Heat-induced requirements for sucrose or magnesium for expression of heat resistance in Bacillus cereus forespores.

Busta, F F, Baillie, E, Murrell, W G

The addition of 0.6 M sucrose of 0.016 M Mg2+ to the enumeration medium was required for early expression of heat resistance (10 min at 70 degrees C) in stage V Bacillus cereus forspores. The...

Scanning electron probe x-ray microanalysis of elemental distributions in freeze-dried cryosections of Bacillus coagulans spores.

Stewart, M, Somlyo, A P, Somlyo, A V, Shuman, H, Lindsay, J A, Murrell, W G

High-resolution scanning electron probe X-ray microanalysis had been employed to examine elemental distributions in freeze-dried cryosections of Bacillus coagulans spores. Calcium, manganese, and...

Initiation of Bacillus spore germination by hydrostatic pressure: effect of temperature.

Murrell, W G, Wills, P A

Suspensions of Bacillus cereus T, B. subtilis, and B. pumilus spores in water or potassium phosphate buffer were germinated by hydrostatic pressures of between 325 and 975 atm. Kinetics of...

Exosporium and Spore Coat Formation in Bacillus cereus T

Ohye, D. F., Murrell, W. G.

The exosporium of Bacillus cereus T was first observed as a small lamella in the cytoplasm in proximity to the outer forespore membrane (OFSM) near the middle of the sporangium. Serial sections,...

Use of Ultraviolet Radiation to Locate Dipicolinic Acid in Bacillus cereus Spores

Germaine, G. R., Murrell, W. G.

A novel method is described that allows a direct determination of the location of a portion of the dipicolinic acid (DPA) in spores. Ultraviolet (UV) irradiation is shown to cause cross-linkage of...

GERMINATION PROPERTIES OF SPORES WITH LOW DIPICOLINIC ACID CONTENT

Keynan, A., Murrell, W. G., Halvorson, H. O.

Keynan, A. (University of Wisconsin, Madison), W. G. Murrell, and H. O. Halvorson. Germination properties of spores with low dipicolinic acid content. J. Bacteriol. 83:395–399. 1962.—When the...

Development of Ultraviolet Resistance in Sporulating Bacillus cereus T

Germaine, G. R., Coggiola, Elizabeth, Murrell, W. G.

Ultraviolet (UV) resistance patterns of sporulating Bacillus cereus were determined. Six different categories of UV resistance were discernible as the organism progressed from exponential growth to...

Rapid radiometric method for detection of Salmonella in foods.

Stewart, B J, Eyles, M J, Murrell, W G

A radiometric method for the detection of Salmonella in foods has been developed which is based on Salmonella poly H agglutinating serum preventing Salmonella from producing 14CO2 from [14C]dulcitol....

Distribution of calcium and other elements in cryosectioned Bacillus cereus T spores, determined by high-resolution scanning electron probe x-ray microanalysis.

Stewart, M, Somlyo, A P, Somlyo, A V, Shuman, H, Lindsay, J A, Murrell, W G

The distribution of a number of key elements in Bacillus cereus T spores was determined by high-resolution scanning electron probe X-ray microanalysis. To circumvent the redistribution of soluble or...

FORMATION AND STRUCTURE OF THE SPORE OF BACILLUS COAGULANS

Ohye, D. F., Murrell, W. G.

Spore formation in Bacillus coagulans has been studied by electron microscopy using an epoxy resin (Araldite) embedding technique. The developmental stages from the origin of the initial spore septum...

THE COMPOSITION AND STRUCTURE OF BACTERIAL SPORES

Warth, A. D., Ohye, D. F., Murrell, W. G.

The composition of the insoluble "integuments" and soluble "contents" fractions of spores of four Bacillus species of widely differing heat resistance were compared. Electron microscopy of thin...

LOCATION AND COMPOSITION OF SPORE MUCOPEPTIDE IN BACILLUS SPECIES

Warth, A. D., Ohye, D. F., Murrell, W. G.

Spore integuments of Bacillus coagulans were prepared containing nearly all the hexosamine and α, ε-diaminopimelic acid (DAP) present in intact spores. Subsequent autolytic action resulted in the...
