Why would lemon juice be an effective way to kill bacteria?
Most bacteria as well as our cells work best at certain pH levels. Lemon juice has a pH of around 2. Our body has a pH around 7.4. Most bacteria prefer a pH of 7.
Does caustic kill bacteria?
yeah, creating a high pH environment (pH>13), caustic kills almost all bacteria.
How might the pH level of the stomach inhibit growth of ingested bacteria?
Many bacteria doesn't support a very low pH.
List the various requirements needed for culturing bacteria?
The requirements in culturing bacteria is the right temperature, gas, pH and moisture to assure proper growth of bacteria.
What affects the elimination of bacteria from an object?
Temperature, pH, Number of bacteria present and presence of organic matter
What is the pH level in yeast fermentation?
what is the pH level of yeast?
Why fo you get BV after a yeast infection?
Bacterial Vaginosis and yeast infections often go hand-in hand, it's very common to have both infections at once. Your vagina is acidic to kill 'bad' bacteria and help the 'good' bacteria (such as the bacteria that help keep yeast under control) thrive, if your vaginal pH is off-balance it's normal to develop overgrowth of 'bad' bacteria and as the 'good' bacteria is reduced yeast is also allowed to thrive.
What is the medical term meaning condition also known as vaginal thrush or a yeast infection?
The vagina naturally contains bacteria and yeast, an acidic pH kills 'bad' bacteria and allows 'good' bacteria to thrive - some of this 'good' bacteria produces hydrogen peroxide to keep yeast under control. Sometimes vaginal pH and flora can be thrown off balance, making it easier for yeast to multiply - for example if a woman uses soap to wash her vulva, this can change pH so cause imbalance in vaginal flora. Yeast is also a fungus so likes warm moist environments, thus things like women wearing tight synthetic clothing can increase risk of developing a yeast infection, and yeast like sugar so a high-sugar diet can increase yeast infections too.
What it means a day after getting off your period your vaginal feel irritated and very itchy?
Itching and irritation are most commonly a result of a yeast infection. You naturally have yeast within the vagina, but an acidic pH allows healthy bacteria to thrive which produce hydrogen peroxide that keep yeast under control - during menstruation the menstrual flow changes vaginal pH which in turn can change bacteria and allow yeast growth. If you use products like commercial pads these prevent air-flow making the area more favorable to yeast growth.
Can medication cause thrush?
Good question, but not usually. The common medicines that can cause yeast infections are antibiotics. Your vagina has a very tempermental pH balance of good bacteria and yeast. Both are there all the time, the yeast grows and the good bacteria eats it. They naturally maintain a healthy level of each. However, when you take antibiotics, this medicine kills off any kind of bacteria, even the good kind living in your vagina. Now, this is good because it will kill the infection for which it was prescribed, but will also kill off good bacteria- leaving nothing to balance out the yeast. The yeast builds up and causes a yeast infection. Pain killers shouldn't disrupt the balance of yeast and good bacteria so you should be safe.

What is the pH range for growth of a yeast?
optimum pH 5-6
What is the pH of Saccharomyces cerevisiae?
Yeast grows best in a neutral to slightly acidic environment. The pH inside a yeast cell is held relatively constant at around 5.5 and as long as this can be maintained the external pH doesn't matter too much. The ideal pH for fermentation is probably closer to 4.0. Not because of yeast's preferences but because bacterial growth is seriously inhibited at this pH.
Can soap give you yeast infection?
No, soap will not kill yeast. A woman can now buy over the counter yeast infection medicine without a prescription. The medicine can be bought at any drug store or retail store such as Walmart.
When yeast is in bread what PH is the best?
nothing
What conditions does yeast need to grow in?
Most bacteria will grow in dark, moist, warm areas with a neutral PH balance (ph7, water, sweat, most foods) and a source of food for the bacteria, such as sugars, and protein. All bacteria need to grow in conditions such as this is time. (And not very long, either. 4 hours on average)
How does pH effect yeast fermentation?
Bakers yeast (also known as Brewer's yeast -- it's the same organism) is a single-celled microorganism. It thrives when the pH is slightly acidic -- pH 4.5 is best. However, it will grow over a wide range, even when the pH is slightly basic. However, it will slow down as the pH gets farther from 4.5. If the pH gets too acidic or too basic, the yeast just won't grow. For bakers, the last point is the most important. A neutral to slightly acid pH will give the fastest rate of fermentation, all other things being equal. Luckily, for breadmakers, this isn't a problem unless you start adding exotic ingredients to the mix. Yeast does just fine with the pH of most bread recipes. For breadmaking, the temperature of the rise is more important than the pH.
What is the difference between bacterial vaginosis and a yeast infection?
Bacterial vaginosis and yeast infection are both the results of imbalances in the normal flora of the vagina. A yeast infection involves an overgrowth of candida and related species. Odor is not a huge complaint of women with yeast. Symptoms may include redness and discomfort. The vaginal pH is normal. In contrast, bacterial vaginosis is a death of the protective bacteria in the vagina. Odor is a common complaint, but inflammation and irritation are not. The vaginal pH is usually higher than normal.
