This invention relates to the field of
fungal strain cultivation technology, and particularly to a method for isolating and cultivating fungal strains from
matsutake fruiting bodies. The method involves collecting
matsutake mushrooms that are 70%–80% mature and free from insects, disinfecting them with
alcohol, longitudinally splitting them in half, removing the
flesh from the cap and stipe, and inoculating them onto a slant culture medium to obtain a primary strain. This primary strain is then inoculated into a culture medium and shaken to obtain a primary
shake flask strain, which is then inoculated into a culture medium. The strain is then shaken and cultured, and the concentration of metabolites, dissolved
oxygen, and pH in the culture medium are collected in real time to construct a strain
growth time prediction model to predict the stage culture duration. The
cell proliferation trend is determined based on the number of
matsutake mycelial cells. Based on a comparison of the actual culture time during the initial adjustment period and the stage culture time, the adjustment method for the
logarithmic growth phase of the current batch is determined. Based on a comparison of the
shake flask culture time and the predicted culture time, the adjustment method for the initial culture conditions of the next batch is determined. This invention effectively optimizes
shake flask culture conditions and improves strain quality.
