microflora

This term refers to a collective biological community, functioning as a mass noun. It describes the totality of microscopic organisms in a specific niche rather than individual microbes. In scientific discourse, it is used to emphasize the ecosystem as a single functional unit.

Because it is an uncountable noun, it does not have a plural form. To refer to multiple distinct types of microbial communities or different environments, speakers typically use phrases such as "types of microflora" or "various microflora populations."
