Growth of aphanothece microscopica nägeli on exogenous sugars
AbstractBiological processes for wastewater treatment generally produce a lot of biomass or active sludge without reuse. In this context, incorporation of organic matter and nutrients from agro industrial effluents into cell mass for single-cell protein allowed application of sustainable process. Cyanobacteria could be used due to its versatile metabolism. So, the aim of this paper was evaluate the growth of cyanobacteria Aphanothece microscopica Nägeli growth on heterotrophic medium with glucose, lactose and sucrose. Growth curves indicated that cultivation of cyanobaterial on the dark depend the type of carbon source and there are different mechanisms for glucose, fructose and sucrose consumption. Results suggest a useful application of cyanobacteria on organic matter removal from wastewater.
