Do desiccation has a static or cidal effect on microorganism and indicate why?
Desiccation has a static effect on microorganisms, meaning it inhibits their growth and metabolic activity but does not necessarily kill them. This occurs because dehydration disrupts the microbes' essential functions and limits their ability to reproduce or carry out cellular processes. Resuming water availability can potentially allow the surviving microorganisms to reactivate and resume activity.
How does sugar preserve food?
Sugar preserves food by lowering the water activity (aw). If the aw is 85 or less, spoilage and pathogenic microorganisms can't grow. Microorganisms all need proper food, water, temperature and acidity to grow and adding sugar to appropriate levels can prevent bacterial growth.
Does freezing streile water?
Freezing sterile water will not kill any microorganisms that may be present in the water. Freezing can actually preserve these microorganisms until the water is thawed. To eliminate microorganisms, water needs to be sterilized through methods such as boiling or using chemical disinfectants.
What are the Microorganisms that live in pond water?
Pedo bear
How can you purify water that has been contaminated with salt and microorganisms?
You can separate the water from the mixture through evaporation.
What is the water activity in honey?
The water activity in honey is typically around 0.6, which is too low to support the growth of most microorganisms. This low water activity helps give honey its long shelf life and resistance to spoilage.
What is required for life activity?
Oxygen, water, and life is required for life activity. Also ap-ma-spere<-(i couldn't spell it) is required, maybe...
What is the water activity value for milk?
0.95 or above
Why microorganisms have a hard time with salt?
Salt absorb water and without water microorganisms are killed.
Why is it free from diseases and microorganisms?
why ground water free from diseases and microorganisms?
How does drying apples help preserve them?
By drying apples, or any food item, you reduce the water activity which will help prevent or slow the growth of spoilage microorganisms or pathogens.
Does drying apples help preserve them?
By drying apples, or any food item, you reduce the water activity which will help prevent or slow the growth of spoilage microorganisms or pathogens.
What conditions are needed to biodegrade?
Biodegradation requires the presence of microorganisms (such as bacteria and fungi) that can break down organic matter, as well as water, oxygen, and a suitable temperature for the activity of these microorganisms. The process can be affected by factors such as pH, nutrient availability, and the complexity of the material being degraded.
What microorganisms live in salt water?
Many microorganisms are found naturally in fresh and saltwater.
What is water activity?
Water activity is a measure of the amount of water available for biological reactions and microbial growth in a substance. It is calculated as the ratio of water vapor pressure in the substance to the vapor pressure of pure water at the same temperature. A lower water activity value indicates less available water for microbial growth.
Why isn't water used to preserve microorganisms in the lab?
All of the microorganisms would absorb the water, and become corrupted because of the microorganism's that water itself contains.
What did you learn about pond water?
It is water in a ditch with many microorganisms in them.
