chemosynthetics
Yes - and vice-versa.
The question is toxic to what. Not all chemicals which are toxic to humans are toxic to bacteria, and some chemicals which are toxic to bacteria are harmless to humans (which is why we can have antibiotics). There are chemicals (like Hydrogen Sulfide) which are very toxic to mammals that SOME bacteria eat as food. But there are other chemicals like chlorine which are toxic to both humans and bacteria. So the question does not have a simple answer.
bacteria......harmless under a microscope but if i let it loose....MWHAHAHAHHA
bacteria is not harmless if there is alot of bacteria then you can get really sick.
Pollutants in the sea are not made harmless by dilution because large bodies of water have the capacity to dilute and disperse wastes :) Hope that helps you out!
There can be, yes. But they are most liekly harmless and natural.

No. Some are harmful.
Yogurt and buttermilk are fermented by a harmless bacteria added after pasteurization to prolong their shelf lives.
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.
the microorganisms can be harmful and harmless. the harmless microorganism serve a lot of use to both plants and animals. the rizobium bacteria present in the root nodules of legumes fixes atmospheric nitrogen. the lactobacillus is used in the curdling of milk. yeast is commercially used for fermentation. some of the microorganism decay the dead material. some like spirulina are used as food supplements by astronomers.
Typically, we can tolerate microorganisms, depending on the type. We have quite a few different bugs in our intestine, on our skin and in our mouths, and for the most part they do no significant harm. However, many bacteria and fungi grow a colony on a food source and produce a toxin to prevent other microorganisms from growing. Botulism food poisoning isn't actually caused by the bacteria, it's the toxin that the bacteria produces to "protect its turf." The bacteria is quite harmless and easily killed but the toxin is quite resistant. Same with yeast. It converts sugar (food source) into alcohol as a toxin to protect it's turf. Same with Penicillin and almost every microorganism you can imagine. In reality, we could not live without microorganisms, and while most are harmless, some are even beneficial, and some can make you quite ill or even kill you.

"Although you might not like to think about it, millions of microorganisms, including bacteria, are living on the surface of your skin. Most of the time they are harmless, but, if you get a cut or even an insect bite everyday bacteria may take the opportunity to slip under the skin and cause an infection." source: http://www.healthology.com/skin-problems/skin-problems-information/article1216.htm
Biodegradable pollutants:Those pollutants which can be broken down into simpler, harmless, substances in nature in due course of time (by the action of micro-organisms like certain bacteria) are called biodegradable pollutants. Domestic wastes (garbage), urine, faecal matter, sewage, agriculture residues, paper, wood, cloth, cattle dung, animal bones, leather, wool, vegetable stuff or plants are biodegradable pollutantsNon Biodegradable Materials:Those pollutants which cannot be broken down into simpler, harmless substances in nature, are called non-biodegradable pollutants. DDT, plastics, polythene, bags, insecticides, pesticides, mercury, lead, arsenic, metal articles like aluminum cans, synthetic fibres, glass objects, iron products and silver foils are non-biodegradable pollutants.
bacteria cause many diseases in plants and animals bacteria are also cause of food spoilage
No, cooking does not take bacteria out of meat. Cooking kills bacteria so that it is harmless when eaten.

Aids.
of course there are many harmless and useful bacteria that our live depend on
Yes, but most are weak and almost harmless.
There are 3 main types of micro-organism, fungi, bacteria and viruses. The most useful is perhaps fungi, the most well known being penicillin which is basically mould! And of course there are many types of harmless bacteria (as well as the more nasty types)which are involved in keeping us healthy.
