Assessing the mutagenicity of protic ionic liquids using the mini Ames test
Sustainable Chemical Processes - Tập 3 - Trang 1-11 - 2015
Protic ionic liquids (PILs) have been suggested as “greener” alternatives to conventional solvents in various industrial applications. In order to assess their suitability for such purposes, a thorough evaluation of their toxicity, mutagenicity, carcinogenicity and environmental impact is crucial. Whilst some studies have been published concerning the biodegradability and toxicity towards microorg...... hiện toàn bộ
Use of solar energy for biodiesel production and use of biodiesel waste as a green reaction solvent
Sustainable Chemical Processes - Tập 2 - Trang 1-10 - 2014
Due to the depletion of fossil fuel energy sources, new alternative energy sources are becoming prevalent in our society. Biodiesel has been recognized as an attractive replacement for depleting energy sources since it is produced mainly from vegetable oils and animal fats, is a renewable resource, and is non-toxic. The synthesis of biodiesel involves heating a triglyceride with methanol (or ethan...... hiện toàn bộ
Differential interactions of halophilic and non-halophilic proteases with nanoparticles
Sustainable Chemical Processes - Tập 2 - Trang 1-8 - 2014
Increase in the industrial use of nanomaterials and nanoparticles (NPs) make their release into the environment inevitable. This may lead to environmental contamination and exposure of the biological/ microbial diversity. Nanoparticles have been reported to impregnate the cells and interact with cellular biomolecules especially proteins and DNA, leading to nanotoxicity in many cases. The present w...... hiện toàn bộ
Novel perspectives for evolving enzyme cocktails for lignocellulose hydrolysis in biorefineries
Sustainable Chemical Processes - Tập 1 - Trang 1-12 - 2013
The unstable and uncertain availability of petroleum sources as well as rising cost of fuels have shifted global efforts to utilize renewable resources for the production of greener energy and a replacement which can also meet the high energy demand of the world. Bioenergy routes suggest that atmospheric carbon can be cycled through biofuels in carefully designed systems for sustainability. Signif...... hiện toàn bộ
Nonribosomal peptides synthetases and their applications in industry
Sustainable Chemical Processes - Tập 4 - Trang 1-8 - 2016
Nonribosomal peptides are products that fall into the class of secondary metabolites with a diverse properties as toxins, siderophores, pigments, or antibiotics, among others. Unlike other proteins, its biosynthesis is independent of ribosomal machinery. Nonribosomal peptides are synthesized on large nonribosomal peptide synthetase (NRPS) enzyme complexes. NRPSs are defined as multimodular enzymes...... hiện toàn bộ
Environmental assessment of residues generated after consecutive acid-base pretreatment of sugarcane bagasse by advanced oxidative process
Sustainable Chemical Processes - Tập 1 - Trang 1-10 - 2013
Biofuels produced from sugarcane bagasse (SB) have shown promising results as a suitable alternative of gasoline. Biofuels provide unique, strategic, environmental and socio-economic benefits. However, production of biofuels from SB has negative impact on environment due to the use of harsh chemicals during pretreatment. Consecutive sulfuric acid-sodium hydroxide pretreatment of SB is an effective...... hiện toàn bộ
Recent advances in application of chitosan in fuel cells
Sustainable Chemical Processes - Tập 1 - Trang 1-12 - 2013
Fuel cells are electrochemical devices which convert chemical energy into electrical energy. Fuel cells have attracted attention due to their potential as a promising alternative to traditional power sources. More recently, efficient and environmentally benign biopolymer “chitosan” have been extensively investigated as a novel material for its application in fuel cells. This biopolymer can be used...... hiện toàn bộ
The use of combination of zeolites to pursue integrated refined pyrolysis oil from kraft lignin
Sustainable Chemical Processes - - 2014
A mixture of Y and M type zeolites were applied to pyrolyze kraft softwood (SW) lignin with the objective of studying the combination effect of different types of zeolite on pyrolysis. The chemical structures of the subsequent pyrolysis oils were examined. Nuclear Magnetic Resonance (NMR) spectroscopy including 13C, 31P of phosphitylated bio-oils, Heteronuclear Single-Quantum Correlation (HSQC)-NM...... hiện toàn bộ
Progress towards a more sustainable synthetic pathway to ibuprofen through the use of solar heating
Sustainable Chemical Processes - Tập 4 - Trang 1-9 - 2016
The ACS Green Chemistry Institute Pharmaceutical Roundtable was formed in 2005 to encourage the incorporation of green chemistry techniques into the synthetic pathways of pharmaceuticals. Through this initiative, synthetic pathways of several pharmaceuticals have been altered to adapt more environmentally friendly procedures. The amount of electricity required to complete chemical reactions have b...... hiện toàn bộ
Enzyme promiscuity: using the dark side of enzyme specificity in white biotechnology
Sustainable Chemical Processes - Tập 2 - Trang 1-9 - 2014
Enzyme promiscuity can be classified into substrate promiscuity, condition promiscuity and catalytic promiscuity. Enzyme promiscuity results in far larger ranges of organic compounds which can be obtained by biocatalysis. While early examples mostly involved use of lipases, more recent literature shows that catalytic promiscuity occurs more widely and many other classes of enzymes can be used to o...... hiện toàn bộ
