microbial oil has high similarity to the oil obtained from plants and animals. they are renewable sources that can be used for different purposes such as production of biofuels. biofuels are renewable, biodegradable, and nontoxic, which makes them highly environmentally friendly. producing oil from yeasts has more advantages than that from plants. accordingly, isolation of oleaginous yeasts wit...

micro-organisms such as bacteria, yeasts, molds and algae that accumulate lipid more than 20% of their biomass are called oleaginous. microbial lipid has a lot of similarity to the oil obtained from plants and animals. microbial lipids are renewable sources that can use for different purposes such as biodiesel production. production of oil from yeasts has more advantages than plant’s oil. accor...

microbial lipids have a great similarity to the lipids obtained from plants and animals. triacylglycerol is the storage lipid in most of eukaryotic cells; this characteristic attracts a lot of attention for using these lipid sources in biodiesel production. accumulation of neutral lipid composed of triacylglycerol and sterylster is an induced response to environmental stresses in many living or...

BACKGROUND Microbial lipid production by using lignocellulosic biomass as the feedstock holds a great promise for biodiesel production and biorefinery. This usually involves hydrolysis of biomass into sugar-rich hydrolysates, which are then used by oleaginous microorganisms as the carbon and energy sources to produce lipids. However, the costs of microbial lipids remain prohibitively high for c...

Microbial communities (microbiomes) are associated with almost all metazoans, including the honey bee Apis mellifera. Honey bees are social insects, maintaining complex hive systems composed of a variety of integral components including bees, comb, propolis, honey, and stored pollen. Given that the different components within hives can be physically separated and are nutritionally variable, we ...

Silver carp fillets were treated with liposomal encapsulated and unencapsulated pomegranate peel extract at 0.5 and 1% w/w to evaluate the effect of the extracts on the shelf life of the fillets during 15 days of refrigerated storage. Quality changes of the samples were investigated in terms of total volatile basic nitrogen (TVB-N), peroxide value (PV), thiobarbituric acid (TBA) and microbial c...

Microbial lipids hold great promise as biofuel precursors, and research efforts to convert such renewable diesel fuels have been increasing in recent years. In contrast the numerous literature reviews on growing, characterising extracting from oleaginous microbes, converting vegetable oils hydrocarbon fuels, this review aims provide insight into aspects that are specific hydroprocessing microbi...

Soil microbial community structure is clearly linked to current plant species composition, but less is known about the legacy effects of plant species and agricultural management practices on soil microbial communities. Using microbial lipid biomarkers, we assessed patterns of community-level diversity and abundance at depths of 0-10 and 10-25 cm from three hay (alfalfa/orchardgrass) and two co...

Microbial lipid production from oleaginous yeasts is a promising process for the sustainable development of microbial biodiesel industry. However, feedstock cost poses an economic problem biodiesel. After extraction, yeast biomass can be used as organic source production. In this study, volatile fatty acids (VFAs), produced via anaerobic digestion lipid-extracted (LEY) residue, were utilized ca...

BACKGROUND Acetic acid is routinely generated during lignocelluloses degradation, syngas fermentation, dark hydrogen fermentation and other anaerobic bioprocesses. Acetate stream is commonly regarded as a by-product and detrimental to microbial cell growth. Conversion of acetate into lipids by oleaginous yeasts may be a good choice to turn the by-product into treasure. RESULTS Ten well-known ...
