  2. Nanobacterium - Wikipedia

    en.wikipedia.org/wiki/Nanobacterium

    Structures found on meteorite fragment Allan Hills 84001. Nanobacterium (/ ˌ n æ n oʊ b æ k ˈ t ɪər i əm / NAN-oh-bak-TEER-ee-əm, pl. nanobacteria / ˌ n æ n oʊ b æ k ˈ t ɪər i ə / NAN-oh-bak-TEER-ee-ə) is the unit or member name of a former proposed class of living organisms, specifically cell-walled microorganisms, now discredited, with a size much smaller than the generally ...

  3. Ultramicrobacteria - Wikipedia

    en.wikipedia.org/wiki/Ultramicrobacteria

    These bacteria were found in groundwater samples and analyzed with 2-D and 3-D cryogenic transmission electron microscopy. These ultra-small bacteria, about 1 million base pairs long, [ 6 ] display dense spirals of DNA, few ribosomes, hair-like fibrous appendages, and minimized metabolic systems. [ 6 ]

  4. Catenulida - Wikipedia

    en.wikipedia.org/wiki/Catenulida

    The diet of most catenulids consists of small invertebrates and algae that they capture from the water column. [6] Others, such as those of the genus Paracatenula use chemoautotrophic bacterial symbionts that live inside their cells as a food source.

  5. Food microbiology - Wikipedia

    en.wikipedia.org/wiki/Food_microbiology

    Food microbiology is the study of the microorganisms that inhabit, create, or contaminate food.This includes the study of microorganisms causing food spoilage; pathogens that may cause disease (especially if food is improperly cooked or stored); microbes used to produce fermented foods such as cheese, yogurt, bread, beer, and wine; and microbes with other useful roles, such as producing ...

  6. Planctomycetota - Wikipedia

    en.wikipedia.org/wiki/Planctomycetota

    An additional CSI has been found that is shared by all Planctomycetota species, with the exception of Kuenenia stuttgartiensis. This supports the idea that K. stuttgartiensis forms a deep branch within the Planctomycetota phylum. A CSI has also been found to be shared by the entire PVC superphylum, including the Planctomycetota.

  7. Galactomannan - Wikipedia

    en.wikipedia.org/wiki/Galactomannan

    A segment of galactomannan showing mannose backbone (below) with a branching galactose unit (top) Galactomannans are polysaccharides consisting of a mannose backbone with galactose side groups, more specifically, a (1-4)-linked beta-D-mannopyranose backbone with branchpoints from their 6-positions linked to alpha-D-galactose, (i.e. 1-6-linked alpha-D-galactopyranose).

  8. Heterocyst - Wikipedia

    en.wikipedia.org/wiki/Heterocyst

    The Azolla plant undergoes photosynthesis and provides fixed carbon for the Anabaena to use as an energy source for dinitrogenases in the heterocyst cells. [8] In return, the heterocysts are able to provide the vegetative cells and the Azolla plant with fixed nitrogen in the form of ammonia which supports growth of both organisms.

  9. Phlorotannin - Wikipedia

    en.wikipedia.org/wiki/Phlorotannin

    Chemical structure of tetrafucol A, a fucol-type phlorotannin found in the brown alga Ascophyllum nodosum Durvillaea antarctica, a brown algae containing phlorotannins. Phlorotannins are a type of tannins found in brown algae such as kelps and rockweeds [ 1 ] or sargassacean species, [ 2 ] and in a lower amount also in some red algae . [ 3 ]
