Cyanobacteria

plural nounˌsʌɪənəʊbakˈtɪərɪəsīˌanō-
Biology
  • 1A division of microorganisms that are related to the bacteria but are capable of photosynthesis. They are prokaryotic and represent the earliest known form of life on the earth.

    〔生〕蓝细菌,藻青菌

    Division Cyanobacteria, kingdom Monera

    Example sentencesExamples
    • They occur only in Cyanobacteria and Rhodophyta.
    • Only Aquificales and Cyanobacteria do not present evidence of such a structuring, possibly because of a sampling effect, since only a few bacteria of these phyla have been presently sequenced.
    • That is, all Cyanobacteria and algal chloroplasts are, together, all of the descendants of some unique common ancestral cyanobacterium.
    • Click on the buttons below to find out more about the Cyanobacteria.
    • The significant buildup probably began about two billion years ago, with the appearance of Cyanobacteria.
    1. 1.1cyanobacteria Microorganisms of the Cyanobacteria division; blue-green algae.
      蓝细菌门微生物;蓝绿藻
      cultures of algae and cyanobacteria
      Example sentencesExamples

Derivatives

  • cyanobacterial

  • adjective
    Biology
    • Light energy is required to power cyanobacterial photosynthesis, however, sediment particles tend to wash onto the surface of the stromatolite, gradually blocking the light and decreasing the light energy available.
      Example sentencesExamples
      • Although providing valuable information on the relationship between structure and function, engineering cyanobacterial and algal Rubiscos has so far failed to produce an enzyme even ‘as good’ as those already found in crop plants.
      • For the cyanobacterial sectors, reactivation occurred only after rain although apparently higher WC maintained NP for longer in these sectors.
      • The reversible mononer - dimer organization of PSII in the photoinhibition repair cycle has been more straightforward to assess in studies of cyanobacterial thylakoid membranes without any lateral heterogeneity.
      • Martin and colleagues have compared 24 990 proteins encoded in the Arabidopsis genome with three cyanobacterial genomes, the yeast genome, and 16 reference genomes from prokaryotes.

Origin

Modern Latin (plural), from Greek kuaneos 'dark blue' + plural of bacterium.
