What are the factors that affect fermentation rate?
Factors that affect fermentation rate include temperature, pH levels, type and concentration of yeast or bacteria, nutrient availability, and oxygen availability. Lower temperatures generally slow down fermentation, while higher temperatures can speed it up. Different strains of yeast or bacteria may have differing fermentation rates based on their characteristics.
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.
How might the pH level of the stomach inhibit growth of ingested bacteria?
Many bacteria doesn't support a very low pH.
Pathogenic foodborne bacteria grow best in food with a pH of?
Pathogenic foodborne bacteria grow best in food with a pH above 4.6. This pH level provides an environment conducive for their growth and reproduction. Foods with a pH below 4.6 are generally considered less favorable for the growth of these bacteria.
Which pH is ideal for the growth of bacteria in food 6.0?
6.0
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.
How can honey ferment and what are the factors that influence the fermentation process?
Honey can ferment when exposed to yeast and bacteria, which consume the sugars in the honey and produce alcohol and carbon dioxide. Factors that influence the fermentation process include temperature, moisture content, pH level, and the presence of wild yeast and bacteria.
What is the pH level in yeast fermentation?
Yeast fermentation typically results in a decrease in pH level due to the production of acids such as lactic acid and acetic acid. The exact pH level can vary depending on factors such as the type of yeast used, the fermentation conditions, and the initial composition of the substrate.
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 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
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 pH range for growth of a yeast?
The optimal pH range for yeast growth is typically between 4 and 6. Yeasts are able to tolerate a slightly broader pH range, from 3 to 8, but their growth is most efficient within the optimal range. pH outside of this range can affect yeast metabolism and growth rate.
