Produção, purificação, caracterização e aplicação do biossurfactante produzido por rhodotorula mucilaginosa de ambiente antártico
The production of biosurfactants, comes from microorganisms that are biodegradable, biocompatible and have low toxicity. It was also observed that are stable under extreme conditions such as varying pH, temperature and salinity. The Antarctic environment has a huge diversity of well-adapted microorg...

The production of biosurfactants, comes from microorganisms that are biodegradable, biocompatible and have low toxicity. It was also observed that are stable under extreme conditions such as varying pH, temperature and salinity. The Antarctic environment has a huge diversity of well-adapted microorganisms. Their use as a source of stable bioproducts technology is opening up a new market that aims to isolate them and search that can be useful. The importance for the expansion of bioproducts is to reduce production costs and improving the utilization of biomass, especially the pineapple waste (Ananas comosus). This paper reports the evaluation of biosurfactant production by Rhodotorula mucilaginosa yeast isolated encoded Antarctica as L69. For yeast cultivation, YPD medium was used for pre inoculum, which was incubated for 72 hours at 15°C and 120 rpm. For the inoculum, the modified YPD medium with the best components analyzed for carbon and nitrogen source (pineapple extract, yeast extract, peptone and ammonium sulfate) were incubated for 24 hours at 15°C and 120 rpm was used.
