3. DISCUSSIONS 3.1. Biofuel Production in Faster and Cheaper Way.
As we review, the prospects of using yeasts and microalgae as sources of cheap oils that can be used for biodiesel. We conclude that yeast oils, the cheapest of the oils producible by heterotrophic microorganisms, are too expensive to be viable alternatives to the major commodity plant oils. Algal oils are similarly unlikely to be economic; the cheapest form of cultivation is in open ponds, which then requires a robust, fast-growing alga that can withstand contaminating bacteria and protozoa and gain an oil content of at least 40% of the biomass. No such alga has identified yet. However, if the prices of the major plant oils and crude oil continue to rise in the future, just …show more content…
This produces ethanol. In fermentation, naturally occurring yeast on the pinot noir grapes, are responsible for the production of the biofuel. They eat all the sugar they could which creates fermentation. Carbon dioxide, the unwanted inorganic carbon, released.
Microbes like yeast are able to produce biofuel but the process is not very easy. It takes plenty of time (say a month), its expensive on a large scale, and there are also ethical issues. 3.3. Yeast Tolerance Level.
Yeasts used to convert corn and other plant remains into biofuels such as ethanol. However, large concentrations of ethanol are toxic to yeast, which limits the production capacity of many yeast strains used in industry.
The standard process of making biofuels involves using yeast (a type of fungus) and proceeds in two steps. First, enzymes degrade plant material into sugar. Then, yeast transforms the sugar to ethanol. The plant matter converts directly to hydrocarbons in a single step.

FUTURE PROSPECTS Most life-cycle studies of biofuels have found that bio-ethanol made from corn or sugarcane generally reduces greenhouse gases, replacing gasoline [2]. Biofuels have been increasingly explored as a possible alternative source to gasoline with respect mainly to transport. 4.1 Global Biofuel Production
Global biofuel (bioethanol and biodiesel) production tripled from 4.8 billion gallons in 2002 to 16.0 billion in 2007, but still accounts for less than 3% of the global transportation fuel supply. To summarise, interest in biofuels is increasing for a number of reasons: a) Reduced reliance on fossil fuels; b) Reduction in greenhouse gas emission; c) National independent security of fuel supply;
4.2 Employment and economic benefits through the development of a new fuel production. Biofuels Production, Investment Location & Subsidy Regime Biofuels can be ether wholly or partially substituted for petrol or diesel. Bioethanol is mainly made from starch or sugar crops (such as wheat, corn, sugarcane). It can be used as a 5% blend with petrol. This blend requires no engine modification, but higher proportions of ethanol only can be used with engine
