Microbial utilization of silviculture biomass

Several excellent reviews have been published on biomass production from forest ecosystems (32, 33), and data (Table 3) indicate that forestry remains and processing wastes are not fully utilized today. Chemical products that can be obtained from forestry biomass are ammonia, methanol, ethanol, fuel gas and oil, and charcoal. Ethanol fermentation by yeast from wood hydrolysis could become competitive within 10 to 15 years (32). But, as with methanol production from wood, the demand for ethanol will be satisfied for the near future by existing synthetic sources, unless it becomes necessary to use it in gasoline blends.
