ABSTRACT
Chlorella vulgaris is an edible microalgae and a highly notorious potential feed resource for many agriculturally important animal species. Chlorella vulgaris intake has also been linked to improvements in animal health and welfare. Its influence over animal development stems from its nutritive and protein-rich composition, thus leading to an increased commercial production to meet consumer demand. The aim of this work is to isolate and identify microalgae used in poultry farming and objectives of this research work is to determine the growth condition of microalgae and harvest microalgae used in poultry farming. Centrifugation of the sample to concentration the algal cells and plating using pour plate method was done. One percent agar-agar BG-11 medium was used for the algae isolation. Antibiotic added to avoid bacterial growth. Microscopic identification of the isolates based on cell morphology and colonial characteristics was carried out. The isolate was cultivated in a sterile BG-11 medium in presence of light and carbon dioxide and BG-11 medium as source of nutrient. Harvesting of chlorella vulgaris involves filtration, centrifugation and drying using hot oven at appropriate temperature. This study was able to isolate and identify the microalgae of interest, which can later be used in poultry farming in future study.
