Weibull Claes (Central Bacteriological Laboratory of Stockholm City, Stockholm, Sweden), and Hans Gyllang. Metabolic properties of some L forms derived from gram-positive and gram-negative bacteria. J. Bacteriol. 89:1443-1447. 1965.-L forms of two gram-positive bacteria, a staphylococcus and a diphtheroid, were found to be devoid of catalase and cytochromes, whereas the normal bacteria from whi...

A 81-kDa protein from Mycobacterium sp. strain PYR-1 was expressed in response to exposure of the strain to the polycyclic aromatic hydrocarbon pyrene and recovered by two-dimensional gel electrophoresis. The N-terminal sequence of the protein indicated that it was similar to catalase-peroxidase. An oligonucleotide probe designed from this sequence was used to screen a genomic library of Mycoba...

The thermophilic streptococci are dominant members of the microflora of several types of cheese produced with a natural starter. A total of 205 isolates of thermophilic streptococci were obtained from 70 samples of white cheese which had been collected from producing areas of different regions of Syria during 2009 and 2010. The isolates were cocci gram positive and catalase negative. From these...

A dwarf strain of Staphylococcus aureus was isolated in pure culture from styes on the eyelid of a young woman. Incubation of pus cultured on horse blood agar in 5% CO2 yielded a typical golden staphylococcus, coagulase and catalase positive and penicillin sensitive, but on duplicate plates in air the growth was of tiny white colonies only 0.25 mm. in diameter. These were penicillinsensitive Gr...

Three novel strains were isolated from a soil sample collected in Japan using GPM agar plates supplemented with superoxide dismutase and/or catalase. The strains were Gram-positive, catalase-positive, irregular rod-shaped bacteria with meso-diaminopimelic acid as a peptidoglycan diagnostic diamino acid, and the acyl type of the peptidoglycan was acetyl. The major menaquinone was MK-8(H4). Mycol...

Different tests for the identification of Gardnerella (Haemophilus) vaginalis and for its differentiation from catalase-negative unclassified coryneforms from the vagina were evaluated on over 200 bacterial strains, with special emphasis on optimal test conditions. A presumptive identification of G. vaginalis in the clinical laboratory can be made on the basis of colonial morphology, clear beta...

Two strains of an unknown Gram-positive, catalase-negative, facultatively anaerobic coccus originating from the reproductive tract of horses were characterized by phenotypic and molecular taxonomic methods. Comparative 16S rRNA gene sequencing studies demonstrated that the two strains constitute a new subline within the lactic-acid group of bacteria, close to, but distinct from, Abiotrophia def...

Flammulina velutipes was treated with 10, 50, and 250 μL L−1 isoamyl isothiocyanate (IAITC), effects on quality preservation were assessed. IAITC displayed positive during the storage of F. velutipes: (i) maintained tissue integrity, reduced weight loss rates; (ii) browning degree by inhibiting activities browning-related enzymes; (iii) enhanced two antioxidant enzymes (superoxide dismutase cat...
