Abstract

Glucose, sacarose, and sugarcane molasses were tested as substrates for production of biomass and phycobiliproteins by Nostoc sp., varying their concentrations in relation to a mineral medium, BG11. All substrates increased the biomass and phycobiliproteins when compared with the control. Sugarcane molasses showed to be the best substrate for production of both biomass and phycobiliproteins. Greater biomass production occurred in sugarcane molasses 1.0 g L^-1 and it was 5.7 times greater than the control. With glucose, it was in 2.5 g L^-1 and sucrose, in 1.5 g L^-1, reaching 2.5 and 4.8 times greater than the control, respectively. For phycobiliproteins, the major production was in sugarcane molasses 1.0 g L^-1, 12.5 times greater than the control. With glucose, it was in 1.0 g L-1 and sucrose, in 0,5 g L^-1, reaching 3.0 and 4.5 times greater than the control, respectively. The Nostoc sp. assayed can grow mixotrophically, using glucose, sucrose, and sugarcane molasses as organic substrates, and a greater production of biomass and phycobiliproteins can be reached when compared with the autotrophic growth.
