Streptomyces cellulolyticus sp. nov., a new cellulolytic member of the genus Streptomyces.

Actinomycete strain LXT (T = type strain), which decomposes cellulose, was identified as a member of the genus Streptomyces on the basis of morphological characteristics and the chemotype of the cell wall. The key characteristics of this organism are rectiflexibiles spore chains, a nonfragmenting vegetative mycelium, a warty spore surface, a type I cell wall, white to pink spore masses, and a lack of formation of soluble pigments (including melanin). These results indicate that strain LXT represents a distinct Streptomyces species, for which the name Streptomyces cellulolyticus is proposed. The type strain is strain LX, which has been deposited in the China General Microbiological Culture Collection Center as strain AS. 41332.
