmids, implying possible plasmid-mediated horizontal gene transfers. Comparative genomic analysis of vnf-contain- ing cyanobacteria further identified a conserved gene cluster.

College Teonthar, M.P , India ABSTRACT The cyanobacteria are an ancient group of prokaryotic organisms that are found all over the world in environments as diverse as Antarctic soils and volcanic hot springs, and often where no other vegetation can exist. Being prokaryotes they share with others of their type the lack of a nucleus and a laminated extracellular wall. Unlike photosynthetic bacteria however, cyanobacteria possess chlorophyll - a in common with photosynthetic eukaryotes, and they liberate oxygen during photosynthesis. Cyanobacteria are ubiquitous in waters of a great range of salinity and temperature, and they occur in and on the soil as well as on rocks and i n their fissures. As well, they form symbiotic and commensal relationships with a number of other organisms. In general, they are most abundant from waters with a neutral or slightly alkaline pH and can exhibit diurnal variation in abundance in waters with low buffering capacity .

Edited by Siew-Moi Phang,Khanjanapaj Lewmanomont and Phaik-Eem Lim. Institute of Ocean and Earth Sciences (IOES),University of Malaya, Monograph Series 2. 197 p., soft- or hardcover [http://ioes.um.edu.my; ISBN: 978-967-5148-13-2; Price: RM 80 (soft cover), RM 100 (hard cover)]. The central Indo-Pacific harbours one of the most diverse seaweed floras on Earth, yet the taxonomy of marine macro-algae in these tropical to subtropical waters has remained relatively poorly studied. With this volume, three leading algal systematists in the region,Siew-Moi Phang,Khanjanapaj Lewmanomont and Phaik-Eem Lim, are providing an important outlet for taxonomic knowledge of Southeast Asian seaweeds. The book represents the proceedings of the First Taxonomy of Southeast Asian Seaweed Workshop held at the University of Malaya, Kuala Lumpur in 2008. This workshop, the first in a series to come, brought together phycologists from different countries and was intended to “keep the science of taxonomy and systematics flourishing and ensure the existence of a next generation of seaweed taxonomists in the Southeast Asian region”. The present volume contains a collection of twelve scientific contribu- tions from a long list of authors, all active researchers in seaweed biology in Southeast Asia. In particular seaweeds of Thailand, Malaysia, Indonesia, and to a lesser extent Vietnam and the South China Sea, are represented in this volume. Somewhat surprisingly, the Philippines, a country with a rich seaweed flora and a long history of phycology is only poorly represented.

R. (2014): Taxonomic classification of cyanoprokaryotes (cyanobacterial genera) 2014, using a polyphasic approach. – Preslia 86: 295–335. The whole classification of cyanobacteria (species, genera, families, orders) has undergone exten- sive restructuring and revision in recent years with the advent of phylogenetic analyses based on molecular sequence data. Several recent revisionary and monographic works initiated a revision and it is anticipated there will be further changes in the future. However, with the completion of the monographic series on the Cyanobacteria in Süsswasserflora von Mitteleuropa, and the recent flurry of taxonomic papers describing new genera, it seems expedient that a summary of the modern taxonomic system for cyanobacteria should be published. In this review, we present the status of all currently used families of cyanobacteria, review the results of molecular taxonomic studies, descriptions and characteristics of new orders and new families and the elevation of a few subfamilies to family level.

  • A Checklist and Distributional Analysis of Marine Algal Species Collected As Vouchers During the CHIA-EVOS Studies
    A checklist and distributional analysis of marine algal species collected as vouchers during the CHIA-EVOS studies. (submitted under BAA) Project Number: Restoration Category: Research and publication preparation Proposer: Gayle I. Hansen (Oregon State University, HMSC) Lead Trustee Agency: Cooperating Agencies: Alaska SeaLife Center: No Duration: 1st year of a 1-year project Cost FY 01: $65,734 Geographic Area: No field work will be carried out, but specimens from the entire oil spill area will be utilized for the study. Injured Resource/Service: Intertidal communities: macrobenthic marine algae or seaweeds. ABSTRACT During the CHIA-EVOS studies, intense investigations were carried out on the intertidal algal communities of Prince William Sound, Kenai, Kodiak, and the Alaska Peninsula. As a byproduct of these studies, thorough voucher collections were made of the algal species present in more than 100 transect areas used for the study. The 7,300 voucher specimens were identified to species, curated, and cataloged, but no money was available at the time for publishing the wealth of information on algal biodiversity and distribution they provided. For this study, we will use these data to prepare regional checklists and biogeographic analyses of the species discovered and finally make available these critical habitat data for restoration and conservation efforts in Alaska. Prepared 06/07/2005 1 Project ______ INTRODUCTION Macrobenthic marine algae or seaweeds form the base of the food chain in nearly all rocky intertidal and shallow subtidal communities. In areas where they flourish, they also benefit both the structural and chemical environment. Nearshore marine animals are all at least partially dependent on algae for survival, and the environmental stresses that impact the algae also impact these members of the higher trophic levels.
