The effect of calcium and magnesium on the aggregation of a purple phototrophic bacteria mixed consortium

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND An essential aspect of applying Purple Phototrophic Bacteria (PPB) technology for wastewater treatment is the biomass separation from the aqueous phase. Ca2+ and Mg2+ have been used to enhance the aggregation of different biological matrices. In this paper, the effect of Ca2+ and Mg2+ on the aggregation of a mixed culture of PPB was

Polyesterase activity and thermostability of carboxylesterases from Thermoleophilum album YS‐3

The FEBS Journal, EarlyView.
Three novel α/β‐hydrolases from thermophilic bacterium Thermoleophilum album display carboxylesterase and polyesterase activity. These enzymes hydrolyse PET, PLA and PCL both at high and moderate temperatures. TA21 shows superior activity, efficiently converting MHET to terephthalic acid. Structural features underlying substrate binding highlight their

Structural Homology of Reaction Centers from Rhodopseudomonas sphaeroides and Rhodopseudomonas viridis as Determined by X-ray Diffraction [PDF]

, 1986
Crystals of the reaction center (RC) from Rhodopseudomonas sphaeroides with the space group P2_12_12_1, have been studied by x-ray diffraction. The Patterson search (molecular replacement) technique was used to analyze the data, with the structure of the

Interaction Among Microbiota, Chemical Composition, and Quality Variations in Coffea arabica Across Altitudinal Gradients During Wet Processing

Food Science &Nutrition, Volume 14, Issue 8, August 2026.
Fermentation significantly altered the dominant bacterial genera from Sphingomonas and Pleomorphomonas (before fermentation) to Weissella and Lactobacillus (after fermentation), while Cladosporium and Fusarium remained the dominant fungal genera. Notably, non‐volatile compounds in de‐pulping coffee beans and volatile compounds of roasted coffee beans ...

Multidimensional optimization for accelerating light-powered biocatalysis in Rhodopseudomonas palustris

Biotechnology for Biofuels and Bioproducts, 2023
Background Whole-cell biocatalysis has been exploited to convert a variety of substrates into high-value bulk or chiral fine chemicals. However, the traditional whole-cell biocatalysis typically utilizes the heterotrophic microbes as the biocatalyst ...

Horizontal Gene Transfer and Genome Rearrangements Shape Bacterial Adaptation for Bioremediation

Environmental Microbiology, Volume 28, Issue 7, July 2026.
Exposure to xenobiotics triggers genome evolution and horizontal gene transfer (HGT), driving the acquisition of novel catabolic functions. These genomic adaptations provide a competitive fitness advantage that reshapes microbial community structure and enhances biodegradation impact.
