Knowledge of structure and function of microbial communities in different 18 successional stages of biological soil crusts (BSCs) is still scarce for desert areas. In this study, 19 Illumina MiSeq sequencing was used to assess the composition changes of bacterial communities 20 in different ages of BSCs in the revegetation of Shapotou in the Tengger Desert. The most dominant 21 phyla of bacterial communities shifted with the changed types of BSCs in the successional stages, 22 from Firmicutes in mobile sand and physical crusts to Actinobacteria and Proteobacteria in BSCs, 23 and the most dominant genera shifted from Bacillus, Enterococcus and Lactococcus to 24 RB41_norank and JG34-KF-361_norank. Alpha diversity and quantitative real-time PCR analysis 25 indicated that bacteria richness and abundance reached their highest levels after 15 years of BSC 26 development.

  • Extreme Organisms on Earth Show Us Just How Weird Life Elsewhere Could Be. by Chris Impey Astrobiology
    Astrobiology Extreme organisms on Earth show us just how weird life elsewhere could be. by Chris Impey How life could thrive on hostile worlds Humans have left their mark all over Earth. We’re proud of our role as nature’s generalists — perhaps not as swift as the gazelle or as strong as the gorilla, but still pretty good at most things. Alone among all species, technology has given us dominion over the planet. Humans are endlessly plucky and adaptable; it seems we can do anything. Strain 121 Yet in truth, we’re frail. From our safe living rooms, we may admire the people who conquer Everest or cross deserts. But without technology, we couldn’t live beyond Earth’s temperate zones. We cannot survive for long in temperatures below freezing or above 104° Fahrenheit (40° Celsius). We can stay underwater only as long as we can hold our breath. Without water to drink we’d die in 3 days. Microbes, on the other hand, are hardy. And within the microbial world lies a band of extremists, organisms that thrive in conditions that would cook, crush, smother, and dissolve most other forms of life. Collectively, they are known as extremophiles, which means, literally, “lovers of extremes.” Extremophiles are found at temperatures above the boiling point and below the freezing point of water, in high salinity, and in strongly acidic conditions. Some can live deep inside rock, and others can go into a freeze-dried “wait state” for tens of thousands of years. Some of these microbes harvest energy from meth- ane, sulfur, and even iron.

Correspondence and The biosynthetic pathway for the rare compatible solute mannosylglucosylglycerate (MGG) accumulated by requests for materials Rhodopirellula baltica, a marine member of the phylum Planctomycetes, has been elucidated. Like one of the should be addressed to pathways used in the thermophilic bacterium Petrotoga mobilis, it has genes coding for J.C. ([email protected].) glucosyl-3-phosphoglycerate synthase (GpgS) and mannosylglucosyl-3-phosphoglycerate (MGPG) synthase (MggA). However, unlike Ptg. mobilis, the mesophilic R. baltica uses a novel and very specific MGPG phosphatase (MggB). It also lacks a key enzyme of the alternative pathway in Ptg. mobilis – the mannosylglucosylglycerate synthase (MggS) that catalyses the condensation of glucosylglycerate with GDP-mannose to produce MGG. The R. baltica enzymes GpgS, MggA, and MggB were expressed in E. coli and characterized in terms of kinetic parameters, substrate specificity, temperature and pH dependence.

  • Astr 450 Assignment 5: Earth-Based Life in Extreme Environments Due Thu Feb 19, 2009
    Astr 450 Assignment 5: Earth-based life in extreme environments due Thu Feb 19, 2009 An ”extremophile” is an organism that thrives in extreme environments, where ”extreme” means different from the Earth surface norms in temperature, pressure, or composition. ”Thrive” in this context means that these conditions are ideal for the organism, and in fact, most extremophiles would perish if brought to Earth-normal conditions. For each of the following categories of extremophile, identify (i) the extreme condition with numerical values, and (ii) at least one location on Earth where these extreme conditions are realized, and (iii) if in your researches you come across a type of organism that does not ultimately rely upon the Sun as its source of energy, then please make a note if it. 1. Acidophile 2. Alkalophile 3. Thermophile 4. Psychrophile 5. Piezophile (also called a barophile) 6. Lithophile (also called an endolith) 7. Halophile You must include a bibliographic entry for all sources you use. You can organize this information in chart form if you wish, but it is certainly not required. Finally, quickly skim the wikipedia article on the bacterium named “deinococcus radiodurans” and tell me the (surprising) extreme condition it can tolerate which is NOT on the list above. Ref: http://en.wikipedia.org/wiki/Deinococcus radiodurans Requirements for a good assignment • The assignment will be graded strictly, as expected for a 400-level course. The assignment is graded out of 30 points. • Have your name, SID, and a word count at the top of the paper. Use question-and-answer format when writing your assignment, do NOT hand in a run-on paragraph (50% penalty).

Here, we assessed the biogeographical patterns of species assemblages, prevalence and impact of endolithic parasitism in two mussel species that act as important ecosystem engineers in the southern African intertidal habitat, Perna perna and Mytilus galloprovincialis. We conducted large-scale surveys across three biogeographic regions along the South African coast: the subtropical east coast, dominated by the indigenous mussel, P. perna, the warm temperate south coast, where this species coexists with the invasive Mediterranean mussel, M. galloprovincialis, and the cool temperate west coast dominated by M. galloprovincialis. Infestation increased with mussel size, and in the case of M.

  • The Influence of Sodium Chloride on the Performance of Gammarus Amphipods and the Community Composition of Microbes Associated with Leaf Detritus
    THE INFLUENCE OF SODIUM CHLORIDE ON THE PERFORMANCE OF GAMMARUS AMPHIPODS AND THE COMMUNITY COMPOSITION OF MICROBES ASSOCIATED WITH LEAF DETRITUS By Shelby McIlheran Leaf litter decomposition is a fundamental part of the carbon cycle and helps support aquatic food webs along with being an important assessment of the health of rivers and streams. Disruptions in this organic matter breakdown can signal problems in other parts of ecosystems. One disruption is rising chloride concentrations. Chloride concentrations are increasing in many rivers worldwide due to anthropogenic sources that can harm biota and affect ecosystem processes. Elevated chloride concentrations can lead to lethal or sublethal impacts. While many studies have shown that excessive chloride uptake impacts health (e.g. lowered respiration and growth rates) in a wide variety of aquatic organisms including microbes and benthic invertebrates). The impacts of high chloride concentrations on decomposers are less well understood. My research objective was to assess how increasing chloride concentrations affect the performance and diversity of decomposer organisms in freshwater systems. I experimentally manipulated chloride concentrations in microcosms containing leaves colonized by microbes or containing leaves, microbes and amphipods. Respiration rate, decomposition, and community composition of the microbes were measured along with the amphipod growth rate, egestion rate, and mortality. Elevated chloride concentration did not impact microbial respiration rates or leaf decomposition, but had large impacts on bacteria community composition. It did cause a decrease in instantaneous growth rate, and 100% mortality in the highest amphipod chloride treatment, but amphipod egestion rate was not significantly affected. The results of my research suggest that the widespread increases in chloride concentrations in rivers will have an impact on decomposer communities in these systems.

  • Applying Genome-Resolved Metagenomics to Deconvolute the Halophilic Microbiome
    Review Applying Genome-Resolved Metagenomics to Deconvolute the Halophilic Microbiome Gherman Uritskiy and Jocelyne DiRuggiero * Department of Biology, Johns Hopkins University, Baltimore, MD 21218, USA; [email protected] * Correspondence to: [email protected] Received: 15 February 2019; Accepted: 11 March 2019; Published: 14 March 2019 Abstract: In the past decades, the study of microbial life through shotgun metagenomic sequencing has rapidly expanded our understanding of environmental, synthetic, and clinical microbial communities. Here, we review how shotgun metagenomics has affected the field of halophilic microbial ecology, including functional potential reconstruction, virus–host interactions, pathway selection, strain dispersal, and novel genome discoveries. However, there still remain pitfalls and limitations from conventional metagenomic analysis being applied to halophilic microbial communities. Deconvolution of halophilic metagenomes has been difficult due to the high G + C content of these microbiomes and their high intraspecific diversity, which has made both metagenomic assembly and binning a challenge. Halophiles are also underrepresented in public genome databases, which in turn slows progress. With this in mind, this review proposes experimental and analytical strategies to overcome the challenges specific to the halophilic microbiome, from experimental designs to data acquisition and the computational analysis of metagenomic sequences. Finally, we speculate about the potential applications of other next- generation
