Model of associative symbiosis of bacteria of the genus Azospirillum with microalgae

摘要

We developed an express—method of the formation process study of associative symbiosis of bacteria of the genus Azospirillum, which can be observed by light microscopy during in situ experiment. Chlorella sorokiniana were used as higher plants. During 2 hours incubation of bacteria Azospirillum brasilense UZ A13-6 with Chlorella sorokiniana gradual formation of bacterial associations with microalgae was revealed. During eight-hour incubation, we have found that the bacteria cells have accumulated around microalgae cells, forming associative symbiosis with microalgae.
