摘要: SUMMARY: The growth of bacteria in chemically-defined media containing mixtures amino-acids is less dependent upon the magnesium concentration than simple composed saits, glucose or glycerol and a single source nitrogen. In more complex initially increases rapidly with, then becomes independent of, concentration. Gram-positive bacilli jail to grow when content medium 0·66 p.p.m., whereas this amount almost sufficient maintain maximum Gram-negative bacteria. addition, deficiency (i.e. c. 1-5 p.p.m.) inhibits cell division rod-shaped organisms, results formation filamentous cells.
