Does a high coliform count indicate that the water may contain more than one kind of disease causing organism?
A high coliform count indicates that the water is contaminated by feces.
Why are jams and jellies not attacked by bacteria and fungi?
There is enough sugar in jams to dehydrate bacteria, so that it can't grow. Molds are not limited in this way. The sealing of jam helps to keep molds, as well as dirt and dust, away from the jam.
Why does bacteria doesn't grow in jam?
It depends on the amount of sugar in the jam. Honey is almost pure sugar and nothing grows on it. It has been found in tombs. It has lost it's water and it is in a crystal but with water added it is just like it was. The high sugar "sucks'" the water out of the bacteria and it dies.
Which of the following can cause excess growth of algae in water Large amounts of fecal coliform High nitrate content All of the above High phosphate content?
All of the above can cause excess growth of algae in water. High nitrate and phosphate content can act as nutrients for algae growth, while large amounts of fecal coliform indicate high levels of organic matter, which can also contribute to algae proliferation.
Can candied fruit kept in the fridge grow mold?
Yes, candied fruit can still grow mold in the fridge due to the high sugar content creating a moist environment. To prevent mold growth, make sure the candied fruit is properly stored in an airtight container and used within a reasonable timeframe.
Why high coliform counts in process meat?
high coliform counts in processed meat come from contaminations from handlings and surroundings.
Why does soda make mold grow faster?
Soda contains sugar, which provides a food source for mold to grow. The carbonation in soda also creates an acidic environment that can promote mold growth. Additionally, the dark and moist environment inside a soda bottle can create ideal conditions for mold to thrive.
Does a high coliform count indicate that the water may contain more than one kind of disease causing organism?
A high coliform count indicates that the water is contaminated by feces.
If a high coliform count is an indicator that the water may contains what?
sewage
What is a coliform count of water?
Coliforms are rod shaped gram negative bacteria that are often in well water. Not all coliform are harmful, but those of fecal origin are very harmful. The lab coliform count determines what type and how many coliform are in a water sample. This result is always marked "fit for human use" or "NOT fit for human use".
Can sugar cause the growth of mold?
In general, mold doesn't grow when there is a high concentration of sugar. That being said, mold will grow wherever the conditions are right. Mold can grow when sugar is present if it has enough moisture and the temperature is right, however it usually the starches found in relation with sugar that the mold will find more palatable.
Does water or coke make mold grow faster?
Water would typically make mold grow faster than coke because water provides a more suitable environment for mold to thrive, with its higher moisture content. Coke, being acidic and containing sugars, might slow down mold growth due to its less hospitable environment for mold spores.
Does sugar kill bacteria?
the concentration of sugar in the bacteria is low whereas that of the outside, where the sugar is, is high. to make the concentration balanced, water molecules have to leave the cells of the bacteria therefore causing the bacteria to shrink and eventually die. (sorry if the answer is too long) this process is called "hypertonic"
What is a too high count of coliform in well water?
There is a certain amount of coliform in a lot of well water. -The difference is ' Escheria Coli.' Get your well water analysed if you suspect this. E Coli comes mostly from wells in fields where animals graze and defecate.
How does jam last for months?
Due to the high sugar content, the water activity is so low that bacteria will not grow. However, if given the opportunity, molds will grow on the surface.
Why are jams and jellies not attacked by bacteria and fungi?
There is enough sugar in jams to dehydrate bacteria, so that it can't grow. Molds are not limited in this way. The sealing of jam helps to keep molds, as well as dirt and dust, away from the jam.
What is the average fecal coliform count for raw sewage?
The average fecal coliform count in raw sewage can vary widely, typically ranging from 10^5 to 10^7 colony-forming units (CFU) per 100 milliliters. This high concentration reflects the presence of fecal matter and is used as an indicator of potential pathogens in water. It's important for treatment processes to reduce these levels before wastewater is released into the environment.
