engineering of microorganisms for their improvement as steroid transforming agents are the areas of drug development. Site selection oxygenation‚ particularly hydroxylation of exogenous steroids is frequent in bacteria genera Bacillus. Several microbial bioconversion of steroids and sterols have been reported‚ focusing mainly on steroid hydroxylations‚ ∆1-dehydrogenation and sterol side-chain cleavage. These biotransformations‚ mostly associated to chemical synthesis steps‚ have provided adequate

| Fossil Fuel: Natural Gas | Renewable resource: Wind Power | Describe this resource | Natural Gas in a Hydrocarbon gas that is naturally occurring. It consists of mostly methane and is used as fuel for some vehicles and heating the home. | Wind power is one of the cleanest sources of electricity. It usually involves a fan that spins‚ and the energy is transported to a generator. | Advantages of this resource (include at least two) | 1. Very abundant underground.2. Is cleaner than most other

Microbial Keratitis Microbial keratitis‚ or corneal infection‚ is a very rare but serious complication of contact lens wear. This website provides information on the infection and its symptoms‚ how to minimise your risk‚ and what to do if you suspect you have an infection. The website provides information resulting from the Australian and New Zealand Microbial Keratitis Study‚ which concluded in 2005. This was a major study looking at the rate and risks of microbial keratitis‚ which collected

pH and Microbial Growth Introduction: Each organism has an optimum environment for growth‚ which includes pH level. Organisms that grow at near neutral pH levels are called neutrophiles. Those that grow best in acidic pH values are called acidophiles. Others‚ yet‚ grow best in alkaline pH values and are called alkaliphiles. In this lab‚ each group was assigned an organism‚ which was then used to inoculate 6 different pH levels. Materials and Methods: Followed lab procedure 29‚ “pH and

John Vincent Armada EXPERIMENT NO. 5 MICROBIAL EXAMINATION OF CANNED FOODS I. Introduction Canned foods are the most prominently used packed food all over the world. We can see the canned food in each house hold. People use them because they are easy to be maintained & need less time to be cooked. Moreover they don ’t loose their natural taste as well. But to keep their taste & quality for long time certain care should be taken while using them. Moreover there are certain
