Abstract

Thirty seven actinomycetes isolates were isolated from Damietta soil using starch nitrate agar media. These isolates were screened for APPL (acid precipitable polymeric lignin) by using minimal salts-yeast extract medium with rice and wheat straws. Three actinomycetes isolates showed high APPL production. These isolates also showed production of cellulase and xylanase with different levels. These isolates were identified by using morphological, physiological and chemotaxonomy criteria and were identified as Streptomyces canus, Streptomyces libani and Streptomyces cyaneus.
