Penicillins and Cephalosporins,ndent to a considerable degree on the background and area of interest of the individual reader. To a classically trained microbiologist, morphological effects may be dominant and of the greatest significance while a biochemically minded individual will wish to know the nature of specific metabolic c整理 发表于 2025-3-25 18:43:38

,-Cycloserine and O-Carbamyl-,-serine,the wall is present as the D-isomer (39–50% in . (I. and S., 1960; T. and S., 1959) and 67% in . (S. .., 1959). S. (1961) has proposed that the occurrence of D-amino acids in the wall renders the bacterium resistant to proteolytic enzymes. Thus, it may be argued that the introduction of D-amino acid朝圣者 发表于 2025-3-26 00:14:17

Pyocyanine,ity of pyocyanine was observed first by E. and Low (1899). They found that old cultures of Ps. . inhibited the growth of a number of Gram-positive and Gram-negative bacteria. Due to the lytic action of culture broths on suspensions of . and ., they ascribed the inhibition to an enzyme termed pyocyanneutrophils 发表于 2025-3-26 15:33:08
Polyene Antibiotics,hat would be equally effective in the treatment of fungal infections. These endeavors have led to the isolation and characterization of numerous antibiotics, which share certain chemical and biological properties, and are now designated as the polyene antibiotics. Although polyene antibiotics have bREP 发表于 2025-3-26 20:44:22

It soon became apparent that all three groups of investigators had discovered closely related substances. At a conference in 1948 which was organized by the New York Academy of Sciences to
