Jurnal mikologi Indonesia: Identifikasi morfologi rhizopus pada oncom hitam dari berbagai daerah di Indonesia
Oncom hitam is an authentic Indonesian fermented product made from peanut meal as a
substrate and Rhizopus spp. as a fermentation agent. Rhizopus, which plays a role in the
process of making black oncom, needs to be identified and conserved for further development
of fermented foods that are safe for consumption. This study was aimed to isolate and identify
Rhizopus on black oncom. Samples were taken from several traditional markets in DKI
Jakarta, West Java, and East Java. Identification of Rhizopus was carried out based on a
morphological examination such as spores, columella and rhizoid, and sporangiophore
length; in combination with a physiological approach at different growth temperatures (33,
42, 46, 48, and 51°C) on potato dextrose agar medium. Identification was carried out
following the "A Monograph of Rhizopus". A total three species of Rhizopus was determined
from black oncom, namely, R. arrhizus var. delemar (R. delemar), R. arrhizus var.
Tonkinensis (R. oryzae), and R. microsporus var. chinensis. All of them arenew reports
associated with black oncom in Indonesia.
