| Abstract | ||||
| Pectin is a naturally occurring substance that is abundant and has a wide range of uses. It is widely dispersed in different amounts throughout the terrestrial plant's cell walls and middle lamella. The primary constituents of pectin, a heteropolysaccharide, are methanol and galacturonic acid. The pectinase enzyme breaks down pectin to produce several chemicals with industrial uses. A class of enzymes known as pectinases is generated by a variety of organisms, including nematodes, plants, bacteria, fungi, and insects. Pectinases are crucial for numerous industries and are now required commercially for a variety of uses. This study aimed to isolate and screen pectinase-producing fungi from agricultural soils. Sixty fungal isolates belonging to twenty-four species were isolated on culture media supplemented with pectin. All fungal isolates were subjected to morphological identification; the cultural fungal species were identified as Alternaria alternate, Aspergillus carneus, Aspergillus flavus, Aspergillus niger, Aspergillus terreus, Cunninghamella elegans, Curvularia sp, Penicillium citrinum, Syncephalastrum racemosum, and Trichoderma harzianum. Based on screening of all isolated fungi for qualitative pectinolytic activity, the result showed that A.carneus and A.terreus had the highest pectinolytic activity when compared with the other isolated fungal species. | ||||
