Isolation of Endophytic Bacteria from Medicinal Plants and Screening for Their Enzyme Production Ability

Shokhiddinova M.N*, Normurodova Q.T.

A total of 45 isolates were isolated from the roots, stems, and leaves of medicinal plants found in fields and yards such as Plantago major L., Hypericum perforatum L., Kalanchoe daigremontiana, Cichorium intybus L., Melissa officinalis L., Mentha piperita L., Matricaria recutita L. Among them, it was observed that endophytic bacteria were found relatively more in Kalanchoe daigremontiana and Cichorium intybus L. Isolate KD-L7 extracted from the leaves of the medicinal plant Kalanchoe daigremontiana has a high affinity for 1% casein and 1% starch, the size of its hydrolysis zone was 6-10 mm, its α-amylose activity was 14.2 units/ml, whereas protease activity was 28.6 units/ml.
