Publikováno v: Applied and Environmental Microbiology. 57:539-548

Evidence is presented that lactose-fermenting ability (Lac+) in Lactococcus lactis subsp. cremoris AM1, SK11, and ML1 is associated with plasmid DNA, even though these strains are difficult to cure of Lac plasmids. When the Lac plasmids from these st

Molecular analyses of the lactococcin A gene cluster from Lactococcus lactis subsp. lactis biovar diacetylactis WM4

Autor: G W Stoddard, M J van Belkum, Jan Kok, J P Petzel, Larry L. McKay

The genes responsible for bacteriocin production and immunity in Lactococcus lactis subsp. lactis biovar diacetylactis WM4 were localized and characterized by DNA restriction fragment deletion, subcloning, and nucleotide sequence analysis. The nucleo

Molecular characterization of the integration of the lactose plasmid from Lactococcus lactis subsp. cremoris SK11 into the chromosome of L. lactis subsp. lactis

Autor: Larry L. McKay, J P Petzel

When Lactococcus lactis subsp. lactis LM0230 is transformed by the lactose plasmid (pSK11L) from Lactococcus lactis subsp. cremoris SK11, variants with pSK11L in the integrated state can be derived (J. M. Feirtag, J. P. Petzel, E. Pasalodos, K. A. Ba

Publikováno v: International Journal of Systematic Bacteriology. 38:417-423

We studied the purine enzyme activities in dialyzed cytoplasmic extracts from the following eight species, representing four genera, of Mollicutes: Mycoplasma pneumoniae FHT (T = type strain) and M129, Mycoplasma bovigenitalium PG-11T, Mycoplasma hom

Enzymic activities of carbohydrate, purine, and pyrimidine metabolism in the Anaeroplasmataceae (class Mollicutes)

Autor: M V Williams, John T. Manolukas, Paul A. Hartman, Pollack Jd, M. C. McELWAIN, J. P. Petzel, D. Desantis, Milton J. Allison

Publikováno v: Archives of Microbiology. 152:309-316

Cell-free extracts of two strictly anaerobic mollicutes, Anaeroplasma intermedium 5LA and Asteroleplasma anaerobium 161T, were tested for enzymic activities of intracellular carbohydrate metabolism. Asteroleplasma anaerobium was also tested for enzym

A phylogenetic analysis of the mycoplasmas: basis for their classification

Autor: T G Lawrence, J G Tully, J P Petzel, H Oyaizu, Linda Mandelco, J Van Etten, J E Sechrest, William G. Weisburg, D Yang, D L Rose

Publikováno v: Journal of Bacteriology. 171:6455-6467

Small-subunit rRNA sequences were determined for almost 50 species of mycoplasmas and their walled relatives, providing the basis for a phylogenetic systematic analysis of these organisms. Five groups of mycoplasmas per se were recognized (provisiona

Monensin-based medium for determination of total gram-negative bacteria and Escherichia coli

Autor: J P Petzel, P A Hartman

Publikováno v: Applied and Environmental Microbiology. 49:925-933

Plate count-monensin-KCl (PMK) agar, for enumeration of both gram-negative bacteria and Escherichia coli, is composed of (per liter) 23.5 g of plate count agar, 35 mg of monensin, 7.5 g of KCl, and 75 mg of 4-methylumbelliferyl-beta-D-glucuronide (MU

A note on starch hydrolysis and beta-glucuronidase activity among flavobacteria

Autor: J. P. Petzel, P. A. Hartman

Publikováno v: The Journal of applied bacteriology. 61(5)

Most flavobacteria tested with the fluorogenic substrate 4-methylumbelliferyl-beta-D-glucuronide possessed beta-glucuronidase (GUD), but when some of the same strains were tested with the API ZYM gallery, all were negative for GUD. Conflicting report
