由于白酒行业对传统工艺要求较高，对微生物的新技术领域探索仍有许多不足之

Because the liquor industry has high requirements for traditional craftsmanship, there are still many deficiencies in the exploration of new technologies in microorganisms. For example, the screening of good strains is cumbersome and difficult, and only a handful of good strains can be screened in many regions. With the continuous progress of science and the rapid development of genetic engineering and DNA extraction technology, people will continue to deepen their research on fungi. Therefore, an appropriate method is selected to obtain pure fungal strains, and the obtained pure strains are identified. Through morphological observation, they can be classified more correctly, so as to accurately understand the diversity of culturable fungi in Laolongkou Daqu. The effective development and utilization of fungal resources have laid a certain foundation. In view of the public demand and consumer market, Luzhou-flavor liquor still occupies a large share and has a large space for development, which has far-reaching significance for research.

Due to the high demand for traditional technology in Baijiu industry, there are still many deficiencies in the exploration of new technology fields. For example, the operation of screening excellent strains is cumbersome and difficult, and only a few excellent strains can be screened in many regions, and some strains are regional, the effect is not obvious, unstable and vulnerable to environmental impact. With the continuous development of science, the rapid development of genetic engineering and DNA extraction technology will also deepen the research of fungi. The potential of fungi will be excavated, and the quality and output of Baijiu will also have a qualitative leap. Therefore, select appropriate methods to obtain pure strains of fungi, identify the pure strains, and classify them more correctly through morphological observation, so as to accurately understand the diversity of culturable fungi in Laolongkou Daqu and lay a certain foundation for the effective development and utilization of fungal resources. In view of the public demand and the consumer market, Luzhou Baijiu still has a large share of the development space, and has far-reaching significance.

Due to the high requirements of traditional technology in liquor industry, there are still many shortcomings in the exploration of new technology fields of microorganisms. For example, at present, the operation of screening excellent strains is cumbersome and difficult, and only a handful of excellent strains can be screened in many areas, and some strains have strong regionality, inconspicuous and unstable effects, and are easily affected by the environment, etc. With the continuous progress of science, the rapid development of genetic engineering and DNA extraction technology, people's research on fungi will continue to deepen, and a series of potential of fungi will be tapped by people, and the quality and output of liquor will also have a qualitative leap. Therefore, we should choose a suitable method to get pure fungus strains, and identify the pure fungus strains. Through morphological observation, we can classify them more correctly, so as to accurately understand the diversity of culturable fungi in Laolongkou Daqu and lay a foundation for the effective development and utilization of fungus resources. In view of the public demand and consumer market, Luzhou-flavor liquor still occupies a large share, has a vast development space, and has far-reaching significance for research.
