ABSTRACT:
A biologically pure culture of cellulase-elaborating bacteria of mutant microorganisms of Cellulomonas (ATCC-21399) which have the ability to excrete L-glutamic acid or L-lysine, or both, when the mutant microorganisms are grown in a fermentation medium in the substantial absence of yeast extract on an assimilable source of carbon, and supplied with nitrogen and mineral nutrients, in the presence of oxygen at temperatures ranging from about 20.degree. C. to about 40.degree. C. The preferred mutant microorganisms are selected from the group consisting of: Cellulomonas sp. ATCC-21399 strain LC-10 (ATCC-31230), Cellulomonas sp. ATCC-21399 strain A.sup.r -1 (ATCC-31231) and Cellulomonas sp. ATCC-21399 strain A.sup.r -156 (ATCC-31232).
