PRODUCTIVITY OF MICROALGAE CHLORELLA VULGARIS IN LABORATORY CONDITION

Abstract

Algae biomass is increasingly regarded as a potential resource that could be used to produce biofuels, electricity and heat. Algae contain a lot of nutrients, so they can be used as food for humans and livestock. Because of their valuable composition (many nutrients) they are used as supplements of balanced diet, in turn taking into account their biosorption abbility they are used to detoxification of human body. Algae cultivation does not demand large areas of land to expose cells to sunlight, so their production rate is higher than vascular plants. Moreover algae cultivation lets to achieve high biomass concentration. Important cultivation factors are: illumination (light intensity is an important factor because it drives photosynthesis), CO2 supply, culture medium and mixing. The experimental research was conducted using Chlorella vulgaris BA 002 strain. The aim of this study was to determine the effectiveness of biomass growth in laboratory condition.
