امروزه استفاده از منابع انرژی پراکنده کاربرد وسیعی یافته است . اگر چه این منابع بسیاری از مشکلات شبکه را حل می کنند اما زیاد شدن آنها مسائل فراوانی برای سیستم قدرت به همراه دارد . استفاده از میکروشبکه راه حلی است که علاوه بر استفاده از مزایای منابع انرژی پراکنده برخی از مشکلات ایجاد شده توسط آنها را نیز منتفی می کند . همچنین میکروشبکه ها کیفیت برق و قابلیت اطمینان تامین انرژی مشترکان را افزایش ...
15 صفحه اولA simple quick route to fullerene amino acid derivatives.
Two new fullerene amino acids have been prepared by dipolar addition to C(60) of either the Boc- or Fmoc-Nalpha-protected azido amino acids derived from phenylalanine and lysine. UV-visible and CV studies indicate the as prepared amino acids are a mixture of 5,6-open (major product) and 6,6-closed (minor product) derivatives that may be readily separated.
متن کاملContinuous Production of 6-amino Penicillanic Acid (6-APA) by Agarose Immobilized Penicillin Acylase in a Packed Column Reactor
Penicillin acylase, an industrially important biocatalyst catalyzes the conversion of penicillins to 6-amino penicillanic acid (6-APA) which is the main precursor for the production of semi-synthetic -lactam antibiotics. The present work involves the continuous production of 6-APA in a packed column reactor by using agarose immobilized penicillin acylase as a block polymer. The strain Escherich...

Penicillin acylase, an industrially important biocatalyst catalyzes the conversion of penicillins to 6-amino penicillanic acid (6-APA) which is the main precursor for the production of semisynthetic ß-lactam antibiotics. The present work involves the continuous production of 6APA in a packed column reactor by using agarose immobilized penicillin acylase as a block polymer. The strain Escherichi...
متن کاملIn vitro studies of a new semisynthetic penicillin, 6-(d-alpha-sulfoaminophenylacetamido)-penicillanic acid.
The activity of 6-(D-alpha-sulfoaminophenylacetamido)-penicillanic acid was determined against 357 clinical isolates of gram-negative bacilli by use of the tube-dilution technique. The majority of the isolates of Pseudomonas species were inhibited by 200 mug/ml or less of this antibiotic. Most of the isolates of Escherichia coli had a minimal inhibitory concentration of 50 mug/ml or less. Seven...
