Aerococcus is a genus in the phylum Bacillota (). [1] The genus was first identified in 1953 from samples of air and dust as a catalase-negative, gram-positive coccus that grew in small clusters. [2]
The name Aeriscardovia derives from: Latin masculine gender noun aer aeris, air; Neo-Latin feminine gender noun Scardovia, a bacterial generic name to honor Vittorio Scardovi, an Italian microbiologist; Neo-Latin feminine gender noun Aeriscardovia, cells similar to the genus Scardovia that can grow in air.
Lactobacillus is a genus of gram-positive, aerotolerant anaerobes or microaerophilic, rod-shaped, non-spore-forming bacteria. [2] [3] Until 2020, the genus Lactobacillus comprised over 260 phylogenetically, ecologically, and metabolically diverse species; a taxonomic revision of the genus assigned lactobacilli to 25 genera (see § Taxonomy below).
Microbiology (from Ancient Greek μῑκρος (mīkros) 'small' βίος (bíos) 'life' and -λογία () 'study of') is the scientific study of microorganisms, those being of unicellular (single-celled), multicellular (consisting of complex cells), or acellular (lacking cells).
Clostridium is an example. Sulphate-reducing bacteria are important in ocean sediments (e.g. Desulfovibrio), and some Archean methanogens, like Methanococcus, fix nitrogen in muds, animal intestines [3] and anoxic soils. [4] Facultative anaerobes—these species can grow either with or without oxygen, but they only fix nitrogen anaerobically.
Numerous taxa from both soil and freshwater systems have been captured from the air (e.g., bacteria, several algae, ciliates, flagellates, rotifers, crustaceans, mites, and tardigrades). [ 74 ] [ 75 ] [ 174 ] [ 175 ] While these have been qualitatively well studied, accurate estimates of their dispersal rates are lacking.
Bacillus (Latin "stick") is a genus of Gram-positive, rod-shaped bacteria, a member of the phylum Bacillota, with 266 named species.The term is also used to describe the shape (rod) of other so-shaped bacteria; and the plural Bacilli is the name of the class of bacteria to which this genus belongs.
