Riboflavin formation by some mold fungi cultivated on hydrocarbon containing media

ABSTRACT

The potentiality of some mold fungi isolated from petroleum sludge-to produce riboflavin when grown on hydrocarbon-containing media was tested. Aspergillus terreus was found to be distinguished by its capacity to produce riboflavin when cultivated on the different culture media tested. It was able to grow more luxuriantly and produce good riboflavin output on solar containing medium. Solar concentration of 5% v/v favoured high riboflavin productivity. However, maximal B[2]yields were achieved after 20 days incubation at 30?C. Initial pH value of 5.5-6.0 was found to be optimum for growth of A. terreus and its riboflavin production
