Growth and Metabolite Production of Chroococcus minutus Under Different Temperature and Light Conditions

Cyanobacteria consisting of valuable bioactive compounds reveal the pharmaceutical and biological activities. In this work, the sample was collected from freshwater and was isolated under inverted microscope. Identification was carried out by morphologically. The isolated Chroococcus minutus was cultivated in Bristol nutrient medium. Growth and norharmane production of Chroococcus minutus under temperature and light conditions were presented. The most norharmane production and the cell numbers were observed at 35 °C and irradiation of 1896 lux as 4.017 µg/g and 154.3 µg/g respectively.
