Mascoma Corporation Raises $30 Million in Series B Funding
Mascoma Corporation, the leader in cellulosic biomass-to-ethanol development and
production, has raised $30 million in its second round of venture funding.
Today ethanol in the U.S. is made primarily from corn, a resource with multiple uses
with limits to its long term capacity. Ethanol made from cellulosic biomass (e.g. grass,
wood, and various agricultural and forestry wastes) takes advantage of significantly
lower raw material cost, more plentiful and varied feedstocks, and expands the potential
for ethanol to blend with and displace gasoline with a cleaner, renewable,
domestically-produced liquid fuel.
Converting cellulose to ethanol involves two fundamental steps of breaking the long
chains of cellulose molecules into glucose and other sugars, and then fermenting those
sugars into ethanol. In nature, these processes are performed by different organisms:
Fungi and bacteria that use enzymes called cellulases to ?free? the sugar in cellulose,
and Other microbes, primarily yeasts, that ferment sugars into alcohol
