The paper investigates the effects of different commercial carbon and nitrogen sources on the concomitant synthesis of amylase and polygalacturonase enzymes with the aim of optimizing them for maximal enzyme production. The microorganism used in this work was the fungus Trichoderma viride BITRS-1001, which had been previously identified as a highly active producer of amylase and polygalacturonase enzymes. The results showed that the different commercial carbon and nitrogen substrate significantly affected the concomitant syntheses of amylase and polygalacturonase in culture media supplemented with the different commercial carbon and nitrogen substrates. The result obtained suggested that for optimal and concomitant synthesis of the enzymes by Trichoderma viride BITRS-1001 in submerged fermentation, minimal medium supplemented with maltose and casein were the carbon and nitrogen substrates of choice.
本文研究了不同商业碳源和氮源对淀粉酶和多聚半乳糖醛酸酶伴随合成的影响,目的是对其进行优化以实现最大酶产量。本研究使用的微生物是绿色木霉BITRS - 1001,它先前已被鉴定为淀粉酶和多聚半乳糖醛酸酶的高活性生产者。结果表明,不同的商业碳源和氮源底物显著影响了添加不同商业碳源和氮源底物的培养基中淀粉酶和多聚半乳糖醛酸酶的伴随合成。所得结果表明,对于绿色木霉BITRS - 1001在深层发酵中最佳且伴随合成这些酶而言,添加麦芽糖和酪蛋白的基本培养基是首选的碳源和氮源底物。
