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 ...

The increase in the costs of storage and disposal post-production residues has resulted search for new directions their recycling, which is closely related to necessity protecting natural environment promoting a circular economy. Moreover, apparent interest shown by food market raw materials with high antioxidant activity implies an increasing use by-products. objective study was determine effe...

Wastewater from bioethanol plants is classified as highly concentrated in terms of organic pollution precisely due to distillery stillage. The main problem the disposal stillage processing liquid phase, volume which up 92% all wastewater a plant. existing treatment technologies plant can be conditionally divided into four types: evaporation, aerobic biological with fodder yeast production, anae...

Yearling and calf finishing trials (replicated over 2 yr) evaluated the feeding value of wet distillers byproducts (wet distillers grains and thin stillage). An additional trial estimated the amount of thin stillage bypassing the rumen when consumed by drinking. Yearlings were 5, 10, and 20% more efficient (linear, P < .01; quadratic, P = .05), whereas calves were 2, 6, and 14% more efficient (...

A continuous hydrothermal process is demonstrated, for the first time, that can operate at low gasification temperature (430 °C) and residence time (20 s) by combining supercritical water (SCWG) partial oxidation with in situ synthesis of virgin metal oxide nano-catalyst. Using olive wastewater as feedstock, this study experimentally investigated impact multiple variables: (1) COD feed concentr...
