bacteria - one of the most undemanding beings in the world, created by nature.And I must say, she tried, investing in these microorganisms unsurpassed safety factor: the ability to survive in a variety of environments.They were uneasy and a wide range of temperatures and acidic environment they can live deep underground and under water, in the sky, and even in space, in a vacuum.And in harmful environment, microorganisms do not die, and to create a special form of existence.
bacterial spores
It - adaptation to adverse conditions: a change in humidity, lack of nutrients, aging culture temperature changes.A kind of "life insurance".Spores of bacteria are used for the safety of family and not an instrument or method of reproduction.Unlike fungal spores which are also for these purposes.In this state, the bacterium can persist "canned" a lot of years.And then, when the environmental conditions are favorable, the spores of bacteria are to bacteria could again form a culture.
Various
Different bacterial spores differ in shape, and location in the cell.So, hay bacillus, for example, they are centered and do not exceed the diameter.And tetanus toxoid - spherical shape and arranged at the end (the diameter exceeds the diameter of the forming cells).But in any case, the debate in bacteria are used to in order to "survive" in a hostile environment.
How are?
Many microbial spores can be formed intracellularly.They are called endospores.A microbe that created the dispute is referred to as sporangia.Some bacteria can also be formed exospores and cysts.In these cases, the microorganism itself covered with a protective sheath.It is known that in a dispute suspended metabolism and chemical composition, it is different from most bacteria (water therein is virtually absent).
How to get rid of?
current scientific knowledge that the disputes in bacteria serve to better preservation of these organisms are carried in medicine and medical practice to improve the sterilization of instruments during operations.The spores, which form infectious agents, can also get, for example, wound and cause infection.Therefore, to achieve sterility is necessary to get rid not only of the bacteria themselves, but also on the dispute.Do it with special autoclaves, which are supported by the high pressure and temperature.
