Identification of fungi for sweet whey permeate utilization and eicosapentaenoic acid production

Abstract

Eighteen selected organisms of theEumycota division of the fungi kingdom were examined for eicosapentaenoic acid production and utilization of sweet whey permeate. The organisms belong to the subdivisionsMastigomycotina, Zygomycotina, Ascomycotina andDeuteromycotina. Seven organisms were initially identified as lactose utilizers (the predominant sugar in sweet whey permeate_ and eicosapentaenoic acid (EPA) producers. Utilization of lactose was demonstrated and EPA production was confirmed for four organisms, all of the subdivisionMastigomycotina. Growth studies showed thatP. ultimum had the best potential for future work.
