Microbial community-based bacterial protein from soybean-processing wastewater as a value-added alternative fish feed ingredient for Asian sea bass (Lates calcarifer)

This study evaluates microbial community-based single cell protein from soybean wastewater as a fishmeal substitute for Asian sea bass, finding no significant differences in growth metrics between groups.

Microbial community-based production of single cell protein from soybean-processing wastewater of variable chemical composition

This study demonstrates microbial community-based production of single cell protein from soybean-processing wastewater with varying chemical composition, showing higher SCP yields with higher nitrogen content and lower carbon-to-nitrogen ratios.

Microbiome assembly predictably shapes diversity across a range of disturbance frequencies

This study shows that disturbance frequency affects microbial community assembly processes, which in turn predictably influence diversity and function.
