TL;DR: In this paper, the authors compared the biodegradation and mineralization of ethanol by acclimated and non-acclimated microbial populations in pilot-scale constructed wetlands and demonstrated that the use of incremental priming, together with a vertical subsurface flow mode of operation enhanced long-term function of constructed wetlands.

TL;DR: The results suggest that local physicochemical conditions play a significant role in shaping the bacterial structures in the Central Namib Desert and stress the importance of recording a wide variety of environmental descriptors to comprehensively assess the role of edaphic parameters in shaping microbial communities.

TL;DR: Based on viral richness and read mapping analyses, the salt pan metaviromes were novel and most closely related to each other while showing a low degree of overlap with other environmental viromes.

TL;DR: An extracellular alkaline serine proteinase from Thermus strain ToK3 was isolated and purified to homogeneity by (NH4)2SO4 precipitation followed by ion-exchange Chromatography on DEAE-cellulose and QAE-Sephadex, affinity chromatography on N alpha-benzyloxycarbonyl-D-phenylalanyl-triethylenetetraminyl-Sepha rose 4B and gel-filtration chromatography

TL;DR: This study is the first to uncover the global drivers of desert endolithic diversity using high-throughput sequencing and demonstrates that phototrophs and heterotrophics in the endolithic community assemble under different stochastic and deterministic influences, emphasizing the need for studies of microorganisms in context of their functional niche in the community.
