[Life] The RNA World theory was proposed as a way to explain the origin of the DNA-RNA-Protein relationship found all current cells. It has been greatly strengthened by experimental work on ribozymes and non-enzymatic replication, and has become the most…
Shotgun metagenomics sequences DNA collected from an entire community rather than from a single isolated organism. In soil, that means mixing genetic fragments from bacteria, fungi, plants, and other life forms. Researchers then need to determine where those fragments came…
Whole-genome sequencing of two Aphanothece strains from a Southern Brazilian estuary reveals conserved lipid genes but strain-specific fatty acid outputs shaped by temperature and light.
Several soil properties differed between the two vegetation types. Total nitrogen and soil organic carbon stocks did not differ significantly, but Phragmites soils showed higher bulk density, and Sporobolus soils had higher carbon-to-nitrogen ratios. Soil pH differed between vegetation types…
A 12-run Plackett–Burman screening identified agitation speed, sodium nitrate, magnesium sulphate and carbon source as the dominant factors raising extracellular protease production by Bacillus sp. MTCC 511 up to 20.6-fold under mutagenic stress.
New Zealand researchers sustained methane-eating microbes in 45-degree-Celsius, pH 2.2 reactors for 700 days, reaching elimination capacities of 41.9 grams per cubic meter per hour under microaerobic conditions.
A new review details how microbial exopolysaccharides boost microbial fuel cell power output, bind heavy metals, and enable green nanomaterials, while commercialization hurdles remain. Article Title: Versatile applications of EPS secreting Microbes: advances in microbial fuel cells and beyond News…

Researchers in Japan engineered ancestral nucleoside diphosphate kinase variants with restricted amino acid repertoires to explore alternative catalytic functions. One variant, Arc1-12KR, retained its protein fold despite lacking catalytic histidine and unexpectedly converted two ADP molecules into ATP and AMP. The…
The Microbial Biogeochemistry Laboratory Core Technology Team (CTT) as part of the Environmental Health Program focuses on environmental questions in aquatic systems (sediment and water) involving the linkages between major biogeochemical cycles (those involving carbon, sulfur, iron and nitrogen) and…
Bacteria and archaea as organisms: microbial ecology, biofilms and extremophiles, and how bacteria live, communicate and evolve.
