Probiotic Bacillus subtilis enhances production efficiency in biofloc‐raised Cherax quadricarinatus via microbiome remodeling and host antioxidant capacity upregulation

open access: yesJournal of the World Aquaculture Society, Volume 57, Issue 2, April 2026.
Abstract Biofloc technology (BFT) presents a sustainable approach to aquaculture intensification by recycling nutrients and reducing water exchange. However, probiotic supplementation for optimization in emerging species such as redclaw crayfish (Cherax quadricarinatus) remains unexplored. This study investigated how Bacillus subtilis (B.

SmallTalk: a novel small‐sized fusion tag for peptide expression and purification

open access: yesFEBS Open Bio, Volume 16, Issue 3, Page 461-473, March 2026.
The SmallTalk fusion tag allows for the efficient expression and purification of soluble recombinant proteins or peptides in Escherichia coli. Testing with SmallTalk‐GFP confirmed that the proteins were soluble and folded correctly, while SmallTalk‐Bin1b maintained its antimicrobial activity against various bacterial isolates. This streamlined workflow

Nitrogen dynamics as a function of pH in soil cultivated with brachiarias

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Brachiaria production is an important segment in Brazil's agriculture, used as a forage or animal feed. Studying the influence of Brachiaria sp. on soil nitrogen (N) dynamics under different soil pH and amendment conditions is a critical research need.
