    UJI AKTIVITAS ANTIMIKROBA EKSTRAK KO-KULTUR ISOLAT JAMUR LOKAL RIAU Penicillium sp. LBKURCC34 DAN LBKURCC38
    (Elfitra, 2023-05) Azzahroh, Vira; Nurulita, Yuana
    Penicillium sp. LBKURCC34 and LBKURCC38 are fungi isolated from peat soil of the primary forest of the Giam Siak Kecil Bukit Batu Biosphere Reserve (GSKBB) of Riau Province. This fungus is known to have the potential to produce secondary metabolites that have antimicrobial activity. This research was conducted using co-culture technique between Penicillium sp. LBKURCC34 with Penicillium sp. LBKURCC38. Extraction was carried out using ethyl acetate (EtOAc), butanol (BuOH) and acetone (Ase) solvents. These extracts were tested for their antimicrobial activity using the disc diffusion method. The results of the antimicrobial activity test showed that the EtOAc extract at a concentration of 2000 μg/disc had antimicrobial activity against four pathogenic microbes namely S. epidermidis, B. subtilis, E. coli, and C. albicans, BuOH extract only had antimicrobial activity against 2 pathogenic microbes namely B. subtilis and C. albicans, whereas at a concentration of 200 μg/disc, the EtOAc extract only had antimicrobial activity against pathogenic microbes S. aureus and C. albicans. BuOH extract only has activity against S. aureus bacteria, while Ase extract only has activity against C. albicans fungus.
