Eighty soil and sewage samples were collected from different environmental locations to isolate isoamylase producing Pseudomonas. From these samples, 100 isolates were obtained, among them 40 were identified as Pseudomonas sp. according to the morphological characteristics and biochemical tests. These isolates were screened to examine their ability in isoamylase production. Results showed that all these isolates were producers of isoamylase. An isolate (Pseudomonas sp.

In an attempt to treat infection of mice skin using ethanolic extract of  rosemary (Rosmarinus officinalis) callus cultures. Several experiments were carried out. Callus was induced on leaf explants and maintained for 30 days on Murashige and Skoog medium supplemented with 0.5 mg/l of benzyl adenine and 2.0 mg/l of 2,4-dichlorophenoxyacetic acid. Water and ethanolic extracts of R. officinalis leaves and callus cultures were investigated for their antimicrobial activity.
