New Hampshire cellulosic ethanol producer Mascoma Corp. has reportedly filed a form with the U.S. Securities and Exchange Commission about its proposed initial public offering (IPO) of common stock shares. According to news sources, the company hopes to raise $100 million through the IPO to further develop its production process, which involves creating enzymes from genetically modified yeast and bacteria to break down plant sugars and convert them into ethanol. By combining enzymatic digestion with fermentation, the process is apparently less expensive than other manufacturing methods. The new funding would also be used to expand the company’s marketing and to build manufacturing plants that would convert wood into ethanol. See Bloomberg, September 16, 2011; Mascoma Corp.
