The objectives of these studies were to determine cell yield and fermentation responses of a Salmonella enterica serovar Typhimurium poultry isolate using various dilution rates in steady state continuous culture incubations. S. enterica Typhimurium cells were propagated in continuous cultures with a total volume of 0.50 l of Luria Bertani medium containing 0.1% glucose. Dilution rates from 0.0125 to 1.44/h were used. Cell protein concentration generally increased linearly with increased dilution rate up to a rate of 0.54/h and declined at the higher dilution rates. Glucose consumption gave a similar pattern to cell protein concentration by declining at the three highest dilution rates. Short chain fatty acid production was inconsistently influenced by dilution rate. Acetate, the most predominant fatty acid produced, declined at the higher dilution rates, as did propionate. Ammonia production remained stable at the lowest dilution rates, but increased significantly at a dilution rates above 0.27/h.

The objective of this study was to determine whether fermentation by a cecal probiotic co-culture of an Enterococcus sp. and Veillonella sp. would inhibit the in vitro growth of a S. typhimurium poultry isolate. The growth rates of S. typhimurium and Enterococcus were significantly reduced at pH 5. At the two pH levels, there was a significant (p < 0.001) increase at 24 h in colony forming units for each of the bacteria enumerated from the mixed culture compared to the respective pure culture enumerations. S. typhimurium was not inhibited in mixed cultures. The mixed cultures produced more acetate than any of the pure cultures and lactate produced by Enterococcus appeared to be utilized by Veillonella.

“…Correlation studies have indicated that volatile fatty acids, particularly propionic acid, might be important in the reduction of Salmonella viable counts (19,32). However, it is not known whether the relationship between volatile fatty acids and reduction in numbers of salmonellae is causal or coincidental.…”

Competitive exclusion of Salmonella enterica serovar Enteritidis by a mixed culture of Lactobacillus crispatus and Clostridium lactatifermentans was studied in a sequencing fed-batch reactor mimicking the cecal ecophysiology of broiler chickens. Growth of serovar Enteritidis was inhibited by a mixed culture of L. crispatus and C. lactatifermentans at pH 5.8 but not by a monoculture of L. crispatus at the same pH. Moreover, experiments performed at pH 7.0 did not show growth inhibition of serovar Enteritidis. L. crispatus fermented lactose to lactate, and C. lactatifermentans fermented the lactate to acetate and propionate in a mixed culture of L. crispatus and C. lactatifermentans growing on lactose. In contrast, only lactate was produced from lactose by a monoculture of L. crispatus. At pH 5.8 considerable concentrations of acetate and propionate were present as undissociated acids, whereas only trace levels of undissociated lactate were present at pH 5.8 due to the low pK a of lactate. At pH 7.0 all three acids were present in their dissociated forms. We conclude that a mixed culture of L. crispatus and C. lactatifermentans inhibits growth of serovar Enteritidis under cecal growth conditions. The undissociated forms of acetate and propionate produced in the mixed culture inhibited the growth of serovar Enteritidis.
