摘要: [目的]分析不同处理灵芝菌丝体生长情况,研究蓝光对灵芝菌丝生长速度、生物量、多糖及4种糖代谢相关酶的影响。[方法]以灵芝菌丝体为实验材料,采用苯酚-硫酸法测定灵芝多糖含量,测定灵芝菌丝体4种糖代谢相关酶活性。[结果]研究发现,蓝光处理菌丝体生长速度、多糖含量、己糖激酶(HK)活性、葡萄糖-6-磷酸脱氢酶(G-6-PDH)活性、磷酸葡萄糖异构酶(PGI)活性和α-磷酸葡萄糖变位酶(α-PGM)活性均高于黑暗对照,均是先升后降的变化趋势,蓝光处理菌丝体生物量积累也高于黑暗对照。[结论]结果表明,蓝光可以促进灵芝菌丝体的生长,促进多糖的积累和相关酶活的活性。

Abstract: This study is aimed at finding the effects of blue light on the growth rate, biomass, polysaccharides and four kinds of glycometabolism-related enzymes ofGanoderma lucidum mycelium. With dark culture as control, the growth rate and biomass ofG.lucidum mycelia irradiated with the blue light were determined. The contents of polysaccharides were determined by the phenol-sulfuric acid method and the activities of the four kinds of glycometabolism-related enzymes were measured. Results showed that the growth rate, the contents of the ploysaccharides, the activities of hexokinase (HK), glucose-6-phosphate dehydrogenase (G-6-PDH), α- phosphoglucomutase (α-PGM) and phosphoglucose (PGI) ofG.lucidum mycelia irradiated with the blue light were significantly higher than those of dark culture, they both increased first and then decreased. The biomass accumulation irradiated with the blue light was higher than that of dark culture. In conclusion, the blue light could promote the growth rate, the accumulation of polysaccharides, the activities of glycometabolism-related enzymes ofG.lucidum mycelia.
