By far, the most numerous microbes in soil are bacteria, which have just one cell. Also abundant are fungi, which produce long, slender strings of cells called filaments, or hyphae. The actinomycetes are in-between these two organisms. They are advanced bacteria that can form branches like fungi.y far, the most numerous microbes in soil are bacteria, which have just one cell.

Microbial Ecology. 1  Microbial ecology is the study of microbes in the environment and their interactions with each other. 2  Microbes are the tiniest creatures on Earth, yet despite their small size, they have a huge impact on us and on our environment.t is estimated that we know fewer than 1% of the microbial species on Earth. Yet microbes surround us everywhere -- air, water, soil. An average gram of soil contains one billion (1,000,000,000) microbes representing probably several thousand species.
