    Abstract: By a method for producing cadaverine by culturing a microorganism that extracellularly secretes lysine decarboxylase, by-production of lysine is suppressed, the yield of cadaverine relative to glucose consumption is improved compared to conventional production methods, and further, the load on the purification step in purification of cadaverine as a raw material for polyamide can be reduced.

    Abstract: A method of producing lactic acid by continuous fermentation characterized by comprising filtering a liquid culture medium of a hyperpolyploid yeast having an ability to produce lactic acid through a porous membrane having an average pore diameter of 0.01 µm or more but less than 1 µm, harvesting the product from the filtrate while maintaining the unfiltered liquid in the liquid culture medium or refluxing thereto, and further adding the fermentation material to the liquid culture medium as described above. According to this method, the production yield of lactic acid by the fermentation can be remarkably elevated in a stable state over a long period of time at a low cost.

    Abstract: This method for producing alcohol from cellulose-containing biomass includes the following steps (1) to (8). Step (1): a step for pre-processing cellulose-containing biomass. Step (2): a step for saccharification, by means of a diastatic enzyme, of the cellulose-containing biomass after the pre-processing as obtained by step (1). Step (3): a step for eliminating saccharification residual solids from the saccharification processing product obtained from step (2). Step (4): a step for culturing an alcohol fermentation microorganism with the aqueous saccharide solution obtained in step (3) as the starting material for fermentation. Step (5): a step for eliminating the alcohol fermentation microorganism from the culture liquid containing the alcohol fermentation microorganism obtained in step (4). Step (6): a step for recovering alcohol by distillation of the alcohol fermentation liquid obtained in step (5). Step (7): a step for filtering the distillation residue liquid obtained in step (6) through a reverse osmosis membrane. Step (8): a step for wastewater treatment of the retentate obtained in step (7).
