Oleaginous microorganisms have emerged as potential sources of oils for biodiesel production. To replenish as an alternative to the vegetable oils, higher lipid accumulating strain coupled with process optimization is indispensable. In the present study, response surface methodology (RSM) based central composite design (CCD) was used for optimization of lipid content from oleaginous fungus Aspe...

This study focuses on the cell growth and the neutral lipid production modeling of Chlamydomonas reinhardtii in terms of different ammonium concentrations. Autotrophy was maintained during growth in a double walled bioreactor, using Tris Phosphate (TP medium) with only CO(2) and NH(4)Cl as sole sources of carbon and nitrogen, respectively. Nitrogen depletion results in an increase in neutral li...

Fungi accumulate lipids in a manner dependent on the quantity and quality of the nitrogen source on which they are growing. In the oleaginous yeast Yarrowia lipolytica, growth on a complex source of nitrogen enables rapid growth and limited accumulation of neutral lipids, while growth on a simple nitrogen source promotes lipid accumulation in large lipid droplets. Here we examined the roles of ...

background: in recent years, many studies have been conducted on finding a suitable replacement for fish meal to supply the needs of aquaculture feed industry. objectives: the present study was performed to examine the effect of replacing fish meal and fish oil with plant sources on bacterial counts in intestinal contents and mucus and bacterial composition in beluga sturgeon. methods: beluga s...

objective: the effect of herbal medicine is more useful than synthetic medicines. the present research paper aims to show the effects of leaves extracts of zizyphus spina christi (zsc) on lipid profile, lipid peroxidation and activities of aminotransferase enzymes in streptozocin induced diabetic adult male rats. materials and methods: fifty six male rats weighing 150-200 gm were included in th...

Background The sustainability of microbial lipids production from traditional carbon sources, such as glucose or glycerol, is problematic given the high price of raw materials. Considerable efforts have been directed to minimize the cost and find new alternative carbon sources. Volatile fatty acids (VFAs) are especially attractive raw materials, because they can be produced from a variety of or...

The current scenario in renewable energy is focused on development of alternate and sustainable energy sources, amongst which microalgae stands as one of the promising feedstock for biofuel production. It is well known that microalgae generate much larger amounts of biofuels in a shorter time than other sources based on plant seeds. However, the greatest challenge in a transition to algae-based...
