Kirk-Othmer Encyclopedia of Chemical Technology数据库介绍及实例

VERY few veterinary surgeons have thought fit to write a book on diseases of poultry. Mr. Ernest Gray has done justice to the subject and is to be congratulated on his effort. A book of this size, written by one with specialized knowledge, will add to the value of any library or private bookshelf. Diseases of Poultry Their Aetiology, Diagnosis, Treatment and Control; with a Section on the Normal Anatomy and Physiology of the Fowl. By Ernest Gray. (Lockwood's Agricultural and Horticultural Handbooks.) Pp. x + 198 + 16 plates. (London: Crosby Lockwood and Son, Ltd., 1940.) 9s. 6d. net.

Nanoscale hydroxyapatite particles for bone tissue engineering

Microalgae have recently attracted considerable interest worldwide, due to their extensive application potential in the renewable energy, biopharmaceutical, and nutraceutical industries. Microalgae are renewable, sustainable, and economical sources of biofuels, bioactive medicinal products, and food ingredients. Several microalgae species have been investigated for their potential as value-added products with remarkable pharmacological and biological qualities. As biofuels, they are a perfect substitute to liquid fossil fuels with respect to cost, renewability, and environmental concerns. Microalgae have a significant ability to convert atmospheric CO2 to useful products such as carbohydrates, lipids, and other bioactive metabolites. Although microalgae are feasible sources for bioenergy and biopharmaceuticals in general, some limitations and challenges remain, which must be overcome to upgrade the technology from pilot-phase to industrial level. The most challenging and crucial issues are enhancing microalgae growth rate and product synthesis, dewatering algae culture for biomass production, pretreating biomass, and optimizing the fermentation process in case of algal bioethanol production. The present review describes the advantages of microalgae for the production of biofuels and various bioactive compounds and discusses culturing parameters.

The promising future of microalgae: current status, challenges, and optimization of a sustainable and renewable industry for biofuels, feed, and other products

The inherent structure tunability, good affinity with CO2, and nonvolatility of ionic liquids (ILs) drive their exploration and exploitation in CO2 separation field, and has attracted remarkable interest from both industries and academia. The aim of this Review is to give a detailed overview on the recent advances on IL-based materials, including pure ILs, IL-based solvents, and IL-based membranes for CO2 capture and separation from the viewpoint of molecule to engineering. The effects of anions, cations and functional groups on CO2 solubility and selectivity of ILs, as well as the studies on degradability of ILs are reviewed, and the recent developments on functionalized ILs, IL-based solvents, and IL-based membranes are also discussed. CO2 separation mechanism with IL-based solvents and IL-based membranes are explained by combining molecular simulation and experimental characterization. Taking into consideration of the applications and industrialization, the recent achievements and developments on the t...

Porous hydroxyapatite for artificial bone applications

A review of chemical absorption of carbon dioxide for biogas upgrading

Bromelain is a mixture of proteolytic enzymes derived from the stems and juice of pineapples. It has been
extensively used in food industry; for meat tenderization, baking processes, and in prevention of browning
of apple juice. Stem bromelain is a highly accepted phytotherapeutic agent. It has anti-tumor and antiinflammatory
effects, use in wound healing, as digestive aids, etc. This review aims at presenting a detailed
account on the level of achievement on bromelain production from the conventional methods. Specifically,
the isolation, purification and the biochemical properties of bromelain are discussed. The study also
focused on the current trends and the progress made in the production of recombinant stem bromelain in
Escherichia coli. This involved cloning of stem bromelain gene and its expression, optimization of labscale
fermentation conditions for E. coli harboring recombinant bromelain as well as the enzyme thermal
and storage stability measured using differential scanning calorimetry. It is hoped that this review would
provide relevant information to contemporary researchers who are active in the field of bromelain and other
related proteases.

Bromelain Production: Current Trends and Perspective

There is a growing interest in bioethanol as biofuel since it has the possibility to be the potential substitute for fossil fuels. Ethanol batch fermentation of Saccharomyces cerevisiae strain was carried out in 10 L stirred tank bioreactor for 72 h at 0.075 vvm of aeration and 75 rpm of agitation speed. 85.8% conversion efficiency of ethanol production from glucose substrate was accomplished. This study investigated the S. cerevisiae growth kinetics and ethanol productivity using computer simulation of four different kinetic models which are: Monod, Contois, Modified Monod and Teisser. Teisser model gave marginally better fit than other models tested as it obtained the highest correlation coefficient (0.96299). Based on Leudking-Piret model, it could be concluded that ethanol batch fermentation is a non-growth associated process.

Study of growth kinetic and modeling of ethanol production by Saccharomyces cerevisae

Bromelain, a cysteine protease with various therapeutic and industrial applications, was expressed in Escherichia coli, BL21-AI clone, under different cultivation conditions (post-induction temperature, L-arabinose concentration and post-induction period). The optimized conditions by response surface methodology using face centered central composite design were 0.2% (w/v) L-arabinose, 8 hr and 25°C. The analysis of variance coupled with larger value of R2 (0.989) showed that the quadratic model used for the prediction was highly significant (p < 0.05). Under the optimized conditions, the model produced bromelain activity of 9.2 U/mg while validation experiments gave bromelain activity of 9.6 ± 0.02 U/mg at 0.15% (w/v) L-arabinose, 8 hr and 27°C. This study had innovatively developed cultivation conditions for better production of recombinant bromelain in shake flask culture.
