The formation of lignin-like structures by the degradation primarily plant polysaccharides has been observed after severe thermochemical acidic pretreatment lignocellulosic biomass.
Combinatorial pretreatments with a low holding temperature were developed in an effort to synergistically improve the carbohydrate output and lignin processability from corn stover.
Deconstruction with low-cost ionic liquids (ionoSolv) is a promising method to pre-condition lignocellulosic biomass for the production of renewable fuels, materials and chemicals.
Sequential organosolv fragmentation approach (SOFA) enhances the self-assembling process of high-quality lignin nanoparticles (LNPs) by tailoring chemistry in biorefineries.
Cooperative valorization of lignin and residual sugar has the potential to improve sustainability profitability biorefineries.
To make biorefineries sustainable, codesign of fractionation technologies and lignin valorization has been found to be essential. Combinatorial organosolv pretreatment (COP) was thus developed in an effort efficiently produce sugars improve processability for the fabrication nanoparticles (LNPs). COP produced greater than a 90% glucose yield 73% xylose yield, suggesting improved sugar release from biomass. LNPs were fabricated fractionated by via antisolvent precipitation. The smallest...
Alkyl benzoate esters have gained importance due to their application in a variety of industries such as flavor, cosmetics, and pharmaceuticals. Effect microwave irradiation the enzymatic transesterification methyl with different alcohols, viz., n-butanol, n-pentanol, n-hexanol, n-octanol, benzyl alcohol, isoamyl 2-ethyl-1-hexanol, was investigated. Synthesis n-hexyl chosen model reaction. Different enzymes Novozym 435, Lipozyme TL IM, RM Lipase AYS Amano were screened under irradiation. 435...
Corynebacterium glutamicum has been successfully employed for the industrial production of amino acids and other bioproducts, partially due to its native ability utilize a wide range carbon substrates. We demonstrated C. as an efficient microbial host utilizing diverse substrates present in biomass hydrolysates, such glucose, arabinose, xylose, addition natural assimilate lignin-derived aromatics. As case study demonstrate bioproduction capabilities, L-lactate was chosen primary fermentation...
High-protein algae bioproduct system boundaries for environmental sustainability risk analysis.
Microbial production of esters has recently garnered wide attention, but the current metrics are low. Evidently, ester precursors (organic acids and alcohols) can be accumulated at higher titers by microbes like Escherichia coli. Hence, we hypothesized that their 'direct esterification' using esterases will efficient. We engineered from various microorganisms into E. coli, along with overexpression ethanol lactate pathway genes. High cell density fermentation exhibited strains possessing...
In the last 20 years, biodiesel consumption in United States has rapidly increased to ∼2 billion gallons per year as a renewable supplement fossil fuel. However, further expansion of use is currently limited part by poor cold weather performance, which prevents year-round blending and necessitates blend walls ≤5% v/v. order provide diesel fuel blendstock with improved performance (cloud point, pour filter plug point), while at same time maintaining other required specifications, several...
Proper timing of switchgrass harvest for bioenergy is important to maximize yield and optimize end use conversion. Proposed windows range from peak biomass the following spring after overwintering in field. There are various pros cons associated with timing: earlier harvests but can remove nutrients field that may require replacement, while later have reduced yields due weathering nutrient resorption belowground tissues. Switchgrass composition changes during period, losses potential...
Abstract Response surface methodology (RSM) was used to model and optimize the immobilized Candida antarctica lipase B catalysed synthesis of butyl-4-methyl-3-oxopentanoate. To determine optimum conditions transesterification, a four-factor five-level central composite rotatable design (CCRD) used. The factors studied were enzyme load (A), reaction temperature (B), methyl-4-methyl-3-oxopentanoate concentration (C) n-butanol (D). A quadratic polynomial regression analyze experimental data at...
Microwave irradiation and biocatalysis are important rapidly developing technologies in green sustainable engineering. The synergistic effect of microwave lipase catalysis transesterification ethyl (2E)-3-phenylprop-2-enoate 4,8-dimethylnon-7-en-1-ol was studied using immobilized enzymes such as Novozym 435, Lipase AYS amino, Lipozyme RMIM TL IM. 435 the best catalyst amongst studied. effects various parameters affecting conversion initial rates were to establish kinetics mechanism. There is...
The sustainability and economic feasibility of modern biorefinery depend on the efficient processing both carbohydrate lignin fractions for value-added products. By mimicking biomass degradation process in white-rote fungi, a tailored two-step fractionation was developed to maximize sugar release from switchgrass optimize processability bioconversion. Biomimicking using Formic Acid: Fenton: Organosolv (F 2 O) achieved high lignin. Specifically, pretreated by F O had 99.6% theoretical yield...
