The two are often used to refer to same thing. However, fermentor is the proper term for an apparatus, i.e. a bioreactor, while fermenter is the proper term for an organism that uses fermentation as a metabolic process, i.e. the thing that goes in the fermentor.
In general terms, a fermentor is something that, as its name would suggest, ferments; this is, however, not a simple process. The process of fermentation has been known of for thousands of years, but has been mainly used over this time to the glucose found in various fruits, seeds and tubers into alcohol, later used for human consumption. In recent times, however, with increased knowledge of bacteria and fungi, fermentors have been put to a more (some would say) productive. A fermentor, then, is simply put an optimal environment for bacteria and / or fungi to grow in, and the cultivation of said organisms will yield a desirable substancee use.
A bioreactor is a vessel in which is carried out a chemical process which involves organisms or biochemically active substances derived from such organisms. Bioreactors are commonly cylindrical, ranging in size from some liter to cube meters,and are often made of stainless steel. in brief bioreactor can be considered as a large scale operation whose volume/capacity ranges to several litres whereas fermenter only ranges ~2 litres
It is extremely important to differentiate glucose non fermenters from enterobacteriaceae. Enterobacteriaceae is a gram negative bacterium that can cause extreme illness if cross contaminated with a glucose non fermenter.
so that the mixture in the fermenter is aerated and so that the air does not encourage the division of microorganisms such as bacteria.
In Osmosis, water moves from the region of high water concentration through a semi permeable membrane to a region of low water concentration. Osmosis happens because of diffence in concentration of water different regions.
Yes, it is slightly manitol-positive, though. It will appear a medium yellow tint and Staphylococcus aureus will contrast it by turning bright yellow. S. aureus is a better example for mannitol-positive.See Figure 5:http://www.microbelibrary.org/Culture%20Media/details.asp?id=2315&Lang=
