High performance green barriers based on nanocelluloseAbstract
With the increasing environmental concerns such as sustainability and end-of-life disposal challenges, materials derived from renewable resources such as nanocellulose have been strongly advocated as potential replacements for packaging materials. Nanocellulose can be extracted from various plant resources through mechanical and chemical ways. Na... ...

Heat integration of combined 1st and 2nd generation ethanol production from wheat kernels and wheat straw
Tập 2 - Trang 1-20 - 2014
Reducing the energy used in an ethanol plant is an important step towards reducing both the cost and environmental impact of the process. Pinch technology was used to analyze the energy utilization and to investigate possible energy savings in stand-alone and combined 1st and 2nd generation ethanol production plant designs. Different heat sources and sinks in the plant were identified to improve e......
Microwave-assisted catalytic esterification of α-glucoisosaccharino-1,4-lactone with tall oil fatty acids
Tập 4 - Trang 1-5 - 2016
Carbohydrates-rich materials are partly degraded during alkaline kraft pulping into a complex mixture of aliphatic carboxylic acids consisting of α-glucoisosaccharinic acid as one of the main acids. On the other hand, crude tall oil, containing significant amounts fatty acids, is obtained as a by-product from kraft pulping. One interesting novel approach is to utilize chemically both these side-st......
Use of solar energy for biodiesel production and use of biodiesel waste as a green reaction solvent
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......
Improved one-pot synthesis of N, N-diisopropyl-3-(2-Hydroxy-5-methylphenyl)-3-phenyl propanamide; a key intermediate for the preparation of racemic Tolterodine
Tập 2 - Trang 1-6 - 2014
An improved, cost effective process for the synthesis of N,N-diisopropyl-3-(2-hydroxy-5-methylphenyl)-3-phenylpropanamide; a key intermediate for the preparation of Tolterodine and its related substances were described. The process features one pot synthesis employing inexpensive reagents.
Scale up and efficient bioethanol production involving recombinant cellulase (Glycoside hydrolase family 5) from Clostridium thermocellum
Tập 1 - Trang 1-11 - 2013
Lignocellulose degrading fungal enzymes have been in use at industrial level for more than three decades. However, the main drawback is the high cost of the commercially available Trichoderma reesei cellulolytic enzymes. The hydrolytic performance of a novel Clostridium thermocellum cellulolytic recombinant cellulase expressed in Escherichia coli cells was compared with the naturally isolated cell......
Recent advances in enzyme promiscuity
Tập 4 - Trang 1-7 - 2016
Enzyme promiscuity is defined as the capability of an enzyme to catalyze a reaction other than the reaction for which it has been specialized. Although, enzyme is known for its specificity, many enzymes are reported to be promiscuous in nature. However, the promiscuous function may not be relevant in physiological conditions. The reasons could be either very low level of catalytic activity or unav......
Isolation, purification and characterization of Trichothecinol-A produced by endophytic fungus Trichotheciumsp. and its antifungal, anticancer and antimetastatic activities
Tập 2 - Trang 1-9 - 2014
A total of 30 endophytic fungi (AAP-PS 1–30) were isolated from the medicinal herb Phyllanthus amarus and screened for the production of Trichothecinol-A. Out of all the endophytic strains screened for Trichothecinol-A production, the culture filtrate of AAP-PS-1 extracted with ethyl acetate yielded Trichothecinol-A extracellularly in appreciable amounts. Trichothecinol-A was purified, quantified ......
