Health aspects of Microalgae Cultivation
The aim is to analyze some sources of microbial contamination in the cultivation of microalgae and to evaluate possible ways of monitoring. Materials and methods. The water used by the city distribution network from the Urals open water intake, as well as from the artesian well from a depth of 120 m, was used in the work. The water quality was evaluated by the bacteriological method in accordance with Sanitary and Epidemiological Station 2.1.4.1074-01. Results. Data are presented showing the presence of autochthonous microflora in water and artesian water, represented by bacteria, microalgae and protista, capable of causing the cultivated microalgae culture contamination. A comparative assessment of water quality makes us opt for a closed water source. To monitor sanitary quality throughout the enterprise, the sanitary control of the water used and the biomass grown should be included. Conclusion. For the purposes of epidemiological safety, it is necessary to monitor the sanitary quality of microalgae biomass. Microbiological approaches with technologies based on the use of ready plasticized nutrient media, can effectively monitor the quality of the water used, as well as the products produced.
