As Gram positive bacteria lack an outer lipid membrane, when correctly referring to their structure rather than staining properties, are termed monoderms. The outer lipid membrane possessed by Gram ...

The Gram staining is a standard staining method that has been used to distinguish bacteria for a long time, however, there have been many difficulties with this method, requiring multi-steps of ...

Bacterial Staining Techniques III Recently we have done two differential stains, the Gram stain and the Acid Fast stain. Both stains differentiate between bacteria chemically. The two staining ...

The Gram stain is almost always the first step in the preliminary identification of a bacterial organism. Gram was then appointed a professor of medicine at the University of Copenhagen in 1900.

Published by Hans Christian Gram in 1884, gram staining distinguishes gram-positive bacteria (purple) from gram-negative bacteria (pink). Gram-positive critters, such as staph, have a thick ...

Gram-positive bacteria are bacteria that contain a thick cell wall. During the Gram staining process — a test that experts use to view the bacteria under a microscope — they appear purple or blue.
