Fermentation of Corn By-Products: From Agrifood Waste to Higher Value Antioxidant Products

Feed ingredient Co-Products of ethanol Fermentation from Corn

Introduction Processing conditions prior to or after fermentation of corn to ethanol can greatly influence the quantity, quality, and nutritional composition of co-products. Most of the increase in ethanol production in the U.S. is expected to come from dry grind corn plants. Because of the large expected increase in distillers’ dry grains with solubles (DDGS) production, processing modificatio...

Effects of extracts derived from pistachio by-products on ruminal fermentation and methane production

The objective of this study was to evaluate the effects of different doses of pistachio by-product (PBP) extracts supplemented with alfalfa hay (AH) or barley grain (BG) on microbial fermentation in an in vitro fermentation system. The total extracted phenolic compounds were 36.96, 65.78, 67.02 and 8.85% and total extracted tannin contents were 37.11, 59.64, 56.87 and 7.55% when PBP was extract...

Fermentation Products of Cellulose

IN WORKING on the products resulting from the anaerobic decomposition of biologic waste material, the writers, with others (1), have observed that the reactions, which are brought about by bacteria, cause the formation of considerable amounts of gas. This gas is principally methane and carbon dioxide, with small amounts (3-5 per cent) of hydrogen and nitrogen, the latter probably from solution ...

Inoculant effects on alfalfa silage: fermentation products and nutritive value.

The effect of 14 microbial inoculants on the fermentation and nutritive value of alfalfa silages was studied under laboratory conditions. The first cut (477 g of dry matter/kg) and second cut (393 g of dry matter/kg) of a second-year alfalfa stand were ensiled in 2 trials. In both trials alfalfa was harvested with standard field equipment. All inoculants were applied at 1.0 x 10(6) cfu/g of cro...
