Existing rooting methods are hampered by evolutionary rate heterogeneity or the unavailability of auxiliary phylogenetic information. We present a novel rooting approach, the minimal ancestor deviation (MAD) method, which embraces heterotachy by utilizing all pairwise topological and metric information in unrooted trees. We demonstrate the method in comparison to existing rooting methods by the analysis of phylogenies from eukaryotes and prokaryotes. MAD correctly recovers the kno wn root of eukaryotes and uncovers evidence for cyanobacteria origins in the ocean. MAD is more robust and co nsistent than existing methods, provides measures of the root inference quality, and is applicable to any tree with branch lengths. -

This article is published with open access Abstract Members of the candidate phylum Acetothermia are globally distributed and detected in various habitats. However, little is known about their physiology and ecological importance. In this study, an operational taxonomic unit belonging to Acetothermia was detected at high abundance in four full-scale anaerobic digesters by 16S rRNA gene amplicon sequencing. The first closed genome from this phylum was obtained by differential coverage binning of metagenomes and scaffolding with long nanopore reads. Genome annotation and metabolic reconstruction suggested an anaerobic chemoheterotrophic 1234567890();,: 1234567890();,: lifestyle in which the bacterium obtains energy and carbon via fermentation of peptides, amino acids, and simple sugars to acetate, formate, and hydrogen. The morphology was unusual and composed of a central rod-shaped cell with bipolar prosthecae as revealed by fluorescence in situ hybridization combined with confocal laser scanning microscopy, Raman microspectroscopy, and atomic force microscopy. We hypothesize that these prosthecae allow for increased nutrient uptake by greatly expanding the cell surface area, providing a competitive advantage under nutrient-limited conditions.

Abstract How microbial metabolism is translated into cellular reproduction under energy-limited settings below the seafloor over long timescales is poorly understood. Here, we show that microbial abundance increases an order of magnitude over a five million-year-long sequence in anoxic subseafloor clay of the abyssal North Atlantic Ocean. -

Analysis of Microbial Contamination of Household Water Purifiers
Applied Microbiology and Biotechnology (2020) 104:4533–4545 https://doi.org/10.1007/s00253-020-10510-5 ENVIRONMENTAL BIOTECHNOLOGY Analysis of microbial contamination of household water purifiers Wenfang Lin1 & Chengsong Ye2 & Lizheng Guo 1,3 & Dong Hu1,3 & Xin Yu2 Received: 23 October 2019 /Revised: 13 February 2020 /Accepted: 28 February 2020 / Published online: 19 March 2020 # Springer-Verlag GmbH Germany, part of Springer Nature 2020 Abstract Household water purifiers are increasingly used to treat drinking water at the household level, but their influence on the microbiological safety of drinking water has rarely been assessed. In this study, representative purifiers, based on different filtering processes, were analyzed for their impact on effluent water quality. The results showed that purifiers reduced chemical qualities such as turbidity and free chlorine. However, a high level of bacteria (102–106 CFU/g)wasdetectedateachstageof filtration using a traditional culture-dependent method, whereas quantitative PCR with propidium monoazide (PMA) treatment showed 106–108 copies/L of total viable bacteria in effluent water, indicating elevated microbial contaminants after purifiers. In addition, high-throughput sequencing revealed a diverse microbial community in effluents and membranes. Proteobacteria (22.06–97.42%) was the dominant phylum found in all samples, except for purifier B, in which Melainabacteria was most abundant (65.79%). For waterborne pathogens, Escherichia coli (100–106 copies/g) and Pseudomonas aeruginosa (100–105 copies/g) were frequently detected by qPCR. Sequencing also demonstrated the presence of E. coli (0–6.26%), Mycobacterium mucogenicum (0.01–3.46%), and P. aeruginosa (0–0.16%) in purifiers. These finding suggest that water from commonly used household purifiers still impose microbial risks to human health. -

In these sediments, subsurface microbial communities are major actors of this cycling but can also affect the sedimentary record and overprint the original paleoenvironmental signal. We therefore investigated the subsurface microbial communities of the oldest lake in Europe, Lake Ohrid (North Macedonia, Albania), to assess the potential connection between microbial diversity and past environmental change using 16S rRNA gene sequences. Along the upper ca. 200 m of the DEEP site sediment record spanning ca. 515 thousand years (ka), our results show that Atribacteria, Bathyarchaeia and Gammaproteobacteria structured the community independently from each other. Except for the latter, these taxa are common in deep lacustrine and marine sediments due to their metabolic versatility adapted to low energy environments. Gammaproteobacteria were often co-occurring with cyanobacterial sequences or soil-related OTUs suggesting preservation of ancient DNA from the water column or catchment back to at least 340 ka, particularly in dry glacial intervals. -
