Antibacterial Activity of Endophyte Marasmius cladophyllus UMAS MS8

The antibacterial activity of Marasmius cladophyllus was evaluated with different species of bacteria which consists of gram-negative bacteria and gram-positive bacteria. Different solvents; ethyl acetate and ethanol, were used to extract the bioactive compounds from supernatant and fungal biomass....
