Soybean spp. Spontaneously Produce Abundant and Diverse Temperate Phages in Culture.

Soybean bradyrhizobia ( spp.) are symbiotic root-nodulating bacteria that fix atmospheric nitrogen for the host plant. The University of Delaware Culture Collection (UDBCC; 353 accessions) was created to study the diversity and ecology of soybean bradyrhizobia.

Purification and characterization of the thermostable protease produced by Serratia grimesii isolated from channel catfish.

Background: Microbial spoilage of fishery products accounts for significant financial losses, yearly on a global scale. Psychrotrophic spoilage bacteria often secrete extracellular enzymes to break down surrounding fish tissue, rendering the product unsuitable for human consumption. For a better understanding of bacterial spoilage due to enzymatic digestion of fish products, proteases in Serratia grimesii isolated from North American catfish fillets (Ictalurus punctatus) were investigated.
