...results against selected phytopathogens compared to GNB medium and selected for further study. Crude (1 µg.mL-1 ) obtained from PDB medium showed 2.50 ± 0.64 mm and 1.97 ± 0.21 mm inhibition zone against X. campestris and C. michiganensis respectively compared to positive reference (streptomycin) and negative refrence (EtOAc) using disc diffusion method. However, the same concentration of crude (1 µg.mL-1) showed 62.20 ± 2.51% ...

...otiorum is a serious phytopathogen resulting in significant loss of crop yield. Trichderma hamatum has the capacity to inhibit S. sclerotiorum growth by production of toxic metabolites and mycoparasitism. In vitro bioassays were used to evaluate the efficacy of T. hamatum and difenoconazole alone or its combinations against S. sclerotiorum. The results showed that T. hamatum could infect and destroy the mycelia and...

...ial activity against two phytopathogenic bacterial species (Clavibacter sp. and Xanthomonas sp.) and a human pathogenic bacterium (Escherichia coli) in 2016. Experiment was carried out by using complete randomized design with three replications in vitro. Phytochemical analysis reveals that the methanolic fraction of oil possesses metabolites like carbohydrates, amino acids, alkaloids, flavonoids and glycosides. To test the antibacterial activity of the extract...

Chitinase production in organisms: a review
...e enzyme have control of phytopathogens, physiological functions and degradation of chitinous waste. Interest in chitin wastes utilization is increasing day by day because of its natural resistance against degradation. The review focused on different sources of naturally chitinase production in organisms was discussed.
