A lignocellulose to bisabolene bioconversion process is demonstrated be fully compatible with [Ch][Lys].
This scale-up study demonstrated the feasibility of an ionic liquid (IL) pretreatment process at 40 kg scale, using IL 1-ethyl-3-methylimidazolium acetate ([C2C1Im][OAc]) as solvent. The was followed by enzymatic hydrolysis through which efficiency for biomass conversion to monomeric sugars determined. results show that 43 wt% switchgrass dissolved in after 2 h 160 °C with 15 solid loading. A 120 pretreated 96% glucan and 98% xylan conversion. [C2C1Im][OAc] has been successfully scaled up...
Lignocellulosic biorefineries have tonnage and throughput requirements that must be met year round there is no single feedstock available in any given region capable of meeting the price availability demands scheduled for deployment. Significant attention has been historically to agriculturally derived feedstocks; however, a diverse range wastes, including municipal solid wastes (MSW), also potential serve as feedstocks production advanced biofuels not extensively studied. In addition, ionic...
Lignocellulosic biomass is an important resource for renewable production of biofuels and bioproducts. Enzymes that deconstruct this are critical the viability biomass-based biofuel processes. Current commercial enzyme mixtures have limited thermotolerance. Thermophilic fungi may provide with greater thermal stability leading to more robust Understanding induction biomass-deconstructing enzymes in thermophilic will foundation strategies construct hyper-production strains. Induction...
Wet anaerobic storage of corn stover can provide a year-round supply feedstock to biorefineries meanwhile serving an active management approach reduce the risks associated with fire loss and microbial degradation. logistics systems employ particle size reduction early in chain through field-chopping which removes dependency on drying prior baling, expands harvest window, diminishes biorefinery requirements. Over two years, in-field forage chopping was capable reducing over 60% 6 mm or less....
Bisabolene bioconversion is demonstrated using pilot-scale hydrothermal pretreated biomass four feedstocks with in-depth characterization analysis.
Process development and scale-up of an ionic liquid based process that converts actual household waste (cellulose rich fraction) to fermentable sugars.
The conversion of municipal solid waste (MSW) and lignocellulosic biomass blends to methyl ketones (MKs) was investigated by using bioderived ionic liquid (bionic liquid)-based hydrolysates followed fermentation with an engineered Escherichia coli strain. were produced a one-pot process six types MSW-biomass blends, choline-based bionic liquids, commercial enzymes. Based on the sugar yields, one blend (corn stover/MSW=95:5, w/w) two liquids {cholinium lysinate ([Ch][Lys]) cholinium aspartate...
This work aimed to develop an efficient L-leucine industrial production strain of Corynebacterium glutamicum by using metabolic engineering. A recombinant C. was constructed expressing a feedback-resistant leuA-encoded 2-isopropylmalate synthase (IPMS) that carries three amino acid exchanges (R529H, G532D and L535V) from the mutant ML1-9 which obtained screening for structural analogues. In order improve expression IPMS, strong promoter (tac promoter) used ensure rate-limiting enzyme....
Postconsumer absorbent hygiene products (AHPs), one of the most intractable municipal solid waste (MSW) streams, are generally subjected to landfills, causing urban management difficulties and environmental pollution. This study investigated viability recycling cellulose component from postconsumer AHPs, demonstrated fermentability obtained cellulosic sugars for bioethanol production, evaluated technical feasibility process through scale-up. A set integrated unit operations was developed...
This article provides a method to convert landfill-designated municipal solid waste (MSW, paper-rich and food-rich) bioproducts through integrated bioprocessing, also way of improving the MSW diversion rate reduce environmental stress. Compositional analysis, bacterial community profiling, homogenization, enzymatic hydrolysis, yeast fermentation were performed on collected samples. Results show that these two types streams are potential feedstock sources for biorefineries based their...

Solving symmetric positive semidefinite linear systems is an essential task in many scientific computing problems. While Jacobi-type methods, including the classical Jacobi method and weighted method, exhibit simplicity their forms friendliness to parallelization, they are not attractive either because of potential convergence failure or slow rate. This paper aims showcase possibility improving methods by employing Nesterov's acceleration technique that results accelerated with improved...
