Microalgae based biofuels are getting attention due to energy crisis and enviromental protection. In the present study, the Chlorella sp. was cultivated in BG-11 medium at batch mode. The effect of different nitrogen (sodium nitrate, potassium nitrate and urea) and organic carbon (glucose, glycerol and sucrose) sources were analyzed on growth and lipid accumulation on this species. The highest ...

Accumulation of lipid reserves is considered important for the overwinter survival many animals. Fish are thought to deplete lipids until they reach a critical minimum below which starvation mortality occurs, meaning that lipid-dependent selective may be strong pressure leading life-history evolution favouring accumulation and storage. Much our current knowledge comes from either laboratory stu...

Eight-month-old Sprague-Dawley rats were fed on diets containing dietary fiber at the 5% level for 3 weeks to examine the effect on the lipid metabolism and immune function. Among cellulose, guar gum, partially hydrolyzed guar gum (PHGG), glucomannan and highly methoxylated pectin, guar gum induced a significant decrease in the food intake and weight gain, as well as a significant increase in t...

Biodiesel production was examined with Scenedesmus obliquus in a recirculatory aquaculture system with fish pond discharge and poultry litter to couple with waste treatment. Lipid productivity of 14,400 liter ha(-1) year(-1) was projected with 11 cultivation cycles per year. The fuel properties of the biodiesel produced adhered to Indian and international standards.

Microalgae are emerging as the sustainable key source of green fuels and neutraceuticals. In the current study, a strain of Chlorella pyrenoidosa was isolated, identified and biochemically analyzed. Studies were undertaken to enhance its biomass and lipid productivities for sustainable biodiesel production. Growth was monitored in BG11, BBM, Bristol and Fogg’s medium as cell count, O.D, PCV and...

Phytoplankton have great potential for biodiesel production and offer promises opportunities in the long term. species reach higher growth rates, thus productivity, than conventional forestry or agricultural crops other aquatic plants. The oil yield phytoplankton is an order of magnitude larger terrestrial oleaginous crops. To meet phytoplankton-based there a need to radically increase lipid yi...

Large-scale microalgae cultivation for biofuel production is currently limited by the possibility of maintaining high yield and lipid content, concomitantly. In this study, physiological changes Chlorella vulgaris NIES 227 during accumulation under nutrient limitation was monitored in parallel with photosynthetic capacity to fix carbon from proxy oxygen productivity. exponential growth phase, a...

Bioprocess limitations imposed by microbial cell-to-cell phenotypic diversity remain poorly understood. To address this, we investigated the origins of such culture diversity during lipid production and assessed the impact of the fermentation microenvironment. We measured the single-cell lipid production dynamics in a time-invariant microfluidic environment and discovered that production is not...

The genus Chlorella is a widely employed microalga for biodiesel, as it can be grown using photo/mixo/heterotrophic mode of cultivation. The present investigation was undertaken with the hypothesis that addition of different substrates (amino acids, carbon sources, vitamins) along with reducing agents may aid in diverting Acetyl CoA to malonyl CoA or fatty acid biosynthesis, under mixotrophic c...

As a replacement to existing fossil fuels, biofuels, have proven their worth; however, their widespread use is limited due to inconsistent yields, higher costs and poor productivity. An oleaginous yeast, Rhodosporidium toruloides has been reported to accumulate substantial amounts of lipids (that can be converted to biofuels) and therefore, it was selected for study and optimization. Apart from...
