Oxygen metabolism of catalase-negative and catalase-positive strains of Lactobacillus plantarum.

Two catalase-negative strains of Lactobacillus plantarum and a strain producing the atypical, nonheme catalase were studied to determine if the ability to produce the atypical catalase conferred any growth advantage upon the producing strain. Both catalase-negative strains grew more rapidly than the catalase-positive strain under aerobic or anaerobic conditions in a glucose-containing, complex ...

Hydrogenase activity in catalase-positive strains of Campylobacter spp.

A rapid hydrogenase assay has been developed which may be useful in separating the species Campylobacter jejuni and C. coli from the subspecies C. fetus subsp. fetus and C. fetus subsp. venerealis. This assay employs the impermeant redox dye benzyl viologen, and positive determinations can be made within 20 min. All strains of C. jejuni and C. coli were found to be strongly hydrogenase positive...

Cloning and heterologous expression of hematin-dependent catalase produced by Lactobacillus plantarum CNRZ 1228.

Lactobacillus plantarum CNRZ 1228 exhibited heme-dependent catalase activity under environmental conditions similar to those encountered during sausage fermentation. The 1,455-bp catalase gene (katL) was cloned and encoded a protein of 484 amino acids. Expression of katL in a heterologous host showed that katL encodes a functional catalase. PCR screening of selected strains of lactic acid bacte...

Catalase-producing strains of streptococci.

The genus Streptococcus includes organisms which are homofermentative, facultative with respect to oxygen, fastidious in their nutrient requirements, without cytochrome system, and are therefore considered to be catalase negative. Recent work in this laboratory revealed two strains of several hundred streptococci, screened from silage fermentations, that were capable of producing catalase. They...

Multiple Genome Sequences of Lactobacillus plantarum Strains

We report here the genome sequences of four Lactobacillus plantarum strains which vary in surface hydrophobicity. Bioinformatic analysis, using additional genomes of Lactobacillus plantarum strains, revealed a possible correlation between the cell wall teichoic acid-type and cell surface hydrophobicity and provide the basis for consecutive analyses.
