This study evaluated the effects of dilution rate and forage-to-concentrate ratio on gas production by rumen microbes. Continuous cultures were used to monitor methane production at three liquid dilution rates (3.2, 6.3, or 12.5%/h) and three forage-to-concentrate ratios (70:30, 50:50, or 30:70). Filtered ruminal contents were allowed 6 d of adaptation to diets followed by 7 d of data collectio...

Conditioning of lignocellulosic hydrolysates with sulfur oxyanions, such as dithionite, is one the most potent methods to improve fermentability by counteracting effects inhibitory by-products generated during hydrothermal pretreatment under acidic conditions. The pH, treatment temperature, and dithionite dosage were explored in experiments softwood hydrolysates, sodium Saccharomyces cerevisiae...

background: chronic obstructive pulmonary disease (copd) is a major public health problem worldwide. smoking is the number one cause of copd; however, genetic, environmental and dietary factors contribute to the etiology of this disease. in this study, we assessed the association between three diet quality indices -the healthy eating index-2005 (hei-2005), the healthy eating index-2010 (hei-201...

To support the inefficient limitation of long-term biosystem by well-known simultaneous saccharification and fermentation (SSF), electron beam irradiated rice straw (at 80 kGy, 1 MeV, and 0.12 mA) was fermented using fungal-based simultaneous saccharification and fermentation (FBSSF) by saprophytic zygomycetes Mucor indicus. Based on the growth optimization (by response surface methodology), th...

The inhibitors derived from degradation of lignocellulose have adverse impacts on fermentation, which is considered to be a fundamental problem in bioethanol production. Fermentation of steam-exploded corn stover prehydrolyzate by Pichia stipitis showed that phenolic compounds had much higher inhibitory effects than weak acids and furan at high fermentation pH. Two types of organobentonite (cet...
