Because some bacteria are anaerobic (do not need oxygen to survive). In humans and other aerobic organisms, cyanide prevents cells from respiring (turning oxygen and glucose into energy) so they run out of energy and die. Anaerobic bacteria produce energy in other ways, so cyanide doesn't harm them. (:
What else can I help you with?
Are ionized particles harmful?
Some are and some are not. One negative ion, the chloride ion, is generally harmless. Another negative ion, the cyanide ion, is highly toxic.
Fermented by harmless bacteria added after pasteurization?
Yogurt and buttermilk are fermented by a harmless bacteria added after pasteurization to prolong their shelf lives.
Is it true that pathogenic bacteria out number helpful bacteria?
Yes, but most are weak and almost harmless.
Is KCN broth selective?
Yes, KCN broth is selective because it contains potassium cyanide as an inhibitor, which selects against organisms that cannot metabolize cyanide. This makes it useful for isolating cyanide-resistant bacteria.
Why is mold not healthy?
Mold is fungus and bacteria that have been growing. While many are harmless, some can be very dangerous to humans and some can even cause death as it can be toxic.
How could bacteria be harmless but annoying?
bacteria is not harmless if there is alot of bacteria then you can get really sick.
Are ionized particles harmful?
Some are and some are not. One negative ion, the chloride ion, is generally harmless. Another negative ion, the cyanide ion, is highly toxic.
Fermented by harmless bacteria added after pasteurization?
Yogurt and buttermilk are fermented by a harmless bacteria added after pasteurization to prolong their shelf lives.
Explain how the bacteria in griffith's experiment were transformed?
The harmless living bacteria took in pneumonia-causing DNA(genes) from the heat-killed, pneumonia-causing bacteria, as a result of which the harmless bacteria changed into bacteria that cause pneumonia.
Is spoilage bacteria always harmless?
Yes
Does yogurt contain virus?
Yes, it contains some algae bacteria. But it is completely harmless to humans. The Bacteria is actually good for you and is also found in cheese as well.
Harmless bacteria produced colonies with what edges?
smooth
Is it true that some bacteria are not pathogens?
Yes, it is true that not all bacteria are pathogens. In fact, the majority of bacteria are harmless or even beneficial to humans and other organisms. Only a small percentage of bacteria are pathogenic and can cause disease.
Why is potassium cyanide toxic to humans but nutritional to some bacteria?
because it multiplies in human cells eventually shutting down important processes. It is nutritional to the bacteria because it multiples in the host but it is aneraerobic.
Are bacteria more harmful than virus?
No. Actually, it would be more accurate to say that you really can't compare the two; some bacteria and some viruses are harmless, some of each will make you sick, and some of each are deadly.
Is it true that pathogenic bacteria out number helpful bacteria?
Yes, but most are weak and almost harmless.
Is it true that 99 percent of bacteria is helpful?
No. 70% of bacteria is harmless, whilst the other 30% is harmful.
