(Culture of Chorella ellipsoidea S-1 in plastic bags)

Abstract

Chlorella ellipsoidea S-l was cultivated in transparent polietylene bags with continuous aeration of 1 liter of air per minute for each bag, under permanent illumination of aproximately 4,000 lux, at laboratory. At the 5^th day a total of 14.5 million of cell/mL was obtained. The best average production was between the 3^rd and 5^th days. The initial density of 10⁵ cell/mL or 10⁶ cells/mL had no influence in the total quantity of cells after the 4^th day. Cultures of smaller initial density (10⁵ cells/mL) had shown a better specific growth rate (µ = 2.2).
