The aminopeptidase test was performed with representatives of gram-negative, gram-positive, and gram-variable bacteria. All gram-negative bacteria tested gave a positive test reaction with L-alanine-4-nitroanilide as test substrate. Representatives of the coryneform bacteria and some streptococci sh

β¦ Synopsis
A rapid method for distinction between gram-negative and grampositive bacteria by means of a 3% solution of potassium hydroxide is tested on 71 gram-positive and 55 gram-negative bacterial strains. The method proved reliable with one exception only, a Bacillus macerans strain. That strain was definately gram-negative on staining. Other Bacillus strains were proved grampositive by the test, even those being gram-negative on staining.

## Abstract A series of statistical copolymers derived from 2β(dimethylamino)ethyl methacrylate with four different hydrophobic comonomers (ethyl, butyl, cyclohexyl, and octyl methacrylates) have been prepared via conventional free radical copolymerization under bulk conditions. The copolymers have
Previous studies on the photosensitization of bacterial cells with different neutral or negatively charged porphyrins and phthalocyanines have demonstrated that, although Gram-positive bacteria are efficiently photoinactivated, Gram-negative bacteria become photosensitive only after modification of
Different bacteria, isolated from soil by the enrichment method, were able to grow on phthalic acid as carbon source. Protocatechuate was identified as intermediate in phthalate metabolism. All phthalategrown bacteria oxidized phthalate and protocatechuate rapidly without having a lag-period. Benzoi
