simple media :- is a general media used to grow normal microbes in environment & is named as nutrient agar. it is non selective media. complex media :- is used to grow heterotrophic organisms. it is selective.
Differential media
he because the island was used as an anthrax testing ground and there is anthrax in the soil on the island
Anthrax spores were used in bioterror attacks in the US in 2001, where letters containing the spores were mailed to different locations, resulting in several individuals being infected with anthrax.
Aerobic culture media contains oxygen and is used to grow organisms that require oxygen to grow, while anaerobic culture media is oxygen-free and is used to grow organisms that can only survive in the absence of oxygen. The choice of media depends on the type of microorganism being cultured and its oxygen requirements.
Robert Koch is associated with Koch's postulates, which must be satisfied before it can be accepted that particular bacteria cause particular diseases. He was first published in 1876. He did his first work with Anthrax. Later he developed methods using media like potatoes and later with Petri used what is still being used to grow bacteria, Petri dishes.
Anthrax can be used as a biological weapon as only 100gms. of Anthrax released over a major city may cause up to 3 million casualties.
It grows in Thio - anaerobically.
The bacteria that cause anthrax may be used as a type of biological warfare, since it is possible to become infected simply by inhaling the spores, and inhaled anthrax is the most serious form of the disease.
To inoculate a solid media, a sterilized inoculation loop or needle is used to pick up a small amount of the desired culture. This culture is then streaked onto the surface of the solid media in a specific pattern to ensure isolated colonies grow. The inoculated media is then incubated at the appropriate temperature to allow the colonies to grow.
Several high-profile individuals have been targeted with anthrax through the mail, including American media outlets such as NBC and CBS, as well as politicians like Senators Tom Daschle and Patrick Leahy. These incidents occurred in the wake of the September 11th terrorist attacks in 2001, sparking a national anthrax scare.
they are those organisms that are used to grow anaerobes so they can decreaes the amount of oxgyen present
