Four hundred bacterial isolates were isolated from rhizosphere of some plants collected from Egypt and screened for production of chitinase enzyme. Only four isolates designated MS1, MS2, MS3 and MS4 were the most potent chitinolytic bacterial species. SDS-PAGE analysis of vegetative and sporulated cells of the four isolates revealed that the protein profile of the four isolates were different ...

The role of the Trichoderma harzianum endochitinase (Ech42) in mycoparasitism was studied by genetically manipulating the gene that encodes Ech42, ech42. We constructed several transgenic T. harzianum strains carrying multiple copies of ech42 and the corresponding gene disruptants. The level of extracellular endochitinase activity when T. harzianum was grown under inducing conditions increased ...

Rotten sweet potato root tuber samples were collected from a barn and experimental field of the CSIR - Plant Genetic Resources Research Institute (PGRRI), Bunso. Isolation identification fungi associated with carried out at Pathology Laboratory same institute. In all, six fungal species belonging to four genera, namely Fusarium solani, Sclerotium rolfsii, Lasiodiplodia theobromae, Aspergillus o...
