Seasonal Baseline Evaluation of Physicochemical Parameters and Culturable Bacterial Characteristics in Northwestern Himalayan Ramsar Sites

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Seasonal monitoring of two Himalayan Ramsar wetlands revealed significant fluctuations in physicochemical parameters and low bacterial diversity across seasons. Elevated dissolved oxygen at Renuka Ji, turbidity and dissolved oxygen at Asan Conservation Reserve levels highlight ecological sensitivity and the need for continuous monitoring and ...

Functional Redundancy Enables Stable Treatment Performance Across Taxonomically Diverse Dairy Wastewater Microbiomes

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Across diverse dairy wastewater systems, microbial communities exhibit strong taxonomic variability yet converge on a conserved set of metabolic pathways. This functional redundancy underpins process stability and consistent treatment performance despite differences in reactor design, influent composition and microbial community structure.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, Volume 600, Issue 18, Page 2729-2743, September 2026.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
