PSEUDOMONAS AUREOFACIENS NOV. SPEC. AND ITS PIGMENTS

Pseudomonas aureofaciens nov. spec. and its pigments.

It is well knowni that the genus Pseudomonas comllpirises several p)igment-producing species, an(l that in all cases in whiich the constitution of these pigments lhais l)een estal)lishedl thlehave leen found to l)e plhenlzine (lerivatives. Wrede and Strack (1929) were the first to prove this foI pyocyanine, the pigment produce(l by Pseudomonas aeruginosa (P. pyocyanea). Pyocvanine is now usuall...

Clostridium sticklandii nov. spec.

Lactobacillus viridescens nov. spec., a heterofermentative species that produces a green discoloration of cured meat pigments.

Niven et al. (1949) described, but did not name, a new species of heterofermentative lactobacillus that frequently is the cause of greening of cured meat pigments. These organisms were found to be physiologically and serologically homogeneous, and have been found widely distributed in and on cured meat products (Niven, 1951). Members of this species have been found to possess some rather unusua...

Taxonomic studies on three marine pleurostomatid ciliates, Litonotus bergeri nov. spec., L. blattereri nov. spec. and L. petzi nov. spec. (Ciliophora, Pleurostomatida) from North China Sea.

The morphology and infraciliature of three pleurostomatid ciliates, Litonotus bergeri nov. spec., L. blattereri nov. spec. and L. petzi nov. spec., collected from mariculture ponds near Qingdao (Tsingtao), China, were investigated using live observations and the protargol impregnation method. These new species are distinguished from their congeners by a combination of characters including the t...
