Bioenergy derived from biomass plays a more and more significant role in today’s energy supply system due to its renewability and sustainability. Biomass is the term referring to the material that we harness from organisms to use as biofuel, as well as the social, technical, scientific and economic fields benefited by biological sources. The wide distribution of biomass provides rich sources of energy generating raw materials. Exploiting clean and renewable microbial sourced energy is a particularly promising approach, which is efficient and eco-friendly in producing biofuel, heat and electricity via various routes including thermo-chemical, biological, and bio-electrochemical processes. Remarkable development in bioenergy conversion techniques – especially metabolic engineering and synthetic biology have brought a brighter future when facing non-renewable energy resource dwindling and climate change appearing severer day by day, by means of which we can produce a variety of biofuels from possible substrates to meet energy needs.
In order to address the issues of environmental sustenance and offer economical energy supply, we gladly provide production and utilization service of these promising microbial generated fuels and energy:
• Microbial oil: microbial oil is a triglyceride produced by microbes, and is similar to other kinds of biodiesels such as vegetable oil and animal fat-based diesel consisting of long-chain alkyl, which can be used in standard diesel engines. Some species of yeast are able to convert substrates into lipids.
• Ethanol fermentation: a microbial process which converts sugars into ethanol and carbon dioxide in the absence of oxygen, which takes place in yeast (e.g. Saccharomyces cerevisiae, chizosaccharomyces and some bacteria (e.g. Zymomonas mobilis).
• Biogas: a mixture of gases produced by produced by methanogen or anaerobic organisms in the absence of oxygen, which is usually produced from raw materials such as agricultural, food and municipal waste.
• Hydrogen production: a wide variety of waste and low-value materials such as agricultural waste can be utilized to produce hydrogen via biochemical pathways - dark and photo fermentation processes. Dark fermentation process involves strict anaerobe and facultative anaerobe bacteria converting carbohydrates to hydrogen by fermentation, besides hydrogen, sugars are converted to volatile fatty acids and alcohols as by-products. While photo fermentation process only proceeds in the presence of light, the conversion of hydrogen from fatty acids by Rhodobacter sphaeroides is a good example.
• Microbial fuel cells: in microbial fuel cells (MFCs) microbial fuel cells, microbes such as Geobacteraceae sulfurreducens, Shewanella oneidensis MR-1 and Escherichia coli catalyze electrochemical oxidations or reductions at an anode or cathode respectively, to convert chemical to electric current derectly. MFCs have a promising prospect due to the features of no pollution, high efficiency and mild reaction conditions.
By combining the advanced genetic tools with optimal screening techniques, Microbiosci can assist you to reprogram microbes and create mutations with high commercial value – optimizing strains to ensure their sustainability, maximize converting efﬁciency and minimize costs.
