Some bacteria are metabolically active in hot springs because?
Some bacteria are metabolically active in hot springs because they have adapted to survive and thrive in extreme temperatures. These bacteria have enzymes and metabolic pathways that are stable at high temperatures, allowing them to carry out processes like photosynthesis or chemosynthesis even in these harsh conditions.
Why don't all bacteria die during the cooking process?
Different species of bacteria have different sensitivity to high temperatures. Fortunately practically all species of bacteria that can cause food poisoning are killed by temperatures less than 160F and most of the rest can be killed by the high pressure canning temperatures around 240F to 250F. A few species of bacteria can actually survive and grow in the high pressure, high temperature (up to 600F), high radioactivity environment inside pressurized water nuclear reactors! Most of these species of bacteria feed on metal ions not organic material and can be a serious cause of corrosion and maintenance problems in such reactors.
Bacteria generally grows well in foods that?
contain protein, are moist, and are neutral to slightly acidic.
Where can't bacteria survive?
I don't know because thay live every where. Bacteria can't live in the freezer or in an active microwave. A clean kitchen has to be kept very hot or very cold to stay clean. Bacteria multiply faster in temperatures from 10-60 degrees Celsius but otherwise they can live just about anywhere.
How do you Kill Halophilic Bacteria?
Halophilic bacteria thrive in high salt environments, making them challenging to eliminate. Effective methods for killing halophilic bacteria include using high concentrations of salt, desiccation, high temperatures, and disinfectants. It is essential to identify the specific type of halophilic bacteria and choose the appropriate method for eradication.
Does temperature affect bacteria growth?
bacteria grows best at warm temperatures. it has been proved. but if it gets too high (cooking temperatures) it may be killed. that probably has been proved but i am not aware. hope this help. i <3 webkinz
What temperature kills the most bacteria?
High temperatures kill the most bacteria. These temperatures should be at least 160 degrees Fahrenheit in foods like many meats.
Why are some bacteria metabolically active in hot springs?
Their enzymes have high optimal temperatures.
What is the difference between thermophilic and thermoduric bacteria?
Thermophilic bacteria have growth temperatures that range from 45C to 85C, with an optimum temperature of about 60C. Thermoduric organisms can survive at extreme temperatures, e.g. pasteurization, but cannot grow.

Some bacteria are metabolically active in hot springs because they have adapted to survive and thrive in extreme temperatures. These bacteria have enzymes and metabolic pathways that are stable at high temperatures, allowing them to carry out processes like photosynthesis or chemosynthesis even in these harsh conditions.
How do different temperatures affect bacteria?
Different temperatures can affect bacteria in different ways. Extreme temperatures (too hot or too cold) can kill bacteria by denaturing their proteins and disrupting their cell membranes. Optimal growth temperature varies between bacteria species; some thrive in high temperatures (thermophiles), while others prefer moderate temperatures (mesophiles). Cold temperatures can slow down bacterial growth but may not necessarily kill them.
What do high temperatures do to lactobacillus casei?
It will bake the culture, and denature the proteins in the bacteria, turning them hard.

What are thermophiles?
A thermophile is an organism - a type of extremophile - which thrives at relatively high temperatures, between 45 and 80 °C[1] (113 and 176 °F). Many thermophiles are archaea. Thermophilic bacteria is a extreme heat loving bacteria that is a member of the archaebacteria kingdom.

Effective methods for killing halophilic bacteria include using high concentrations of salt, desiccation, high temperatures, and disinfectants.
