Difference between bottom and top fermenting yeast?
Asked by Wiki User
Yeast are single-celled microorganisms that reproduce by budding. They are biologically classified as fungi and are responsible for converting fermentable sugars into alcohol and other byproducts. There are literally hundreds of varieties and strains of yeast. In the past, there were two types of beer yeast: ale yeast (the "top-fermenting" type, Saccharomyces cerevisiae) and lager yeast (the "bottom-fermenting" type, Saccharomyces uvarum, formerly known as Saccharomyces carlsbergensis). Today, as a result of recent reclassification of Saccharomyces species, both ale and lager yeast strains are considered to be members of S. cerevisiae.
Top-Fermenting Yeast
Ale yeast strains are best used at temperatures ranging from 10 to 25°C, though some strains will not actively ferment below 12°C (33). Ale yeasts are generally regarded as top-fermenting yeasts since they rise to the surface during fermentation, creating a very thick, rich yeast head. That is why the term "top-fermenting" is associated with ale yeasts. Fermentation by ale yeasts at these relatively warmer temperatures produces a beer high in esters, which many regard as a distinctive character of ale beers.
Top-fermenting yeasts are used for brewing ales, porters, stouts, Altbier, Kölsch, and wheat beers.
Bottom-Fermenting Yeast
Lager yeast strains are best used at temperatures ranging from 7 to 15°C. At these temperatures, lager yeasts grow less rapidly than ale yeasts, and with less surface foam they tend to settle out to the bottom of the fermenter as fermentation nears completion. This is why they are often referred to as "bottom" yeasts. The final flavour of the beer will depend a great deal on the strain of lager yeast and the temperatures at which it was fermented.
Some of the lager styles made from bottom-fermenting yeasts are Pilsners, Dortmunders, Märzen, Bocks, and American malt liquors.
What is the word root for pertaining to the heart beat?
Asked by Shan1985
The word root for pertaining to the heart beat is "cardio-" which derives from the Greek word "kardia", meaning heart, and "pulse", meaning rhythm or beat.
Does age affect pulse rates?
Asked by Wiki User
Yes, age can affect pulse rates. Generally, younger individuals have higher resting pulse rates, which tend to decrease as a person ages. However, individual factors like fitness level, health status, and medication can also influence pulse rates.
What is the heart beat for a eight nine yr old male?
Asked by Wiki User
The average heart rate for an 8-9 year old male is around 85-100 beats per minute at rest. However, individual heart rates can vary depending on factors such as fitness level and overall health. It is always best to consult with a healthcare provider for personalized information.
Why does relaxing decrease your heart rate?
Asked by Wiki User
When you relax, your body activates the parasympathetic nervous system, which is responsible for rest and relaxation. This system helps to slow down your heart rate by releasing acetylcholine, a neurotransmitter that decreases the firing rate of the heart's pacemaker cells. This results in a lower heart rate as your body shifts into a state of calm and rest.
Why would your body flutter or shake inside?
Asked by Wiki User
Internal fluttering or shaking could be due to various reasons such as anxiety, stress, caffeine intake, or hormonal imbalances. It can also be a symptom of medical conditions like hyperthyroidism or anemia. If you experience these symptoms frequently, it's best to consult a healthcare professional for proper diagnosis and treatment.
What do you know about heart systole?
Asked by Wiki User
Heart systole refers to the phase of the cardiac cycle when the heart muscle contracts to pump blood out of the chambers (ventricles) into the circulatory system. This contraction leads to an increase in blood pressure within the arteries, pushing blood to the rest of the body. Systole is typically followed by diastole, the relaxation phase of the heart.
What is absence of ventricular electrical activity called?
Asked by Rochelleloy
Absence of ventricular electrical activity is called asystole. Asystole is a serious condition where the heart stops beating effectively, leading to a lack of blood flow and oxygen to the body's vital organs. It is considered a medical emergency requiring immediate intervention such as cardiopulmonary resuscitation (CPR) and advanced cardiac life support (ACLS) protocols.
Can people who eat a large amount of fat get heart disease?
Asked by Wiki User
Yes, consuming a high amount of fat, especially saturated and trans fats, can increase the risk of heart disease by raising cholesterol levels and contributing to the buildup of plaque in the arteries. It's important to maintain a balanced diet and limit intake of unhealthy fats to protect heart health.
