The potentiality of some mould 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. A solar concentration of 5% v/v favoured high riboflavin productivity. The maximal vitamin B2 yields were achieved after 20 days incubation at 30 degrees C. An initial pH value of 5.5-6.0 was found to be the optimum for growth of A. terreus and for riboflavin production.
对从石油污泥中分离出的一些霉菌在含烃培养基上生长时产生核黄素的潜力进行了测试。发现土曲霉在测试的不同培养基上培养时，具有产生核黄素的能力。在含太阳能的培养基上，它能够生长得更加茂盛，并产生良好的核黄素产量。太阳能浓度为5%（v/v）有利于高核黄素生产率。在30摄氏度下培养20天后，可获得最大的维生素B2产量。发现初始pH值为5.5 - 6.0是土曲霉生长和核黄素生产的最佳值。
