No. A toxin is what you are thinking about. Bacteria are microbes and some produce toxins and some do not.

The enzyme, catalase, is produced by bacteria that respire using oxygen, and protects them from the toxic by-products of oxygen metabolism.
Antibiotics, it was first dicovered in the from of penicillin as they come from the fungi penicillum.
Toxin
That depends on what substance you are talking about.
The jelly like substance is agar and is produced from seaweed. In the laboratory, the agar is placed in a Petri Dish.
You want to talk about antibiotics. By definition it is the substance produced by microorganisms to inhibit the growth of other microorganisms. Most of such chemicals are produced by fungi. Only few like bacitracin are produced by bacteria.

Some bacteria, most notably species in the genus Streptomyces and Actinomycetes produce antibiotics as secondary metabolites. Aside from bacteria, some fungi such as Penicillium produce antibiotics as well. Scientists were then able to purify the antibiotics produced from the microbes for clinical purposes.

It could be either or both, depending on the microbe.
Toxin
The answer depends upon which type of microbe is being looked at, but, since they are microscopic and color is produced by reflection of different frequencies of light, almost all appear to be transparent, especially the single celled microbes and those without membranes or nuclei. For purposes of study under a microscope stains are applied to the microbes so that they can be seen and when looking at microscopic pictures of bacteria and other microbes, the bright colors are produced by these stains. Exceptions to this are the microscopic plants like green algae. Since they have chlorophyll for photosynthesis, they will have some natural green coloration.
