Sustainable Bioproducts (SB) proposes to develop an encapsulated biofilm-biomat reactor that will efficiently convert mission relevant feedstocks to usable products under zero gravity conditions. The bioreactor will be based on SB’s proprietary fermentation platform for converting a wide variety of waste streams into a multitude of usable products. SB’s bioreactor platform is simple, does not require energy during fermentation (other than temperature control), requires little water, and produces a very dense, easily harvested, consolidated/textured biomats with little to no waste. The biofilm-biomat fermentation technology enables growth on extreme media such as human waste (urine/feces) and produces a highly consolidated and textured biomass without the requirement of a separation or concentration step. Relatively high biomass production rates (0.55 g/L/h dry biomass) and high culture densities (100-180 g/L) are achieved without the need for active aeration or agitation. Scale-up of the system vertically or horizontally is simple and does not result in decreased productivity. The NASA sponsored research will optimize conversion of mission relevant feedstocks (human waste, food waste, plant materials) by adjusting reactor design and growth conditions. The biofilm-biomats produced in the optimized reactor system will be highly textured, 0.2 to 2.5 cm thick with a dry matter content of 10-18% and can be readily used for mission critical needs such as meat alternatives, other appetizing foods, fuels and building materials.
