Cellulase Production from Actinomycetes Isolated from Iraqi Soils: I Characterization of A Cellulolytic Streptomyces Sp. Strain AT7

A cellulolytic actinomycete species was isolated from Iraqi soil, described as a Streptomyces sp. Strain AT7. This strain is characterized by forming nonfragmented vegetative hyphae, spores were found on aerial mycelium in short compact chains (10-20 conidia) and whole cell hydrolysate contained L-diaminopimelic acid and the amino acids: glycine, leucine, and alanine. The strain, grew well on a mineral medium containing carboxymethylcellulose (CMC), produces C, enzyme at different temperatures; 28°, 37° and 48°C and has an acido-alkalophilic growth ability.
