Within a number of classes of hydrolytic enzymes are certain enzymes whose activity is modulated by a specific inhibitor-protein that binds to the enzyme and forms an inactive complex. One unit of a specific inhibitor-protein activity is often defined as the amount necessary to inhibit one unit of its target enzyme by 50 %. No objective quantitative means is available to determine this point of...
In this paper it is shown that if the dry seeds of the cantaloupe (Cucumis melo) are soaked for 3 hours in solutions of ethyl alcohol of concentration ranging from 2 to 16 per cent by volume, and then germinated and grown in distilled water in the dark, the total growth attained is greater by amounts ranging from 9 to 35 per cent than is that made by seeds treated in every way identically excep...
U.S. salmonellosis outbreaks have occurred following consumption of tomato and cantaloupe but not lettuce. We report differential contamination among agricultural seedlings by Salmonella enterica via soil. Members of the family Brassicaceae had a higher incidence of outbreak than carrot, lettuce, and tomato. Once they were contaminated, phyllosphere populations were similar, except for tomato. ...
In studying the relationship between ethylene production and the climacteric rise in respiration exhibited by ripening fruits, it was not possible to determine when ethylene production begins until the advent of gas chromatography. This technique makes available quantitative measurement of ethylene concentrations at or below the threshold of physiological activity. Burg and Thimann (3, 4) were ...
Using an automated rapid headspace solid phase microextraction (SPME) method for volatile extraction in cantaloupes, 86 compounds already reported for muskmelons were recovered and an additional 53 compounds not previously reported were identified or tentatively identified. The SPME method extracted a copious number of volatiles that can be analyzed to clearly differentiate between variety, gro...
For example, a case-control study of sporadic infections enabled an unprecedented response time during the large U.S. listeriosis outbreak in 2011. Data collected by the Listeria Initiative led to the identification of an association with cantaloupe within days rather than weeks or months (CDC, 2011a). We estimate that the commercial recall of the implicated cantaloupe just 12 days from outbrea...
