- 摘要:
- 以枯草芽孢杆菌KD1发酵代谢产物为试材，采用统计分析及食品分析检测等方法，研究KD1发酵代谢产物对香菇菌丝生长、子实体性状、香菇产量以及香菇营养成分的影响，并探究该代谢产物的储存稳定性。结果表明：相比于对照组，KD1发酵代谢产物对菌丝生长速度最大提升率达9.64%，同时显著改良子实体性状；在产量方面，前4批次总出菇量提升18.59%，最大单潮香菇产量提升35.40%；在营养成分方面，丰富了香菇中游离氨基酸含量和种类，香菇中游离必需氨基酸总量提升38.46%，新增亮氨酸和异亮氨酸2种氨基酸；且代谢产物在室温下可长期稳定保存。综上所述，KD1发酵代谢产物应用于香菇生产具有巨大潜力与广阔发展前景。
- Abstract:
- The fermentation metabolites of Bacillus subtilis KD1 were selected as test materials to clarify effects on the growth of mycelium,fruit body traits,yield and nutritional content of Lentinus edodes,as well as its storage stability.And various experimental methods such as statistical analysis and food analysis were used in this research.The results showed that the KD1 fermentation metabolites could significantly accelerate mycelial growth compared to the control group,with the maximum growth rate increasing by 9.64%;meanwhile,fruiting body traits were also improved significantly;moreover,the total yield of the first four batches of Lentinus edodes increased by 18.59%,and the yield of the largest single tide of Lentinus edodes increased by 35.40%;in terms of nutrients,the content and types of free amino acids in Lentinus edodes were significantly enriched;the total amount of free essential amino acids in Lentinus edodes was increased by 38.46%,and two new amino acids,leucine and isoleucine were added.Besides,the metabolites could be stored stably for a long time at room temperature.The results indicated that the application of KD1 fermentation metabolites in the production of Lentinus edodes has a broad development prospect.
