Abstract:
... Propionate is a crucial intermediate during methane fermentation. Investigating the effects of different kinds of inhibitors on the propionate-degrading microbial community is necessary to develop countermeasures for improving process stability. In the present study, under inhibitory conditions (acetate, propionate, sulfide, and ammonium addition), the dynamic changes of the propionate-degrading m ...

Abstract:
... Considering bioethanol production, extensive research has been performed to decrease inhibitors produced during pretreatments, to diminish energy input, and to decrease costs. In this study, sugarcane bagasse was pretreated with NaOH, H₂SO₄, and water. The higher concentration of phenols, 3.3 g/L, was observed in biomass liquid fraction after alkaline pretreatment. Acid pretreatment was responsibl ...

Abstract:
... Pectin, as one of the most widely used functional polysaccharide, can be abundantly extracted from apple pomace which is the main by-product of apple juice industry. In the case of 110 min, 10% (w/w) acetic acid (AA), and 100 °C, extraction yield of pectin reached 19.6%. Compared with mineral acid-extracted pectin, the yield, molecular weight, galacturonic acid content, and DE of the AA-extracted ...

Abstract:
... Itaconic acid (IA; a building block platform chemical) is currently produced industrially from glucose by fermentation with Aspergillus terreus. In order to expand the use of IA, its production cost must be lowered. Lignocellulosic biomass has the potential to serve as low-cost source of sugars for IA production. It was found that the fungus cannot produce IA from dilute acid pretreated and enzyma ...

Abstract:
... Pre-pulping extraction is a means of deriving a hemicellulose-rich process stream from the front end of a kraft pulp mill. When the extraction is carried out using green liquor, pulp quality and quantity can be retained while still releasing hemicelluloses and acetic acid (HAc) for recovery as bioprocessing feedstock or chemical products. The HAc that is present in the wood extraction is inhibitor ...
