Kaistella Soli Sp. Nov., Isolated from Oil-Contaminated Soil
A001 Kaistella soli sp. nov., Isolated from Oil-contaminated Soil Dhiraj Kumar Chaudhary1, Ram Hari Dahal2, Dong-Uk Kim3, and Yongseok Hong1* 1Department of Environmental Engineering, Korea University Sejong Campus, 2Department of Microbiology, School of Medicine, Kyungpook National University, 3Department of Biological Science, College of Science and Engineering, Sangji University A light yellow-colored, rod-shaped bacterial strain DKR-2T was isolated from oil-contaminated experimental soil. The strain was Gram-stain-negative, catalase and oxidase positive, and grew at temperature 10–35°C, at pH 6.0– 9.0, and at 0–1.5% (w/v) NaCl concentration. The phylogenetic analysis and 16S rRNA gene sequence analysis suggested that the strain DKR-2T was affiliated to the genus Kaistella, with the closest species being Kaistella haifensis H38T (97.6% sequence similarity). The chemotaxonomic profiles revealed the presence of phosphatidylethanolamine as the principal polar lipids;iso-C15:0, antiso-C15:0, and summed feature 9 (iso-C17:1 9c and/or C16:0 10-methyl) as the main fatty acids; and menaquinone-6 as a major menaquinone. The DNA G + C content was 39.5%. In addition, the average nucleotide identity (ANIu) and in silico DNA–DNA hybridization (dDDH) relatedness values between strain DKR-2T and phylogenically closest members were below the threshold values for species delineation. The polyphasic taxonomic features illustrated in this study clearly implied that strain DKR-2T represents a novel species in the genus Kaistella, for which the name Kaistella soli sp. nov. is proposed with the type strain DKR-2T (= KACC 22070T = NBRC 114725T).

Eric Moody: You're Listening to Making Waves, Fresh Ideas in Freshwater Science
Eric Moody: You're listening to Making Waves, fresh ideas in Freshwater Science. Making Waves is a bimonthly podcast where we discuss new ideas in Freshwater Science and why they matter to you. Making Waves is brought to you with support by the Society for Freshwater Science, Arizona State University, School of Life Sciences and the University of Washington, School of Aquatic and Fishery Sciences. Eric Moody: This is Eric Moody with the Making Waves podcast for the Society for Freshwater Science. This month I'll be talking with Dr. Miguel Cañedo-Argüelles, who is a post-doctoral researcher at the University of Barcelona. Among other things, his research has focused on the effects of reverse salinization on biotic communities and freshwater environments. Thanks for joining me Miguel. Miguel Cañedo-Argüelles: Yeah, thank you very much for the invitation Eric. Eric Moody: My first question for you is, what exactly is reverse salinization or freshwater salinization? What causes this process to happen? Miguel Cañedo-Argüelles: Basically, this is a good question because we use the term a lot. Basically we use it as the increase in dissolved ions or in the US we use the term total dissolved solids, but in the end it's just increase in dissolved salts in rivers. This comes from a lot of different activities, human activities. Miguel Cañedo-Argüelles: I think that the most documented issue is land clearing in Australia. Most of the papers, important papers, early papers come from Australia because they have saline ground waters. The groundwater in many parts of Australia has salts dissolved in it naturally, and so when they clear the trees and they replace it by crops and other kind of vegetation that does not retain water, then the groundwater came up with all those dissolved salts in it and it caused salinization of rivers. -

DISSERTATION IMPLEMENTING ORGANIC AMENDMENTS TO ENHANCE MAIZE YIELD, SOIL MOISTURE, AND MICROBIAL NUTRIENT CYCLING IN TEMPERATE AGRICULTURE Submitted by Erika J. Foster Graduate Degree Program in Ecology In partial fulfillment of the requirements For the Degree of Doctor of Philosophy Colorado State University Fort Collins, Colorado Summer 2018 Doctoral Committee: Advisor: M. Francesca Cotrufo Louise Comas Charles Rhoades Matthew D. Wallenstein Copyright by Erika J. Foster 2018 All Rights Reserved i ABSTRACT IMPLEMENTING ORGANIC AMENDMENTS TO ENHANCE MAIZE YIELD, SOIL MOISTURE, AND MICROBIAL NUTRIENT CYCLING IN TEMPERATE AGRICULTURE To sustain agricultural production into the future, management should enhance natural biogeochemical cycling within the soil. Strategies to increase yield while reducing chemical fertilizer inputs and irrigation require robust research and development before widespread implementation. Current innovations in crop production use amendments such as manure and biochar charcoal to increase soil organic matter and improve soil structure, water, and nutrient content. Organic amendments also provide substrate and habitat for soil microorganisms that can play a key role cycling nutrients, improving nutrient availability for crops. Additional plant growth promoting bacteria can be incorporated into the soil as inocula to enhance soil nutrient cycling through mechanisms like phosphorus solubilization. Since microbial inoculation is highly effective under drought conditions, this technique pairs well in agricultural systems using limited irrigation to save water, particularly in semi-arid regions where climate change and population growth exacerbate water scarcity. The research in this dissertation examines synergistic techniques to reduce irrigation inputs, while building soil organic matter, and promoting natural microbial function to increase crop available nutrients. The research was conducted on conventional irrigated maize systems at the Agricultural Research Development and Education Center north of Fort Collins, CO. -

High-strength organic wastewaters are characterized by chemical oxygen demand (COD) concentrations greater than 4000 mg/L. The effluents of these industries need to undergo biological treatment to remove the organic matter. However, conventional biological treatment processes fail to stabilize high-strength wastewater to regulatory limits. -

Read Full License Page 1/19 Abstract The gut bacteria of insects inuence their host physiology positively, although their mechanism is not yet understood. This study characterized the microbiome of the gut of Spodoptera frugiperda larvae fed with nine different host plants; sugar cane (M1), maize (M2), onion (M3), cucumber (R1), tomato (R2), sweet potato (R3), cabbage L1), green amaranth (L2), and celocia (L3) by sequencing the theV3-V4 hypervariable region of the 16S rRNA gene using Illumina PE250 NovaSeq system. The results revealed that gut bacterial composition varied among larvae samples fed on different host plants. Three alpha diversity indices revealed highly signicant differences on the gut bacterial diversity of S. frugiperda fed with different host plants.. Analysis of Molecular Variance (AMOVA) and Analysis of Similarity (ANOSIM) also revealed signicant variations on the bacterial communities among the various host plants. Five bacteria phyla (Firmicutes, Proteobacteria, Cyanobacteria, Actinobacteria and Bacteroidetes) were prevalent across the larvae samples. Firmicutes (44.1%) was the most dominant phylum followed by Proteobacteria (28.5%). -

JILL SIBLE 3 WELCOME FROM DIRECTOR OF THE OFFICE OF UNDERGRADUATE RESEARCH, KERI SWABY 4 SUMMER RESEARCH PROGRAMS AT VT 5 - 8 INFORMATIONAL BOOTHS 9 ABSTRACTS (ALPHABETICAL) 10 Jill C. Sible, Ph.D. Associate Vice Provost for Undergraduate Education, Professor of Biological Sciences Welcome With great enthusiasm, I welcome all to the 2021 Summer Undergraduate Research Conference at Virginia Tech. This year is particularly exciting to feature both the work of students conducting research remotely as well those who were able to join us in person. Many students presenting today, have spent ten or more weeks immersed in a research project. Summer affords undergraduates the opportunities to dedicate significant time and effort to the planning, execution and analysis of a research project. They have also had the chance to become authentic members of research teams by working with faculty, graduate students, postdoctoral fellows and research staff. Many thanks to all who have mentored undergraduates this summer. Your commitment to undergraduate research is always commendable, and especially this year given the extra challenges you overcame to offer safe and engaging research opportunities during the COVID-19 pandemic. Virginia Tech is pleased to offer these summer experiences not only to our own students, but also to undergraduates from all over the country. We hope that you have enjoyed your time working with Virginia Tech research teams, and we appreciate the diversity of ideas and cultures that you have brought to our research programs.
