Species of various filamentous fungus taxa were tested for ability to produce lipids suitable as a material for manufacturing biodiesel. The mucoralean fungus Cunninghamella japonica was found to be a promising lipid producer. The inexpensive medium for its growth developed in this study contained ammonium nitrate as a nitrogen source. With its use, up to 16 g/l biomass and over 7 g/l lipids was obtained. The fungal lipids were dominated by oleic acid. It constituted 50% of total fatty acids… 
Biodiesel fuel production from lipids of filamentous fungi
An ecologically friendly method for extracting lipids from fungal mycelia, utilizing supercritical technologies, has been used and a correlation between the lipid content in the spore inoculum and the maximal lipidcontent in biomass has been discovered.
Lipid extraction from the biomass of Trichoderma koningiopsis MX1 produced in a non-stirring culture for potential biodiesel production
Results show that fungal cultural conditions and the lipid extraction technique are determinants for producing biodiesel from fungal lipids and modification of some of these conditions could increase their efficiency and viability.
Production of fatty acid methyl esters that are the basis for biodiesel fuel from mycelial fungi lipids extracted by supercritical CO2
Lipids are produced with a 60 wt % yield in terms of dry biomass in the course of fermentation of oleaginous fungi at 27–28°C for 4–5 days. Triglycerides are extracted by supercritical carbon dioxide
Value-added oil and animal feed production from corn-ethanol stillage using the oleaginous fungus Mucor circinelloides.
This study highlights the potential of oleaginous fungus, Mucor circinelloides in adsorbing/assimilating oil and nutrients in thin stillage (TS), and producing lipid and protein-rich fungal biomass.
Influence of lignin and oxygen on the growth and the lipid formation of the fungus Lentinus tigrinus
Changes in the composition of neutral lipids, such as variation in the ratio of esterified and free sterols, have occurred; thus, the amount of sterol esters reduced simultaneously with a decrease in the content of free fatty acids.
Lipid, protein and fatty acid profiles of Emericella sp. in different media
The soil-derived fungus Emericella sp. was explored for its potential to produce lipid. Lipid profile, fatty acid composition, production of proteins and carbohydrates from lipid-extracted biomass
Biodiesel production from Egyptian isolate Fusarium oxysporum NRC2017
BackgroundBiodiesel is a long chain of fatty acid alkyl esters derived from renewable feedstock and it was used as a partial or full substitute for petrol diesel.ResultsAmong 36 Egyptian filamentous
Antioxidant Effect on the Growth And Formation of Lipids in the Fungus Lentinus tigrinus Growing on Medium with Lignosulfonate
The addition of an antioxidant (2-ethyl-6-methyl-3-hydroxypyridine hydrochloride) to a culture of the fungus Lentinus tigrinus growing on a medium with lignosulfonate inhibited growth and changed the
Fungal-assisted algal flocculation: application in wastewater treatment and biofuel production
Fungal-assistedmicroalgal flocculation shows significant potential for solving the major challenges facing the commercialization of microalgal biotechnology, namely the efficient and cost-effective harvesting of freshwater and seawater algal strains and enhancement of total oil production and optimization of its composition.
Polysaccharides from mycelium of the fungus Cunninghamella japonica
The presence of this polysaccharide, as well as a low content of chitosan and polyuronides, distinguishes the studied strain C. japonica from most of the known Mucorales.


Production of methyl ester fuel from microalgae
Microalgae are unique photosynthetic organisms that are known to accumulate storage lipids in large quantitites and thrive in saline waters. Before these storage lipids can be used, they must be
Biodiesel production by direct methanolysis of oleaginous microbial biomass
Biodiesel is a renewable fuel conventionally prepared by transesterification of pre-extracted vegetable oils and animal fats of all resources with methanol, catalyzed by strong acids or bases. This
Biodiesel generation from oleaginous yeast Rhodotorula glutinis with xylose assimilating capacity
Chemical analysis indicated that biodiesel obtained by transesterification possessed similar composition to that from vegetable oil, one of the widely used feedstock for biodiesel.
Biodiesel production from heterotrophic microalgal oil.
The results suggested that the new process, which combined bioengineering and transesterification, was a feasible and effective method for the production of high quality biodiesel from microalgal oil.

As demonstrated here, microalgae appear to be the only source of renewable biodiesel that is capable of meeting the global demand for transport fuels.
Microdiesel: Escherichia coli engineered for fuel production.
Biodiesel-adequate FAEEs are established, referred to as Microdiesel, in metabolically engineered Escherichia coli by employing engineered micro-organisms, enabling a broader use of biodiesel-like fuels in the future.
Synthesis of poly-3-hydroxyalkanoates is a common feature of fluorescent pseudomonads
While the fluorescent pseudomonads are characterized by their inability to make PHB, they appear to share the capacity to produce PHAs, which may be useful in the optimization of PHA production for biopolymer applications.

Biodiesel: Source, Production, Composition, Properties and Its Benefits
Biodiesel is an eco-friendly, alternative diesel fuel prepared from domestic renewable resources i.e. vegetable oils (edible or non-edible oil) and animal fats, that runs in diesel engines-cars,
A simple method for the isolation and purification of total lipides from animal tissues.
A simplified version of the method for the preparation and purification of brain lipides has the advantage of being simpler, of being applicable to any scale desired, of substantially decreasing the losses of lipides incidental to the washing process, and of yielding a washed extract which can be taken to dryness without foaming and without splitting of the proteolipides.
