Transformation of organic compounds by microbial enzymes

MICROBIAL TRANSFORMATION OF CHOLESTEROL BY MYCOBACTERIUM SMEGMATIS

Mycobacterium smegmatis PTCC 1307 (CIP 73.26) was used as a microbial agent to produce androsta-1,4-diene-3,17-dione (ADD) and androst-4-ene-3,17-dione, two useful precursors in the synthesis of steroid drugs. The side chain of cholesterol, as the substrate, was selectively cleaved in the presence of five enzyme inhibitors. An intermediate structure with intact side chain, cholest-4-ene-3-one, ...

Optimization of organic compounds removal from Wastewater by Electrocoagulation

Introduction: As the most hazardous sewage, hospital wastewater contains various contaminants, and its uncontrolled discharge can seriously damage the environment. Bandar Abbas is located in an arid and semi-arid region therefore, hospital wastewater should be treated through an appropriate and economic method. This study aimed to determine the efficiency of electrocoagulation with aluminum and...

synthesis of 3-aryl-2h-benzo[b]-1,4-oxazines in [omim]bf4 and reduction of organic compounds in methylimidazolium formate

در این پروژه ترکیبات 3-آریل-2h-بنزو[b]-4،1-اکسازین ها از مواد اولیه تجاری مشتقات دو آمینو فنول و ?-هالو کتون های آروماتیک در مایع یونی 1-اکتیل-3-متیل ایمیدازولیوم تترا فلورو بورات([omim]bf4) سنتز شده است. این واکنش توسط باز پتاسیم کربنات محلول از طریق o-آلکیلاسیون و سپس یک واکنش آمیداسیون درون مولکولی خود بخود در مدت زمان کوتاه انجام می شود. ترکیبات 4،1-بنزوکسازین به این روش با بهره خوب تا آلی ...
