Bacteria

Chlorine kills bacteria their for it will clean and disinfect your pool or hot tube

Coliforms can survive in cold temperatures but may not thrive in freezing conditions. Some coliform bacteria are able to survive and remain viable in freezing temperatures, while others may not be able to grow or reproduce until temperatures warm up. It is important to note that freezing may not completely eliminate coliforms, so proper sanitation measures are still necessary.

Pasteurella is not considered fastidious. It can grow on standard laboratory media with no special nutritional requirements. It is a fastidious bacterium.

The beneficial microorganisms that give unique flavor to fermented foods like kimchi and yogurt are typically lactic acid bacteria, such as Lactobacillus and Bifidobacterium. These bacteria ferment sugars in the food, producing lactic acid, which gives the characteristic tangy flavor. Additionally, other microorganisms like molds and yeasts can also contribute to flavor development in fermented foods.

Bacteria can double every 20 minutes under ideal conditions, so it would take about 6-7 cycles of doubling for bacteria to go from 1000 to 1000000. This would roughly translate to around 2-3 hours for bacteria to increase from 1000 to 1000000.

Alexander Fleming hypothesized that the yellow-green mold, known as Penicillium notatum, released a substance that inhibited the growth of certain bacteria, such as Staphylococcus aureus. This substance was later identified as penicillin, the first antibiotic discovered. Fleming's work laid the foundation for the development of modern antibacterial drugs.

Neutrophils are typically increased in response to a bacterial infection. They are the first responders of the immune system and phagocytize bacteria to help eliminate the infection.

On nutrient agar, Yersinia appears as smooth, opaque colonies with a pale yellowish color. On EMB agar, colonies may show greenish metallic sheen due to lactose fermentation. On MacConkey agar, Yersinia typically forms colorless to pale pink colonies due to its inability to ferment lactose.

These are not parasites. These are autotrophs and make their own food just like plants do except they use chemicals instead. There are methanobacteria, sulfur bacteria which live along deep sea hydrothermic vents, and nitrogen bacteria.

For long-term storage, it is recommended to use a specialized cryoprotectant like glycerol and freeze the bacterial isolate at temperatures below -70°C in a dedicated freezer, such as a ultra-low temperature freezer. This method helps prevent ice crystal formation and maintain cell viability during storage, which is necessary to preserve the isolate effectively. Simply growing the bacteria in a broth with glycerol and storing in a normal freezer may not provide the necessary conditions for long-term preservation.

not necessarily- temperature below the bacteria functioning temperature will already retard them- just anywhere lower than its average temp. Take yourself as a comparison. If you were in a colder temperature than your body temperature (and normally a lot lower, will the temp make you shiver and slower you down, ven your thinking

Bacteria can theoretically grow at all temperatures between the freezing point of water (32 degrees F) and the temperature at which protein or protoplasm coagulates. Temperatures below the freezing point slow their growth, but it will not kill them. Heat treatments of 158 degrees F for 15 seconds will kill many of them, but spore-forming organisms require live steam (212 degrees F) for 30 minutes.

Bacteria generally dislike extreme temperatures, high levels of acidity or alkalinity, lack of nutrients, and exposure to harmful chemicals or antibiotics. These conditions can inhibit their growth and survival.

The ICD-9 code for gram-negative bacteria is 041.4. It is used to indicate infections caused by gram-negative bacteria in the coding system.

ESBL infections are typically treated with antibiotics that are not affected by the ESBL enzyme, such as carbapenems. However, the choice of treatment can vary depending on the specific strain of bacteria causing the infection. Consultation with a healthcare provider is essential for proper diagnosis and treatment.

The presence of bacteria in dental unit waterlines was first reported in the late 1970s and early 1980s. Studies found that dental waterlines were contaminated with various microorganisms, including potentially pathogenic bacteria.

round cells are round discs with two large dimples at each side, and they are known as red blood cells. Their job is to carry oxygen to all your cells. The rounded shape gives extra surface area for picking up and carrying oxygen.

You will test it by before wiping the doorknob with the antibacterial wipe, use a cotton swab and wipe it around the door knob.... use agar and wipe the swab into a petri-dish with the agar. After wiping the doorknob using the antibacterial wipe, use another cotton swab to wipe the doorknob then wipe it into another petri-dishagar= helps grow

Yes, spirilla bacteria can get energy through various methods such as photosynthesis, chemosynthesis, or by breaking down organic matter through fermentation or respiration.

There are primarily four types of bacteria found in the reticulo-rumen of ruminants like cows and goats: cellulose-digesting, hemicellulose-digesting, starch-digesting and lactate-utilizing bacteria.

Neisseria gonorrhea is typically curable and causes no long-lasting effects is treated promptly. Antibiotic resistance is an increasing problem, so patients must follow instructions for treatment.

Bacteria reproduce rapidly, with some species able to double their population every 20 to 30 minutes under ideal conditions. This exponential growth results in a graph that shows a steep upward curve as the population increases over time.

Bacillus mesentericus is a bacterium commonly found in soil and the intestinal flora of animals. It is known for its ability to produce endospores that are resistant to harsh conditions, allowing the bacterium to survive in various environments. Some strains of B. mesentericus have been used in food fermentation processes, but it is important to note that not all strains are safe for consumption.
