Fructooligosaccharides (FOS) production by Penicillium expansum was evaluated. In a first stage, the best conditions for P. expansum growth and sporulation were established with potato/dextrose/agar being the most suitable medium at between 22 and 25 degrees C, giving good growth and good sporulation. The inocula from this medium were used for FOS production using shake-flask cultures, and yielded 0.58 g FOS/g sucrose (3.25 g FOS/l.h), demonstrating the potential of this strain for sucrose conversion to FOS.
评估了扩展青霉产生果寡糖（FOS）的情况。在第一阶段，通过土豆/葡萄糖/琼脂确定了扩展青霉生长和产孢的最佳条件，在 22 到 25 摄氏度之间最适合，能使生长和产孢都达到良好的状态。使用摇瓶培养从该培养基中接种，产生了 0.58 克 FOS/克蔗糖（3.25 克 FOS/升/小时），证明了该菌株将蔗糖转化为 FOS 的潜力。
