Azadirachta indica (Neem) Seed Extracts: A Supplement for Culture Medium for Growth of Aspergillus niger
The effectiveness of Neem seed extracts (Azadirachta indica A. Juss) was tested against Aspergillus niger isolated from soil to determine whether the neem seed extracts will inhibit or enhance the growth of Aspergillus niger .
Three different concentrations of neem seed extracts were prepared 10%, 20% and 50%. The results showed that the neem seed extracts enhanced the growth of Aspergillus niger from 24 hours of incorporation up to 120 hours. The growth enhancement was also found to increase with concentration of the seed extracts.
