Aims of present study were to isolate and characterize chitinase producing fungi from soil samples of apple orchards of Shimla and Kinnaur district of Himachal Pradesh. The soil samples were collected aseptically and subjected to serial dilution to isolate the fungal strains. Total nine morphologically different fungi were isolated and screened for their chitinolytic activity in colloidal chitin incorporated media through zone assay. The isolates were screened based on the size of the zone formed. Best chitinase producers were subjected 18S ribosomal RNA sequencing. After molecular characterization of two isolates, they were identified as Alternaria brassicicola strain and Pencillium sp. isolate. A novel strain, Acinetobacter ASK18, a gram-negative, motile organism was identified. These isolates would further be subjected to purification of the enzyme produced and hence could be evaluated as effective biocontrol agents against pathogenic bacteria and fungi.
