In microbiology, collective bacteria and other microorganisms in a host are historically known as flora. Although microflora is commonly used, the term microbiota is becoming more common as microflora is a misnomer. Flora pertains to the Kingdom Plantae. Microbiota includes Archaea, Bacteria, Fungi and Protists. Microbiota with animal-like characteristics can be classified as microfauna.
The terms "Flora" and "Fauna" were first used by Carl Linnaeus from Sweden in the title of his 1745[1] work Flora Suecica and Fauna Suecica. At that time, biology was focused on macroorganisms. Later, with the advent of microscopy, the new discovered ubiquitous microorganisms were fit in this system. Then, Fauna included moving organisms (animals and protist as "micro-fauna") and Flora the organisms with apparent no movement (plants/fungi; and bacteria as "microflora"). The terms "microfauna" and "microflora" are common in old books, but recently they have been replaced by the more adequate term "microbiota".[2] Microbiota includes Archaea, Bacteria, Fungi and Protists.
Microflora are grouped into two categories based on the origin of the microorganism.[3]
Microflora is a term that refers to a community of bacteria that exist on or inside the body, and possess a unique ecological relationship with the host.[4] This relationship encompasses a wide variety of microorganisms and the interactions between microbes. These interactions are often a mutualistic relationships between the host and autochthonous flora. Microflora responsible for harmful diseases are often allochthonous flora.
The modern term is "Microbiome" and include microorganisms that have different roles in ecosystems or hosts, including free-living organisms, or organisms associated to hosts, such animals (including humans) or plants.[5]
In 2008, the National Institutes of Health started the Human Microbiome Project designed to help understand the health implications of human bacterial flora.[6] Biologists believe that bacterial flora may play some role in disorders such as multiple sclerosis. Additionally, the study of flora can have industrial benefits such as dietary supplements like probiotics. The living microorganisms in probiotics are believed to have positive effects on health, and have been utilized in studies regarding gastrointestinal diseases and allergies.
In 2014, the Earth Microbiome project proposed a broad initiative to identify the diversity and importance of the microbiota in different ecosystems across the planet, including free-living microbiota (in water and terrestrial systems) and host associated-microbiota (associated with plants and animals).[7]

Nocardia is a genus of weakly staining Gram-positive, catalase-positive, rod-shaped bacteria. Species from this genus form partially acid-fast beaded branching filaments (appearing similar to fungi, but being truly bacteria). It contains a total of 85 species. Some species are nonpathogenic, while others are responsible for nocardiosis. Nocardia species are found worldwide in soil rich in organic matter. In addition, they are oral microflora found in healthy human gingiva, as well as periodontal pockets. Most Nocardia infections are acquired by inhalation of the bacteria or through traumatic introduction through openings in epithelial barriers.

A lawn aerator is a garden tool designed to create holes in the soil in order to help lawn grasses grow. In compacted lawns, aeration improves soil drainage and encourages worms, microfauna and microflora which require oxygen.
A fermentation starter (called simply starter within the corresponding context, sometimes called a mother) is a preparation to assist the beginning of the fermentation process in preparation of various foods and alcoholic drinks. Food groups where they are used include breads, especially sourdough bread, and cheese. A starter culture is a microbiological culture which actually performs fermentation. These starters usually consist of a cultivation medium, such as grains, seeds, or nutrient liquids that have been well colonized by the microorganisms used for the fermentation. These starters are formed using a specific cultivation medium and a specific mix of fungal and bacterial strains. Typical microorganisms used in starters include various bacteria and fungi (yeasts and molds): Rhizopus, Aspergillus, Mucor, Amylomyces, Endomycopsis, Saccharomyces, Hansenula anomala, Lactobacillus, Acetobacter, etc. Various national cultures have various active ingredients in starters, and often involve mixed microflora. Industrial starters include various enzymes, in addition to microflora.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
