METHOD OF PRODUCTION OF BIOMASS OF PHOTOAUTOTROPHIC MICROORGANISMS Russian patent published in 2016 - IPC C12N1/12 C12Q3/00 C12M1/36 

FIELD: biotechnologies.

SUBSTANCE: method of production of a biomass of photoautotrophic microorganisms is offered. The method includes the preparation of liquid inoculum in an inoculator at continuous lighting and aeration by carbon dioxide with the subsequent supply of the obtained culture into the fermenter. Cultivation of the biomass in the fermenter is performed with the film-size flow of liquid in transparent tubes with simultaneous lighting by a lamp and aeration by carbon dioxide and supply of the ready culture of microorganisms into the ready culture collector. From the collector the biomass is supplied to the spray dryer where it is dried by warm air and the ready-made product is obtained in a powdery form with the content of solids of 95…97%.

EFFECT: increase of the yield of the biomass, decrease of specific energy consumption, ensuring ecological safety, improvement of quality and increase of periods of storage of the finished product.
