Not sure why that is, but anyways...he received an authorization or comcheck for his first week of work ..... and I've NEVER heard of this, so I'm pretty confused. He filled out the check with his name and the amount, then called a number to register it.
Bacteria can be divided into following types on the basis of use of oxygen: Aerobic: which require oxygen for their growth they can be: a. Obligate Aerobic: survive only if oxygen is present example; Mycobacterium tuberculosis. b. Microaerophile: That require lower amount of oxygen i.e. 2 to 10% example; Helicobacter pylori. 2. Anaerobic bacteria; which do not require oxygen for their growth they can be; a. Obligate Anaerobic; which are harmed by presence of oxygen , they can not survive in presence of oxygen. Example: Clostridium tetani, C. perfringens. b. Facultative anaerobic bacteria; can grow without oxygen, but use oxygen if it is available to produce energy.
O2 REQUIREMENTS & CULTURING ANAEROBIC BACTERIA. An excellent way to determine the oxygen needs of your bacterium is to grow it in different. oxygen environments---atmospheric oxygen of 22%, no oxygen at all (G asPak jar), a nd. reduced oxygen at less than 10% (c andle jar)--and compare the qualitiy and quantity of. growth.
