Microflora is the collective term for all the microorganisms inhabiting a particular environment, from the bacteria, yeasts, and molds on a food surface to the microbial communities of soil, water, or the human gut. In a broader biological sense it can also include microscopic plants and algae of a microhabitat. In food science, understanding a product’s microflora is central to predicting spoilage, designing fermentations, and assessing safety: the balance between desirable fermenters, harmless background organisms, and pathogens determines shelf life and risk. Analysts profile microflora with culturing, microscopy, and DNA-based methods such as sequencing, which reveal the full community rather than only what grows on plates.
