- Abstract:
- ... The plastic disposal problem has been augmented over the years due to the surge in utilization of single-use plastics, the indiscriminate discarding of plastics, and space limitations associated with landfill sites. Therefore, in this study the biodegradable, biorenewable, and biocompatible plastic substitutes, poly(hydroxyalkanoate) (PHA) biopolymers were synthesized from low-value and high-volum ...

- Abstract:
- ... Butanol can be produced biologically through fermentation of lignocellulosic biomass-derived sugars by Gram-positive Clostridium species. For cost-effective production, increased butanol fermentation titers are desired. However, the currently available butanol-fermenting microbes do not tolerate sufficiently high butanol concentrations; thus, new butanol-tolerant strains are desired. One promising ...

- Abstract:
- ... Itaconic acid (IA), is a versatile platform chemical that is produced by Aspergillus terreus using glucose as carbon source. Lignocellulosic biomass can be used as a low cost source of sugars for IA production. However, A. terreus does not produce IA even after 100 fold dilution from enzymatically hydrolyzed wheat straw pretreated with dilute acid. In addition to organic inhibitors, Mn²⁺ strongly ...

- Abstract:
- ... Biobutanol is one of the most promising renewable biofuels, which can be produced from lignocellulosic biomass by Clostridium. However, due to the dense structure of lignin, biomass is difficult to be hydrolyzed into fermentable sugars. This study has developed a short time (90 min) and low energy consumption (120 °C) pretreatment process using deep eutectic solvent (DES). Importantly, the cellulo ...

- Abstract:
- ... BACKGROUND: Butanol, a superior biofuel to ethanol, can be produced by fermentation of renewable feedstocks such as corn or molasses. Since costs of these feedstocks are high, this biofuel should be produced from economic substrates. Recent studies have identified yellow top (YT) (Physaria fendleri) as an economical feedstock which is currently used for landfill, thus causing environmental polluti ...

- Abstract:
- ... The decreasing supply of fossil fuels and increasing environmental concern of food waste disposal have raised interests in food waste conversation to biofuels such as butanol. Apple pomace, a food processing waste rich in carbohydrates, is a good feedstock for butanol production. The goal of this study is to present and evaluate a process to thoroughly convert apple pomace water soluble sugars (WS ...

- Abstract:
- ... Lactobacillus buchneri and Oenococcus oeni are two unique ethanol-tolerant Gram-positive bacteria species. Genome comparison analyses revealed that L. buchneri and O. oeni possess a pntAB locus that was absent in almost all other lactic acid bacteria (LAB) genomes. Our hypothesis is that the pntAB locus contributes to the ethanol tolerance trait of these two distinct ethanol-tolerant organisms. Th ...

In this study, PMS was treated by de-ashing, fiber regeneration and enzymatic hydrolysis. The PMS hydrolysate was used for butyric acid production by Clostridium tyrobutyricum B-67062/RPT 4213. We reported that 8.52 and 8 ...

- 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:
- ... Sweet sorghum syrups represent a renewable raw material that can be available year-round for production of biofuels and biochemicals. Sweet sorghum sugars have been used as sources for butanol production in the past but most often the studies focused on sweet sorghum juice and not on sweet sorghum syrups. Therefore, we investigated the feasibility of using the syrups as feedstock. Initial studies ...
