Summary
To date fermentations of marine algal species run at a controlled pH of 5.5 to 6.0 have exhibited essentially complete conversion to organic acids in as little as 16 days. (By complete conversion is meant conversion of each hexose unit to three acetic acid molecules or higher organic acids on a reducing equivalent basis.) As a result of these rapid rates and high conversions economic calculations have shown that processing costs are sufficiently low to encourage commercial development of this process. In the course of this work a diffusion membrane extraction system has been developed for removing organic acids from the fermentation broth. In addition, a fixed packed bed fermenter with a capacity of approximately 300 liters has been constructed and operated for a six month period. Another significant result is that fermentation at thermophilic temperatures (55/sup 0/C) gives higher ratios of acetic acid to total acid product than at mesophilic temperatures (37/sup 0/C). Manuscripts of two technical presentations based on this work are attached.
