Using the Pritchard photometer as a specific example, this paper introduces a radial weighting function to describe both the in-focus and out-of-focus operation of a photometer. In both cases the central region in the instrument field of view contrib

The objectives of the present report were to examine the ability of 18 strains of Escherichia coli O157:H7 to grow in EC broth at 42.4, 43.5, 44.5, and 45.5 degrees C, and to document the incidence of phenotypic variants present in low numbers that a

A new lysis solution designated TZ, consisting of 2.0% Triton X-100 plus 2.5 mg sodium azide/ml in 0.1 M Tris-HCl buffer at pH 8.0, yielded higher levels of genomic DNA from Escherichia coli O157:H7 cells compared with a number of other commonly used

A direct spectrophotometric immuno-agglutination assay for quantitation of specific Escherichia coli O157 IgG was developed. Initial linear rates of increase in absorbance at 550 nm as a result of agglutination were found to increase with both cell a

Fish waste or gurry comprises up to 60% of the original weight of fish after fillets are removed. The entrails of certain fish species such as haddock, cod and flounder are usually removed and discarded at sea so that the gurry comprises of heads, ta

Caffeine alone induced the SOS functions recA and umuC in wild type recA-lacZ and umuC-lacZ fusion systems in Escherichia coli strains. Caffeine was also able to induce umuC in a umuC-lacZ fusion strain defective in excision repair. Caffeine however

Several additives were examined for their effect on the growth of microorganisms in ground beef. NaCl inhibited growth at 3% and 1.5% by weight, while none of the ofher additives tested, either alone or in combination, affected the growth of microorg
