Milk‐Clotting Protease From Bacillus stercoris NCCP‐3139: A Potential Microbial Rennet for Cheese Production

Food Science &Nutrition, Volume 14, Issue 5, May 2026.
A milk‐clotting protease from Bacillus stercoris NCCP‐3139 was isolated from soil and purified via ammonium sulfate precipitation and sequential chromatographic techniques, yielding a homogeneous enzyme confirmed by SDS–PAGE. The protease exhibited high catalytic selectivity, with a marked increase in milk‐clotting‐to‐proteolytic activity ratio (50–550)

A ‘Genome‐First’ Framework for Next‐Generation Bioinputs: From Functional Mining to Rational Synthetic Microbial Communities

Environmental Microbiology, Volume 28, Issue 5, May 2026.
I propose a ‘genome‐first’ framework to collapse the phenotypic bottleneck in bioinput discovery. By integrating multi‐layered genome mining and reverse ecology, this paradigm enables the rational design of stable synthetic microbial communities for a data‐driven and sustainable agricultural bioeconomy.

Formate hydrogen lyase mediates stationary-phase deacidification and increases survival during sugar fermentation in acetoin-producing enterobacteria

Frontiers in Microbiology, 2015
Two fermentation types exist in the Enterobacteriaceae family. Mixed-acid fermenters produce substantial amounts of lactate, formate, acetate and succinate, resulting in lethal medium acidification.

Stimulation of Fermentation in Yeasts by Acetoin and Oxygen

Nature, 1966
IN Warburg experiments with ‘resting’ cells, most yeasts show a Pasteur effect, that is, fermentation of glucose is inhibited under aerobic conditions. This effect is generally regarded as an inhibition of fermentation by respiration, for example, as a result of a lack of inorganic phosphate (Pi) or adenosine diphosphate (ADP)1,2.
