Bacteroides Plebeius
''Phocaeicola plebeius'', formerly ''Bacteroides plebeius'', is a microbe found in the Human digestive system, human gut, most commonly in Japanese people, Japan natives. It is able to digest porphyran, a polysacchide from ''Porphyra'' seaweed (nori) that humans cannot digest on their own. The porphyranase-encoding gene Bp1689 is believed to have been derived from the microbe ''Zobellia galactanivorans'' via horizontal gene transfer, as part of a gene cluster containing other CAZy, carbohydrate-active enzymes. Composition of red algae ''Porphyra'' ''Porphyra'' is a genus of red seaweed. The two main ''Porphyra'' used in Japanese dishes are ''Porphyra yezoensis, P. yezoensis'' and ''Porphyra tenera, P. tenera'' which are commonly used in sushi. ''Porphyra spp.'' also known as nori in Japan contains compounds such porphyrans and agaroses that are indigestible to people lacking ''P. plebius''. Rhodophyta, the phylum of red algae, has a cell wall composed of sulfated galactans. Agar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microbe
A microorganism, or microbe, is an organism of microscopic size, which may exist in its single-celled form or as a colony of cells. The possible existence of unseen microbial life was suspected from antiquity, with an early attestation in Jain literature authored in 6th-century BC India. The scientific study of microorganisms began with their observation under the microscope in the 1670s by Anton van Leeuwenhoek. In the 1850s, Louis Pasteur found that microorganisms caused food spoilage, debunking the theory of spontaneous generation. In the 1880s, Robert Koch discovered that microorganisms caused the diseases tuberculosis, cholera, diphtheria, and anthrax. Microorganisms are extremely diverse, representing most unicellular organisms in all three domains of life: two of the three domains, Archaea and Bacteria, only contain microorganisms. The third domain, Eukaryota, includes all multicellular organisms as well as many unicellular protists and protozoans that are ...
