SUBSTANTIATION OF USING CHLORELLA GENUS MICROALGAE AS A RAW MATERIAL FOR PREPARATION OF CHEMOPREVENTIVE SUBSTANCESAbstract
The purpose of this study was to substantiate the use of suspension of Chlorella genus microalgae as the most valuable raw material for preparation of carotene and chlorophyll а. The method is proposed for ultrasonication of Chlorella vulgaris microalgae suspension in order to increase availability of biologically active substances and improve microbiological performance of the prepared product. Before and after ultrasonication of samples, we determined the content of chlorophylls (a, b, c) and carotenoids using the spectrophotometric method, the level of total bacterial contamination using the method of limiting dilutions on MacConkey agar and microscopic study of microalgae and bacteria cell viability. It has been established that the ultrasonification method at wave amplitude 16 µm allows to transfer pigments into the water phase, inhibit viability of bacteria and obtain homogenisate of the Chlorella vulgaris microalgae suspension with preservation of carotenoids and green chlorophyll а. Thus, combined use of ultrasonication and parallel plating on MacConkey agar seems to be promising in view of preparation and quality control of axenic concentrate of Chlorella vulgaris microalgae, which can be used for preparation of chemopreventive pharmaceuticals.
