摘要
目的研究不同质量分数的Cu2+、Fe3+、Cr3+和Ca2+对竹黄菌液体发酵产竹红菌素量和菌丝体生物量的影响。方法向培养基中添加不同质量分数的金属离子,在27℃、130 r/min下培养96 h。结果 Cr3+的质量分数为0.005%时竹红菌素及菌丝体生物量最大;Fe3+的质量分数为0.003%时菌丝体生物量最高,0.005%时竹红菌素量最高;Ca2+的质量分数为0.03%时最有利于菌丝体生长,0.05%时最能促进竹红菌素的分泌;Cu2+的质量分数为0.03%时生物量及竹红菌素量均达到最大值。结论添加金属离子后,菌丝体干质量最高达15.28 g/L,竹红菌素量最高达8.12 mg/g。
Objective To study the effect of different levels of Cu2＋,Fe3＋,Cr3＋,and Ca2＋ on mycelia biomass and the hypocrellin yield by submerged culture of Shiraia bambusicola.Methods The fungis were cultured under 27 ℃ and 130 r/min for 96 h with each level of metal ions.Results The biomass and the hypocrellin yield were the highest with Cr3＋ of 0.005%;Fe3＋ of 0.003% and 0.005% contents were favorable to the biomass and the hypocrellin yield,respectively;Ca2＋ content of 0.03% was suitable for the mycelia growth and the hypocrellin yield benefited from the concentration of 0.005%;Cu2＋ content of 0.03% was added,both the biomass and the hypocrellin yield reached the best.Conclusion The highest mycelia dry weight and the hypocrellin yield could reach 15.28 g/L and 8.12 mg/g,respectively in addition of metal ion.
