Production of Ethanol and Biomass from Thin Stillage Using Food-Grade Zygomycetes and Ascomycetes Filamentous Fungi
A starch-based ethanol facility producing 200,000 m 3 ethanol/year also produces ca. 2 million m 3 thin stillage, which can be used to improve the entire process. In this work, five food-grade filamentous fungi, including a Zygomycete and four Ascomycetes were successfully grown in thin stillage containing 9% solids. Cultivation with Neurospora intermedia led to the production of ca. 16 g·L −1 ...
متن کاملFungal oil with EPA in Mucor circinelloides cultivated on thin stillage from corn-to-ethanol production
This study demonstrates the potential of the oleaginous fungus Mucor circinelloides for synthesizing oil rich in polyunsaturated fatty acids when cultivated in thin stillage (TS) and centrifuged thin stillage (CTS) from corn-to-ethanol production. Biomass yield, oil yield and its EPA content were studied at different cultivation periods and carbon to nitrogen ratios. The fungal biomass yield (g...
متن کاملEthanol Production from Maize
The production of fuel ethanol from corn grain is widely carried out in the US, with total current production at 7 billion gallons. This may soon reach 10 billion gallons or more. This chapter addresses the potential of fuel ethanol as an additional source of product based on utilization of the cellulosic (non-food) portions of maize, and in particular the pericarp, cobs, stalks and leaves of t...
متن کاملAnaerobic digestion of whole stillage from dry-grind corn ethanol plant under mesophilic and thermophilic conditions.
Anaerobic digestion of whole stillage from a dry-grind corn-based ethanol plant was evaluated by batch and continuous-flow digesters under thermophilic and mesophilic conditions. At whole corn stillage concentrations of 6348 to 50,786 mg total chemical oxygen demand (TCOD)/L, at standard temperature (0 °C) and pressure (1 atm), preliminary biochemical methane potential assays produced 88±8 L (4...
متن کاملOptimizing of SCP Production from Sugar Beet Stillage Using Isolated Yeast
In this study fungi isolated from the effluent of ethanol factories were identified. Optimal conditions for single cell protein (SCP) production and COD reduction of sugar beet stillage are specified for a species of Hansenula in a continuous culture. Under these conditions 5.7 g dm-3 biomass was produced and 31% of COD was reduced without addition of further nutrients to the beet molasses ...
