Proteases and lipases activity of fungi isolated from local cheese, Republic of Yemen

Abstract EN

A 99 fungal isolates represented 25 species related to 7 genera were isolated in the current study.

They were screened for their ability to produce lipase and protease enzymes from the 35 positive isolates for protease.

There are only 3 isolates could produce the enzyme in moderate activity which related to Aspergillus niger and A.

sydowii.

The remaining isolates 32 (91.4 % of the positive isolates) have weakly enzyme production and these belonging to A.

flavus, A.

sydowii, A.

tamarii, M.

racemosus, P.

citrinum and P.

oxalicum.

The results revealed that from the 99 tested isolates, about 34 isolates (34.34 %) could produce lipase.

9 isolates (9.1%) of P.

citrinum exhibited high activity for lipase production.

Whereas, 8 isolates (8.1%) belonging to P.

expansum, P.

islandicum and P.

paxilli could produce lipase enzyme in moderate ability.

While the isolates of Mucor circinelloides, M.

racemosus P.

oxalicum and P.

roqueforti were weakly producers.
