A microbe isolated from an environmental sample grows on a medium composed of agar and a mix of salts. The agar is not digested during incubation. The growth rate decreases in low CO2 conditions. The organism is likely a(n)

Autotroph.

Halophile.

Heterotroph.

Chemotroph.

The answer can not be determined from the infrmation provided.

Expert Solution

Autotroph is the answer.

Autotroph is defined as the mode of nutrition in which the organism makes their own food by itself.

Heterotroph is the organism which depend on another organism for mode of nutrition.

It is given that the organism growth rate decreases in low CO2. But it is higher in presence of high CO2 level. That's why organism is an autotroph.

Incubator is an enclosed apparatus whose internal environmental is isolated from ambient environment. This is to create favorable environment hatching chicken eggs or any other bird eggs. All incubators have one thing in common; it regulates the temperature, humidity and provides adequate oxygen supply in addition to turning eggs on a regular basis for 21 days. The main functions of the incubator are: • Egg turning: this is very important to prevent egg mortality. For egg turning, an egg holding...

By definition, an infection results from a parasitic relationship between a microbe and its host. That is, harm is being done to the host. Inapparent infection (also called subclinical, or asymptomatic infection) does not result in overt disease. How is it possible for an infection not to result in overt disease?

Wild-type E. coli can grow on minimal medium. You have isolated a mutant strain of E. coli that grows poorly in minimal medium that contains lactose and arabinose and lacks glucose. In ONPG-containing minimal medium lacking glucose the mutant strain produces very low levels of b-galactosidase activity in both the absence and presence of IPTG. The strain does not grow well when transformed with a plasmid containing the lacZ and lacY genes. The strain also does not grow well when...
