Using poultry farms wastewater to increase Arthrospira platensis (Nordst.) Geitler productivity
The possibility of microalgae Arthrospira platensis growing on mineral-organic medium, which consists of Zarrouk standard medium and chicken dung extract, has been investigated. The optimal balance of nutrient medium by the component composition of nutrients for A. platensis growing has been determined. The graphs representing results of the experiments have been built and the basic characteristics of growth of culture A. platensis have been calculated by approximating of the linear growth phase. Dependence of the A. platensis growth kinetic characteristics from chicken dung extracts concentrations in the nutrient medium has been determined. It has been found that A. platensis must be adapted to new culture conditions for intensive growth on the organic-mineral nutrient medium. Quantitative estimation of microalgae growth and productivity depending on culture conditions, in this case — from the composition of the nutrient medium, has been given, and it is shown that the productivity of culture was 1.6 times higher during cultivation on a nutrient medium with 15 % extract from chicken dung than in Zarrouk standard medium.
