Rainforest Bacteria
Acidophilic Bacteria
These bacteria grow in highly acidic environments and actually are not just bacteria. They can be grouped with protists and archaebacteria. They usually function well in hot areas and with the rainforest being well, hot of course, there's bound to be some acidophillic bacteria found. Acidophiles can be either unicellular or multicellular, but they are commonly green algae-like formed and usually unicellular. What's actually pretty cool about these tiny organisms is that they are actually used in the process in which you would bio-leach copper and other metals from ore.
Actinomycetes
These are actually some of the largest and most complex types of bacteria. This possibly could be caused by the traces of gram-positive in it. Gram-positive is an extremely dangerous and in most cases deadly to all living things. The strange thing is though, they are found in soil but they do not harm the plants or animals around it! This could be because it's not the same type of actinomycetes. Scientist have discovered a total of about 8 different types of this common bacteria. The most dangerous being the Nocardia Asteroides, which causes tissue infections in humans. This type is not found in this environment of the rainforest.
Mycorrhizae
This fungus also found as a common bacteria plays a MAJOR part in soil life, soil chemistry and the environment in general. It has a mutalistic relationship with the plant, which means it has an association between organisms of two different species in which each member benefits. The fungus has access to the carbohydrates (sugar and glucose) where as the plant benefits from the myceliums high capacity for carrying water and mineral nutrients due to its large surface area. It is actually a proven fact that plants that have mychorrhizal traces are more resistant to diseases, so not only do the plants continue to be pathogen free, but the bacteria gets a home.
