Results and discussion Results for biomass production (figure 1) shown that culture times no larger than 4 days coupled with larger exchange of culture media will improve biomass concentration up to 10 g/L (productivity of 2 g/L*d-1), these results agree with those reported by Hong et al (2011) and Lee Chang et al (2013) where high initial concentrations of glucose boost biomass and lipid production durign the first 49 hr; however, substrate glucose levels as high as 100 g/L resulted in the retardation of biomass production in Aurantiochytrium strains (Yaguchi et al. 1997; Wong et al. 2008).	cache/cet-3092.pdf	txt/cet-3092.txt
