Mutative rule of bacteria during the ferment from pollen to bee bread
蜂粮酿制过程中细菌的变化规律

Bacterial colonies cultivated on nutrient agar, improved "LB", MRS (4 5) and MRS (6 5) culture medium from the following samples of tea ( Camellia sinensis ) floral pollen collected by hand, corbicular pollen from pollen traps placed on colonies of honey bees ( Apis mellifera) in the tea yard and bee bread stored in comb cells for different time, were counted and analyzed The amount of bacterial colonies cultivated on the culture medium of MRS (4 5) and MRS (6 5) from bee bread of beginning ferment was predominant, then decreased rapidly with time of ferment The amount of bacterial colonies cultivated on the culture medium of improved "LB" from 5 day, 10 day, 15 day, 21 day bee bread was in the ascendant The amount of bacterial colonies cultivated on the culture medium of nutrient agar from 60 day bee bread was predominant
