“…However, the yields of these compounds were lower than those found on the oatmeal-based medium, probably because the digestion of cellulose is rate limiting. Increases in the yields of these products may be enhanced by new developments in fermentation technology, membrane technologies and genetic manipulation (Danner & Braun, 1999). Of some concern, however, is an anomaly in the production of hydrocarbons by G. roseum.…”

An endophytic fungus, Gliocladium roseum (NRRL 50072), produced a series of volatile hydrocarbons and hydrocarbon derivatives on an oatmeal-based agar under microaerophilic conditions as analysed by solid-phase micro-extraction (SPME)-GC/MS. As an example, this organism produced an extensive series of the acetic acid esters of straight-chained alkanes including those of pentyl, hexyl, heptyl, octyl, sec-octyl and decyl alcohols. Other hydrocarbons were also produced by this organism, including undecane, 2,6-dimethyl; decane, 3,3,5-trimethyl; cyclohexene, 4-methyl; decane, 3,3,6-trimethyl; and undecane, 4,4-dimethyl. Volatile hydrocarbons were also produced on a cellulose-based medium, including heptane, octane, benzene, and some branched hydrocarbons. An extract of the host plant, Eucryphia cordifolia (ulmo), supported the growth and hydrocarbon production of this fungus. Quantification of volatile organic compounds, as measured by proton transfer mass spectrometry (PTR-MS), indicated a level of organic substances in the order of 80 p.p.m.v. (parts per million by volume) in the air space above the oatmeal agar medium in an 18 day old culture. Scaling the PTR-MS profile the acetic acid heptyl ester was quantified (at 500 p.p.b.v.) and subsequently the amount of each compound in the GC/MS profile could be estimated; all yielded a total value of about 4.0 p.p.m.v. The hydrocarbon profile of G. roseum contains a number of compounds normally associated with diesel fuel and so the volatiles of this fungus have been dubbed 'myco-diesel'. Extraction of liquid cultures of the fungus revealed the presence of numerous fatty acids and other lipids. All of these findings have implications in energy production and utilization.

“…Recently, there has been growing interest in utilization of biocatalysts to convert renewable resources into chemicals, due to high yield and selectivity, and fewer byproducts. However, because of the metabolic restriction in microorganisms, only a few bulk products currently are produced via fermentation [8]. Therefore, development of new technologies to broaden the product spectrum is necessary.…”

“…Recombinant DNA technology is used to clone and manipulate gene encoding enzymes in organisms. Recombinant microorganisms, with altered sugar metabolism, are able to ferment sugar to some specialty chemicals, which cannot be produced by the corresponding original stain [8]. For example, catechol and adipic acid were produced from glucose using genetically modified Escherichia coli.…”

Abstract:Recently, utilization of renewable resources to replace petroleum as a primary feedstock for liquid fuels, chemicals and materials has become a topic of interest around the world. It is intriguing due to rising oil prices, the negative effects of petroleum on the environment and the advantages of renewable resources, such as their abundance and sustainability. Herein, the possibilities for biobased chemicals prepared from renewable resources are reviewed. The most popular feedstocks for commodity and specialty chemicals are carbohydrates as they account for approximately 95% of the biomass produced annually. The conversion routes, including chemical and biological routes, direct extraction, and selected technical advancements are discussed. Examples of select biochemcials, their conversion pathways from biomass, and their derivatives and potential applications are indentified.

“…During the early twentieth century, the primary method of butanol production was anaerobic fermentation with Clostridium acetobutylicum to produce a mixture of acetone, butanol, and ethanol. The butanol yields were low, and as oil prices declined after World War II, petrochemical routes to butanol displaced the fermentation route (50). The primary petrochemical route used today involves the hydrogenation of n-butyraldehyde (49), and production costs hover around $0.66/kg (24).…”

Approximately 89 million metric t of organic chemicals and lubricants, the majority of which are fossil based, are produced annually in the United States. The development of new industrial bioproducts, for production in standalone facilities or biorefineries, has the potential to reduce our dependence on imported oil and improve energy security. Advances in biotechnology are enabling the optimization of feedstock composition and agronomic characteristics and the development of new and improved fermentation organisms for conversion of biomass to new end products or intermediates. This article reviews recent biotechnology efforts to develop new industrial bioproducts and improve renewable feedstocks and key market opportunities.
