Research reveals enhanced chitinase activity (56.68 U/ml) in Paenibacillus polymyxa under specific cultural conditions, suggesting potential agricultural applications.
In this study, we investigated the culture conditions to optimize the production of extracellular chitinase from a Paenibacillus sp. strain isolated from rhizosphere of pomelo orchards affected by gummosis. The enzyme exhibited maximum activity (56.68 U/ml) under conditions where soy flour served as the nitrogen source. Colloidal chitin concentration was maintained at 0.3%, initial pH was set to 3 and static culture was maintained at 30oC for 72 hours, with the inoculum continuing at 5% (v/v). The results demonstrate the strain's potential for chitinase production, suggesting its suitability for further development and application in products aimed at preventing gum disease in Thanh Tra pomelo.
