Effect of a-w of meat products on growth of radiation resistant Moraxella-Acinetobacter
1979
Snyder, L.D. | Maxcy, R.B.
Extract: The growth response of radiation resistant Moraxella-A cinetobacter (M-A) was monitored relative to the a (sub w) of meat and various experimental media. Representative isolates, although obtained from beef, did not grow in ground beef, ground chicken meat, or fresh beef exudate unless the a (sub w) was raised through water addition. Data from a psychrometric thermocouple of the Spanner-Peltier design showed that a (sub w) levels approaching and lower than 0.99 were inhibitory to the growth of M-A. No growth occurred in standard laboratory media when the a (sub w) was lowered to that approximating meat. M-A's inability to grow was not due to an inhibitor in the meat.
