Bioremediation of contaminated sites is rarely performed in nature under ideal growth conditions for bacteria. Extremophiles can grow at extreme values of temperature, pH, ionic strength and metal concentrations
Each of the following bacterial lifestyles exposes the bacteria to an environment that requires special evolutionary adaptations to survive. In each case, explain what adaptations were required for the bacteria to live in that environment, and describe ho ...

Mouth bacteria grow fast in airless conditions.Oxygen rich saliva (唾液) keeps their numbers down.When we sleep,for example,the saliva stream slows,and sulfur (硫) producing bacteria gains the upper hand,producing classic “morning breath”. Alcohol drinking,too much talking,breathing through the ...
Normal gut motility helps prevent overgrowth of bad bacteria. The most likely source of infection for foals is another horse, perhaps an asymptomatic shedder, or even their dams. Signs of Salmonella diarrhea Mild to severe and possibly bloody diarrhea Rapid dehydration accompanied by h...
The addition of carbon source promotes the heterotrophic bacteria to reduce the organic matter and assimilate the nitrogen waste into microbial protein. The C:N ratio was maintained at 15:1 for the development of biofloc and addition of urea for nitrogen source. Biofloc samples were collected ...
Our analysis determined confident functions for both of these proteins (see below). Fig. 1 Basic characterisation of proteins encoded by the minimal bacterial genome. a Orthologues identified in bacteria. Results for each functional class are represented by a different colour: gold for the Unknown ...
Is sugar cane easy to grow? Yes, it is simple to propagate and grow this crop in general. Still, productive cultivation demands optimum growing conditions for sugar cane. The plant needs a high level of solar radiation and heat to flourish. Active hydration is another requirement for sugar ...
The environmental conditions required for anaerobic respiration are lack of oxygen, availability of glucose, and the presence of enzymes necessary to... Learn more about this topic: Types of Bacteria Found in Anaerobic Environments from Chapter 5/ Lesson 3 ...
The culture medium of the present invention has been used to grow a biologically pure culture of a new strain of bacteria designated MS-1. MS-1 is a magnetotactic Aquaspirillum. A non-magnetic variant of the stain may be cultured from MS-1 with a growth medium lacking iron or when the ...
