One of the significant class of bacteria has been highlighted in this sqadia.com medical lecture and that encompass the gram-negative bacteria. This follows a debate on aquificae, thermotogae, deinococci, mollicutes along with the photosynthetic bacteria. Moving ahead, phylum chloroflexi, cyanobacteria, phylum planctomycetes, Chlamydiae, spirochaetes, bactroidetes and verrucomicrobia has been delineated.
Aquificae, Thermotogae, Deinococci and Mollicutes
At first, educator talks about gram negative bacteria. After that discusses phylogenetics among bacteria and archaea. Then Aquificae and Thermotogae are explained. This is followed by deinococcus-thermus. Furthermore, class mollicutes (phylum tenericutes) is pursued. Later, mycoplasmas are elaborated. Subsequently, educator explains energy conservation in ureaplasma urealyticum. Lastly, gliding motility in mycoplasmas is elucidated.
Section two is about ''Photosynthetic Bacteria''. Initially, educator introduces photosynthetic bacteria along with oxygenic photosynthesis and anoxygenic photosynthesis. After that photosynthetic pigments are reported. Then comprehensive explanation is given by the educator on characteristics of gram-negative photosynthetic bacteria.
Phylum Chloroflexi and Cyanobacteria
Section three is about ''Phylum Chloroflexi and Cyanobacteria''. Educator begins by discussing phylum chlorobi. Then phylum chloroflexi is explained. Following this, phylum cyanobacteria (blue green algae) is elaborated. Afterwards, cyanobacterial photosynthetic apparatus comes under consideration. Next, carboxysomes are focused. Moreover, characteristics of cyanobacteria are highlighted. Educator also reveals information about cyanobacteria with akinetes and heterocysts. Finally, diversity in cyanobacteria is pursued.
Phylum Planctomycetes and Chlamydiae
Section four is about ''Phylum Planctomycetes and Chlamydiae''. Firstly, phylum planctomycetes is discussed. This phylum is morphologically unique, having compartmentalized cells. After that phylum chlamydiae is elucidated. These are gram-negative obligate intracellular parasites. Subsequently, chlamydial life cycle is exhibited.
Phylum Spirochaetes, Bacteroidetes and Verrucomicrobia
Section five is about ''Phylum Spirochaetes, Bacteroidetes and Verrucomicrobia''. Earlier in this section, phylum spirochaetes come under consideration. Alongside, spirochete morphology is discussed. Then spirochete motility is focused. Likewise, characteristics of spirochetes are reported. Furthermore, pathogenic spirochaetes are explained. Following this, phylum bacteroidetes is elaborated. Bacteroidetes motility is also discussed. Concluding comments are given on phylum verrucomicrobia.
