Zymomonas mobilis is undoubtedly one of the most unique bacterium within the microbial world. Known since 1912 under the names Termobacterium mobilis, Pseudomonas linderi, and Zymomonas mobilis, reviews on its uniqueness have been published in 1977 and 1988. The bacterium Zymomonas mobilis not only exhibits an extraordinarily uniqueness in its biochemistry, but also in its growth behavior, energy production, and response to culture conditions, as well as cultivation techniques used. This uniqueness caused great interest in the scientific, biotechnological, and industrial worlds. Its ability to couple and uncouple energy production in favor of product formation, to respond to physical and chemical environment manipulation, as well as its restricted product formation, makes it an ideal microorganism for microbial process development. This review explores the advances made since 1987, together with new developments in the pure scientific and applied commercial areas. 相似文献

A process is developed for the autoclave leaching of nickel and manganese with sulfuric acid from the products of catalytic synthesis of industrial diamonds containing 20% Ni and 30% Mn. The optimum conditions for the autoclave processes are determined to be as follows: the temperature range is 150–160°C, the solution acidity is 5 N H2SO4 (230–240 g/l), the leaching duration is 2 h, and the number of processing steps is two. The extraction of the metals into a solution under these conditions is >99% for a total Ni + Co content of <0.4–0.5% in the autoclave leaching cake. The studies performed are related to the search for alternative ways of the catalytic preparation of industrial diamonds that can replace the nonferrous metal leaching technology using aqua regia solutions, which is mainly applied for these purposes under industrial conditions. 相似文献

AbstractMicrowave carbothermal nitridation was used to prepare vanadium nitride from vanadium pentoxide and carbon black, under flowing nitrogen gas at atmospheric pressure. The effect of synthesis temperature, soaking time and the initial concentration of carbon on the final nitrogen content was studied. The nitrogen content in the products reached 12 to 16 wt-%, well within the current requirements of the steelmaking industry. 相似文献

A single-pot enzymatic synthesis of Z-CCK5 (4-8) is presented in this work, employing Z-Gly-Trp-OBzl as acyl donor, under kinetic control. The first goal of the work is the development of a synthetic strategy allowing the use of the same medium for two reactions catalyzed by immobilized alpha-chymotrypsin, discriminating between simultaneous and consecutive addition systems. The second goal is the maximization of the pentapeptide yield as a function of the molar excess of both nucleophiles employed. A maximum yield of 36% was obtained, and the addition strategy as well as the optimal initial concentrations of substrates have been determined. 相似文献
