P. biglobosa seeds were fermented at various temperature of 40 - ��� ��� �� � � ��� ���� �������� ���� ��� ��� ����������� �� ������� Inoculum. The proximate analysis shows that fermentation increased the percentage protein. Protein had the highest composition with about 51 % after 72 hours at the lowest �� ������ �������� ��� ����������application/pdfTP Chemical technologyConference or Workshop Item
