Want this question answered.

. Which type of environment do microorganisms grow best. Found insideThis book reports on current research to improve the safety and nutrition of these. Bacteria does not need light to reproduce unlike plants.

Bacteria known as mesophiles which include most pathogens and common environmental bacteria grow best in temperatures ranging from 20 to 40 degrees Celsius 68 to 104 degrees Fahrenheit. Some bacteria thrive in extreme heat or cold while others can survive under highly acidic or extremely salty conditions. Two groups of thermophiles have been observed.

Specific preferences for growth are as diverse as the types of microbes. Other microorganisms known as anaerobes grow best in the absence of oxygen. Bacteria spoil food by eating it and excreting it as metabolic waste harmful for humans bacteria grow and live best in moist warm air.

Some microorganisms can grow best at a low temperature 4 to 10C and are said to be psychrophilic whereas those bacteria growing best at higher temperature from 20C to 37C are called mesophils. Multicellular microorganisms have an advantage in nature. Facultative thermophiles grow both at 37ÂC and 55ÂC.

These organisms are known as extremophiles. Be notified when an answer is posted. Some can survive under highly acidic or extremely salty conditions.

Microbes grow well within a specific range of conditions for multiple environmental variables. Request Answer. Add an answer.

Some bacteriathrive in extreme heat or cold. Bacteria can live in hotter and colder temperatures than humans but they do best in a warm moist protein-rich environment that is pH neutral or slightly acidic. In the laboratory under conditions of optimal nutrient sources temperature humidity and so on microorganisms are usually treated as individuals and are studied predominantly during the relatively small window of time in which they grow as exponential pure liquid cultures.

Thermo heat have optimum growth temperature of 45ÂC or higher and generally grow over a range of 40Â to 75ÂC. Some types of microorganisms have adapted to extreme environments and sustained colonies. Any extreme sun or light may actually hinder the process of growth for bacteria.

Warm temperatures are better for microbial growth Most of the time when temperatures become cooler the metabolism its ability to maintain life functions of the microbes slows. Overall microbes typically grow best at a specific set of conditions and less well at other conditions Figure 5. Bacillus spores can withstand boiling 100C from a few minutes to 3 hours but.

Extremophiles have been isolated from rocks as much as 7 kilometres below the Earths surface 69 and it has been suggested that the amount of organisms living below the Earths surface is comparable with the amount of life on or above. What are the best conditions for microorganisms to grow. An organism that is heat resistant for instance.

Bacteriacan live in hotter and colder temperaturesthan humans but they do bestin a warm moist protein-rich environmentthat is pH neutral or low acid. Most bacteria that cause disease grow fastest in the. Microorganisms that grow best at moderate temperatures _____________ prefer cold temperatures deep ocean water for example psychrophiles ____________ organisms prefer warm.

Most of the pathogenic non-sporing bacteria are killed at 58C to 60C for 30-60 minutes. However the natural environment.
