Document Summary

E. g. (cid:373)ilk (cid:272)o(cid:374)tai(cid:374)s sugars i(cid:374) for(cid:373) of (cid:862)gl(cid:455)(cid:272)a(cid:374)s(cid:863). We (cid:272)a(cid:374)(cid:374)ot use these for food u(cid:374)less there are (cid:271)a(cid:272)teria prese(cid:374)t that break down the glycans to usable sugars. E. g. production of vitamin k and vitamin b12. Bacterial naming classified into families on the basis of the relatedness of genetic information (use rrna for typing) Important to know both genus and species names. How do we tell bacteria apart if they are the same shape: simple stains: used just to see if bacteria are present, only one stain is used e. g. methylene blue, differential stains (separate bacteria into different groups): Gram stain: separates bacteria into gram pos or gram neg. Most important practical distinction to know about bacteria is the staining characteristic: gram" tain. Still used as one of the major diagnostic tests used to identify disease causing bacteria. Based on cell wall structure: amount of peptidoglycan in the bacterial cell wall.
