Embodiment
[0024] One, the preparation method of Aspergillus GLHZB319 bacterial strain is:
[0025] Take 1.00g of soil with fallen leaves, add it to a triangular flask filled with 25mL of sterile water, shake it for 1min, and make the soil evenly dispersed to obtain a soil suspension; absorb 4 drops of the soil suspension, and drop it on the single chlorophyll extracted with 80% acetone On the plate medium prepared with agar, spread evenly with a coating ring, and check the plate culture results after 3 days of constant temperature cultivation at 30°C; the strains that can grow on the plate and produce transparent circles will be extracted by a single strain extracted in 80% acetone The fermentation effect in the chlorophyll aqueous solution was further confirmed. The fermentation conditions were: temperature 30°C, natural pH, rotation speed 100r / min. Aspergillus GLHZB319 strain had the best fermentation effect.
[0026] Characteristics of Aspergillus GLHZB319 strain: The colonies on pot...
