“…In this case, the total lipids fraction as well as the neutral lipids, glycolipids + sphingolipids, and phospholipids fractions are mainly comprised of 16- and 18-carbon-chain fatty acids, predominantly oleic (C18:1), stearic (C18:0), palmitic (C16:0), and linoleic (C18:2) acid. The high content (59.4%) of saturated fatty acids lipids and the high cetane number related to them, is an indication that the lipids produced by C. laurentii 11 from cheese whey is suitable for the production of a biodiesel with excellent burning characteristics (Mittelbach and Remschmied (2004). …”

This study aimed the optimization of culture condition and composition for production of Cryptococcus laurentii 11 biomass and lipids in cheese whey medium supplemented with sugarcane molasses. The optimization of pH, fermentation time, and molasses concentration according to a full factorial statistical experimental design was followed by a Plackett-Burman experimental design, which was used to determine whether the supplementation of the culture medium by yeast extract and inorganic salts could provide a further enhancement of lipids production. The following conditions and composition of the culture medium were found to optimize biomass and lipids production: 360 h fermentation, 6.5 pH and supplementation of (g L−1): 50 molasses, 0.5 yeast extract, 4 KH2PO4, 1 Na2HPO4, 0.75 MgSO4·7H2O and 0.002 ZnSO4·H2O. Additional supplementation with inorganic salts and yeast extract was essential to optimize the production, in terms of product concentration and productivity, of neutral lipids by C. laurentii 11. Under this optimized condition, the production of total lipids increased by 133% in relation to control experiment (from 1.27 to 2.96 g L−1). The total lipids indicated a predominant (86%) presence of neutral lipids with high content of 16- and 18-carbon-chain saturated and monosaturated fatty acids. This class of lipids is considered especially suitable for the production of biodiesel.

“…Compared to methanol, ethanol has a lesser vapor pressure, enhanced water tolerance, a higher heating value and better solubility with hydrocarbon liquids, which makes ethanol fuels better than blended methanol fuels. It has been shown that the increased oxygen concentration of alcohols can result in a better complete and cleaner combustion and that this can also lower the temperature inside the combustion chamber 35,36 . Methanol has a greater oxygen concentration than ethanol (approximately 50 and 35 by weight, respectively, as shown in Figure 1).…”

In the coming years, energy sources will play a vital role in global development. Biofuels made from sustainable sources are essential for the global economy's long‐term viability and the reduction of greenhouse gas emissions. Clean, renewable, and sustainable must be the watchwords for future energy strategy. Alcohol fuels are again becoming a popular term in the context of green fuel usage in relation to climate change mitigation and clean fuel technology. In this review, low alcohol synthesis, applications and limitations as fuel and its catalytic conversion to fuel and petrochemicals were discussed, in addition to the techno‐economic evaluation, environmental implications and prospects for practical application of low alcohols as fuels and petrochemicals. The study shows that lower alcohols have emerged as a fundamental feedstock for the synthesis of fuels and value‐added chemicals due to the increased accessibility of conversion technologies in recent years, but the cost of producing lower alcohols affects their commercialization and availability.
