Abstract
The current study aimed to evaluate if the addition of pentoses along with variations in light intensity and photoperiod can stimulate the production of polyhydroxybutyrate (PHB) and other biomolecules by Chlorella fusca LEB 111. The variables evaluated were the addition of xylose and arabinose as sources of organic carbon, different photoperiods (18â¯h, 12â¯h and 6â¯h light) and variations in light intensities (58, 28 and 9â¯Î¼molphotonsâ¯mâ2â¯sâ1). The highest PHB accumulation (17.4%â¯wâ¯wâ1) and protein production (53.2% wwâ1) were observed in assays with xylose addition and a photoperiod of 6â¯h of light provided at 28 and 58â¯Î¼molphotonsâ¯mâ2â¯sâ1, respectively. The highest lipid content (24.7%â¯wâ¯wâ1) was obtained with 18â¯h of light. The current study contributes to the development of sustainable alternatives for the use of wastes and the production of biomolecules from algae.
