摘要
以0.1mol/L氢氧化钠作为平板PDA培养基碱化剂,壳灰作为培养料的碱化剂,考察微碱化培养基对香菇菌丝生长的影响。试验结果表明:2种碱性物质均可显著提高灭菌后培养基的pH;不同碱化程度的培养料在菌丝生长过程中pH均不断下降,并逐步趋于一致。PDA培养基和培养料pH为6时菌丝生长速度较快,长势较好。
To investigate the effect of the micro-alkalization of growth media on the mycelia growth of Lentinula edodes,0.1 mol/L NaOH and shell ash as alkalized agents were added to PDA medium and solid lignocellulosic substratesrespectively.Results showed that the pH of the growth media can be improved by both alkalized agents before and after sterilization.For all the tested solid substrates,the pH decreased gradually during the mycelia growth of L.edodes,and reached nearly almost equal levels at the end of the incubation.In terms of mycelial growth rate and density,PDA medium with initial pH 6.0(0.1 mol/L NaOH as alkalization agent),and solid substrates with initial pH 6.0(2.0%shell ash as alkalization agent)was the best.
