Enhanced lipidic algae biomass production using gas transfer from a fermentativ...

In order to produce single-cell oil for biodiesel, a yeast and a microalga were, for the first time, grown in two separate reactors connected by their gas-phases, taking advantage of their complementary nutritional metabolisms, i.e., respiration and photosynthesis. The yeast Rhodosporidium toruloides was used for lipid production, originating a carbon dioxideenriched outlet gas stream which in turn was used to ...

Biodiesel from heterotrophic and autotrophic microalgae: a sustainable producti...

Biodiesel from microalgae Chlorella protothecoides growing at autotrophic and h...

Biodiesel is an alternative energy to fossil fuels, and is produced from biomass, therefore provides lower CO2 emissions. Currently, biodiesel is produced from plant oils, animal fats and used oils. These sources are low-yield which is a limitation to the production of biodiesel in large quantities. On the contrary, microalgae present a very high yield and can be produced in large amounts. The bio-refinery of m...

Carotenoid and lipid production by the autotrophic microalga Chlorella protothe...

Today microalgae represent a viable alternative source for high-value products. The specie Chlorella protothecoides (Cp), heterotrophically grown, has been widely studied and provides a high amount of lutein and fatty acids (FA) and has a good profile for biodiesel production. This work studies carotenoid and FA production by autotrophic grown Cp. Cp was grown until the medium’s nitrogen was depleted, then dilu...

Diabetes mellitus auto-referido no Município de São Paulo: prevalência e desigu...

Constitui objetivo do presente trabalho a caracterização da prevalência do Diabetes Mellitus Auto-Referido (DMAR) no Município de São Paulo, obtida a partir do inquérito domiciliar realizado pelo Estudo Multicêntrico sobre a Prevalência do Diabetes no Brasil, de 1986 a 1988. A amostra foi composta por 2007 indivíduos de 30 a 69 anos de idade, de ambos os sexos, selecionados em três áreas de distintas condições ...
