Bioconversion of synthesis gas to second generation biofuels: A review

Trash to treasure: production of biofuels and commodity chemicals via syngas fermenting microorganisms

“…rods, cocci, or spirochetes), have a wide range of optimal growth temperatures (psychrophilic, mesophilic, or thermophilic), and demonstrate different tolerance toward molecular oxygen [13]. Syngas fermenting microorganisms also have diverse metabolic capabilities, resulting in the formation of a variety of native products such as acetate, ethanol, butanol, butyrate, formate, H 2 , H 2 S, and traces of methane [10,11,[13][14][15]. Though some methanogens are known to synthesize multi-carbon organics from syngas, the vast majority of syngas fermenting organisms are acetogens ( Figure 1).…”

“…Shown is the taxonomic classification of the genera capable of converting syngas to multi-carbon compounds based on organisms found in [10,11,[13][14][15]. With the exception of two archaeal genera, all of the genera that produce multi-carbon organic compounds are considered acetogens.…”

Edible oil mill effluent; a low-cost source for economizing biodiesel production: Electrospun nanofibrous coalescing filtration approach

“…A biofuel is a fuel that is produced from living organism, or more specifically made through biomass conversion (Mohammadi et al, 2011;Long et al, 2013). Biomass refers to recently living organisms, most often plants or plant-derived materials or even algae (Chisti and Yan, 2011;Bridgwater, 2012).…”

A review of conversion processes for bioethanol production with a focus on syngas fermentation

“…Among the different anaerobes, acetogens have been of prime interest due to their ability to grow chemolithotrophically (i.e., use inorganic reduced compounds as energy source) and produce ethanol and butanol along with acetate and butyrate from CO, CO2, H2, formate, and methanol (Mohammadi et al, 2011).…”
