摘要
菌体形态是影响霉菌代谢的重要因素。主要考察了煤油和不同表面活性剂对三孢布拉氏霉菌菌体形态及番茄红素合成能力的影响。结果表明:当添加煤油和triton-X100形成菌丝球时,该菌丝形态不利于物质的传递,细胞合成番茄红素的能力无明显变化。而当添加水溶性表面活性剂span-20时,形成粗、短分散型的菌丝体,强化了传质,促进了番茄红素的合成,番茄红素生产能力提高了近3倍。
Mycelial morphology are exploited a great influnence to the metabolites of fungi. The effect of the mycelial morphology on producing lycopene by Blakeslea tripora was investigated. The results indicated that pellets has little role on fermentation when adding kerosene and triton-x100, However, The content of lycopene in the medium reached to 98.6mg/L by adding Ig/L span-20, forming dispersed mycelia, which is 3 times of the control experiments.
