Bacteria...

                   Bacteria

Bacteria are small living organisms, also called microorganisms, so small that they cannot be seen with the naked eye, but can be seen using a microscope.  In 1838 the word "bacteria" originated from the Greek word "bakteria", meaning "little stick".  The reason for this is that the first discovered bacteria had a rod-like shape.

 The bacteria was first discovered in the 17th century by Van Leeuwenhoek, a Dutch scientist.  He discovered a "protozoa" (one-celled organism) and named them "animalcules".  He also improved the microscope and laid the foundation for microbiology.

 A gram of soil typically contains about 40 million bacterial cells.  A milliliter of fresh water usually contains about one million bacterial cells.  The Earth is estimated to contain at least 5 non-billions of bacteria (the number formed after zeroing 54 after 5) and most of the Earth's biomass is thought to be composed of bacteria.

 Bacteria are ubiquitous in nature which means that they can be found everywhere in the environment such as air, soil and water.  Even extremely difficult environments can be home to bacteria, such as hydrothermal vents or living within glacier lakes in Antarctica.

 Bacteria can be motile (motile) or non-motile (immobile).  Motile bacteria slip or even swim.  Bacteria can spread from one surface to another through a process called cross-contamination.

 For example, if a person has E. coli on their hands and touches the door handle, the bacteria can stick in the door handle and quickly increase the number.  The door can then act as a new location for cross-contamination.

 The bacterium reproduces through binary fission.  Binary fission is one of the common methods of reproduction in nature in which the body of an organism divides into two parts, producing offspring.  Binary fission can occur relatively rapidly under favorable conditions.

 Some bacteria, like plants, make their own energy source from sunlight (photosynthesis), while others have to absorb nutrients from their environment.  Bacteria have adapted themselves to take energy from a variety of environmental materials such as sulfur and iron.

Fact 1: Bacteria in mobile phones

Bacteria

 Mobile phones may have become an integral part of your life as well, but according to British scientists these tiny communication devices can provide a conducive environment for bacteria to grow.  Be careful if you use a smartphone.  Do you know that bacteria are also present on your mobile phone.  The number of bacteria present in the phone is more than that of your toilet seat.

Fact 2: Bacteria in purse

Bacteria

 We always think that germs are found only in places like bathrooms, drains and kitchens, then the shocking thing for them is that most germs are found in the purse of girls.  Everyone keeps notes and coins in the purse.  But these notes and coins, which enhance the purity of your purse, have the most bacteria.  There are over 2500 types of bacteria on every note in your purse.

Fact 3: body odor due to bacteria

Bacteria

 Your body odor is not due to sweat but due to bacteria.  Bacteria can survive on any part of this planet and in any climate.  When it rains, the air has a strange smell.  Do you know that this strange smell is also caused by a type of bacteria.
