The event will featur several parallel sessions, talks, discussions, poster sessions, and guided field trips. The Symposium program is in line with THE SUSTAINABLE DEVELOPMENT AGENDA, the major goal of the UNITED NATIONS (UN), adopted in the 70/1 Resolution by the General Assembly of the UN in September 2015. In this edition, at the Pontifical Catholic University of Rio Grande do Sul (henceforth PUCRS), the motto is Facing human impacts: the challenges for society and for science. 217 scientific papers on topics such as Ocean, Agriculture and Food Safety, Water, Resource Management, Global Climate Change, Biodiversity, Ecology, and Forestry, Bioeconomy, Green Infrastructure in Urban Areas, Global Geoparks, Social and Environmental Responsibility, Public Health and Environmental Law and Ethics were presented. Additionally, the session on Binational Programs and Cooperation gives an overview e different binational programs and cooperation opportunities between Germany and Brazil. The engagement of over 670 authors shows academic dedication within these areas and the motivation for scientific exchange between Germans and Brazilians, supported by public and private institutions. The biannual editions of the Symposium, promoted alternatively in Germany and Brazil have created the opportunity to include scientific novels and the participation of prominent researchers, which, alongside young researchers and students devoted to building knowledge in search for answers, strengthen the system with every new edition of this Symposium. These Abstracts contain submitted and approved works for the Symposium and are organized in sequence according to its 14 sessions. At the end, the reader can find an author index. 2 Finally, we are grateful for the opportunity to host this edition of the Symposium at PUCRS, where our scientific community has embraced this opportunity with its strong engagement, along with German, Brazilian and other international institutions. The structure of this 8th edition of the Symposium will mirror the previous editions, stemming from the close collaboration between the German and Brazilian organizing committees. The support from public and private institutions was essential to make this event possible, and with that in mind, we would like to show our gratitude to CAPES. We wish all participants and guests a fruitful experience by the Symposium and a pleasant time in Porto Alegre.

The first Symposium was held in Tübingen, Germany. The purpose of the Symposium is to present and discuss the differences and similarities regarding the sustainable development of two societies in terms of their cultural identity with natural resources and its processes. The 2017 edition will be hosted at the Pontifical Catholic University of Rio Grande do Sul, in Porto Alegre, RS, Brazil. The theme of this edition will be “Facing human impacts: the challenges for society and for science”. In this event, the scientific exchange between colleagues from Brazil and Germany in the field of technological innovation and sustainability comes in handy. The focus is mainly on issues related to energy, water, soil, climate, biodiversity, agriculture and forestry, politics, economics, resource management and future cities. The sustainable development agenda Since September 25th, 2015, Sustainability has been a major issue in the UNITED NATIONS agenda (Fig.1). This goal is called the agenda 2030 and was adopted as the Resolution 70/1 by the General Assembly of the UNITED NATIONS. Fig. 1: Sustainable development goals (http://nacoesunidas.org/pos2015/agenda2030/) 5 70/1. Transforming our world: the 2030 Agenda for Sustainable Development “The General Assembly adopts the following outcome document of the United Nations summit for the adoption of the post-2015 development agenda: Transforming our world: the 2030 Agenda for Sustainable Development”. Preamble “This Agenda is a plan of action for people, planet and prosperity. It also seeks to strengthen universal peace in larger freedom. We recognize that eradicating poverty in all its forms and dimensions, including extreme poverty, is the greatest global challenge and an essential demand for sustainable development. All countries and all stakeholders, acting in collaborative partnership, will be required to implement this plan. We are resolved to free the human race from the tyranny of poverty and want and to heal and secure our planet. We are determined to take the bold and transformative steps which are urgently needed to move the world towards a sustainable and resilient direction. As we embark on this collective journey, we pledge that no one will be left behind. The 17 Sustainable Development Goals and 169 targets which we are announcing today demonstrate the scale and ambition of this new universal Agenda. They seek to build on the Millennium Development Goals and complete what they failed to achieve. They seek to realize the human rights of all and to achieve gender equality and the empowerment of all women and girls. They are integrated and indivisible and incorporate the three dimensions of sustainable development: the economic, social and environmental. The Goals and targets will foster actions over the next fifteen years in areas of critical

Extremophile microorganisms are found in several extreme marine environments, such as hydrothermal vents, hot springs, salty lakes and deep-sea floors. The ability of these microorganisms to support extremes of temperature, salinity and pressure demonstrates their great potential for biotechnological processes. Hydrolases including amylases, cellulases, peptidases and lipases from hyperthermophiles, psychrophiles, halophiles and piezophiles have been investigated for these reasons.

During the experiment, 58 microbial isolates (43 epiphytes and 15 endophytes) with different morphologies were obtained. We successfully identified 85% of microorganisms and assigned them to 9 bacterial genera: Achromobacter, Bacillus, Microbacterium, Delftia, Agrobacterium, and Alcaligenes (epiphytes) as well as Bacillus, Staphylococcus, Micrococcus, and Acinetobacter (endophytes). We also studied an A. filiculoides cyanobiont originally classified as Anabaena azollae; however, the analysis of its morphological traits suggests that this should be renamed as Trichormus azollae. Finally, the potential of the representatives of the identified microbial genera to synthesize plant growth-promoting substances such as indole-3-acetic acid (IAA), cellulase and protease enzymes, siderophores and phosphorus (P) and their potential of utilization thereof were checked. Delftia sp. AzoEpi7 was the only one from all the identified genera exhibiting the ability to synthesize all the studied growth promoters; thus, it was recommended as the most beneficial bacteria in the studied microbiome.

  • Extreme Environments and High-Level Bacterial Tellurite Resistance
    microorganisms Review Extreme Environments and High-Level Bacterial Tellurite Resistance Chris Maltman 1,* and Vladimir Yurkov 2 1 Department of Biology, Slippery Rock University, Slippery Rock, PA 16001, USA 2 Department of Microbiology, University of Manitoba, Winnipeg, MB R3T 2N2, Canada; [email protected] * Correspondence: [email protected]; Tel.: +724-738-4963 Received: 28 October 2019; Accepted: 20 November 2019; Published: 22 November 2019 Abstract: Bacteria have long been known to possess resistance to the highly toxic oxyanion tellurite, most commonly though reduction to elemental tellurium. However, the majority of research has focused on the impact of this compound on microbes, namely E. coli, which have a very low level of resistance. Very little has been done regarding bacteria on the other end of the spectrum, with three to four orders of magnitude greater resistance than E. coli. With more focus on ecologically-friendly methods of pollutant removal, the use of bacteria for tellurite remediation, and possibly recovery, further highlights the importance of better understanding the effect on microbes, and approaches for resistance/reduction. The goal of this review is to compile current research on bacterial tellurite resistance, with a focus on high-level resistance by bacteria inhabiting extreme environments. Keywords: tellurite; tellurite resistance; extreme environments; metalloids; bioremediation; biometallurgy 1. Introduction Microorganisms possess a wide range of extraordinary abilities, from the production of bioactive molecules [1] to resistance to and transformation of highly toxic compounds [2–5]. Of great interest are bacteria which can convert the deleterious oxyanion tellurite to elemental tellurium (Te) through reduction. Currently, research into bacterial interactions with tellurite has been lagging behind investigation of the oxyanions of other metals such as nickel (Ni), molybdenum (Mo), tungsten (W), iron (Fe), and cobalt (Co).

  • ABSTRACT OZDEMIR, INCI. Role of S-Layer Homology Domain
    ABSTRACT OZDEMIR, INCI. Role of S-layer Homology Domain Proteins in Plant Biomass Conversion to Biofuels by Extremely Thermophilic Caldicellulosiruptor species. (Under the direction of Robert M. Kelly.) Second-generation biofuels require the conversion of lignocellulose from agricultural waste, non-edible parts of crops, and grasses into fermentable sugars. Lignocellulose is composed of pectin, hemicellulose, cellulose and lignin, all of which form a matrix that must be penetrated and deconstructed by physical, chemical and biological methods to facilitate conversion to biofuels. Certain microorganisms have the capacity to extract the carbohydrate content of lignocellulose through the coordinated action of glycoside hydrolases and other metabolic processes, which together can contribute to biofuel production. Of interest here are extremely thermophilic bacteria from the genus Caldicellulosiruptor. One of the intriguing features of these bacteria is that they do not produce cellulosomes but rather produce multi-domain (hemi)cellulolytic enzymes. Some of these biocatalysts contain S-layer homology (SLH) domains, anchoring the enzymes to the cell envelope, and also have carbohydrate-binding domains (CBM), which bind the enzyme to the substrate. This can be a very efficient way of degrading plant biomass since enzymes are localized in close proximity of the cell where control its local microenvironment is possible. Six different groups of SLH-domain proteins with GH domains could be identified in the genome sequences of Caldicellulosiruptor species. Representatives from each group were produced recombinantly in E. coli and examined with respect to biochemical and biophysical properties. Csac_0678 (bifunctional cellulase/xylanase from C. saccharolyticus with homologs in all eight genome- sequenced Caldicellulosiruptor species), Calkr_2245 (xylanase from C.

    Development of ferruginous duricrusts (canga) in tropical iron ore systems Alan Levett B.Sc. H. Majoring in Geological Sciences (UQ) 2014 B.Sc. Extended Major in Biomedical Sciences (UQ) 2011 A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland – 2020 School of Earth and Environmental Sciences Abstract Iron-rich duricrusts (canga) that cap iron ore deposits in Brazil evolve by the redox-based cycling of iron oxide minerals, continually forming new iron-rich cements that effectively prevent the physical erosion of these landforms. This thesis aimed to understand the biological influences on the geochemical cycling of iron within canga, to determine if these processes could be used to accelerate iron cement formation, for example, in a post-mining context. Re- cementing waste material (canga) from iron ore mining may provide an environmentally- friendly solution for iron ore mine remediation in Brazil and the restoration of a rare ecosystem associated with canga outcrops. Field emission scanning electron microscopy revealed an array of microorganisms fossilised within canga, highlighting the innate role of microorganisms in the evolution of canga horizons. Nanoscale elemental mapping of these microfossils revealed a role for aluminium in the long-term preservation of organic and inorganic biosignatures. A suite of high-resolution analytical techniques were correlated to understand the fossilisation processes that contribute to biosignature preservation in near-neutral iron-rich environments. Further investigation of the microfossils in canga, revealed the complex weathering patterns induced by microorganisms. Grains within canga could be completely weathered and texturally replaced by microfossils; only remnants of the grain’s shape and traces of most immobile elements (for example, thorium) were left behind.
