Production of free amino acids by some earthworm-borne microorganisms.

Production of free amino acids by some earthworm-borne microorganisms was investigated in three different synthetic media. Among the fungi tried Gliocladium roseum and Heterocephallum aurantiacum; among bacteria screened Bacillus macerans and B. mycoides; and among actinomycetes tested Streptomyces rimosus, S. violans, S. antibiticus, S. corchorusii and S. atroolivaceus produced significant amount of free amino acids. No correlations could be observed between vegetative growth and free amino acid production.
