This study reports the prevalence of sporeforming bacteria and contamination levels a variety powdered dairy products from cows', ewes', goats' mares’ milk produced in France. The concentration mesophilic spores, thermophilic spores highly heat-resistant was assessed 61 powders. Thermophilic spore variable between powders, likely due to different manufacturing processes used for transforming in...

Sporeformers isolated from a commercially canned food were identified as Bacillus cereus, lactose-positive variants. The thermal resistance of spore crops produced from each of two representative cultures was determined in 0.067 M phosphate buffer at pH 7.0. The D121.1 values for one isolate were approximately 0.03 min (z = 9.9C), whereas the D121.1 values for the other isolate were 2.35 min (z...

Lactobacilli have been crucial for the production of fermented products for centuries. They are also members of the mutualistic microbiota present in the human gastrointestinal and urogenital tract. Recently, increasing attention has been given to their probiotic, health-promoting capacities. Many human intervention studies demonstrating health effects have been published. However, as not all s...

In order to provide health benefits potential probiotic strains must be viable and metabolically active in the product and maintance their activity in gastrointestinal tract (GIT). Therefore, the current investigations are based on protection of probiotics by microencapsulation to increase survival and delivery of bacterial cultures to the GIT. Several reports have shown better survival of enca...

Psychrotolerant sporeformers pose a challenge to maintaining fluid milk quality. Dynamic temperature changes along the supply chain can favor germination and growth of these bacteria lead spoilage. In this study, we aim expand on our previous work predicting spoilage due psychrotolerant sporeformers. The key model innovations include (i) ability account for changing temperatures chain, (ii) dep...

Oral consumption of probiotic bacteria has the potential to support the health of American consumers. This paper will discuss the rationale of the probiotic theory, several health targets for probiotic bacteria, probiotic products in the U.S. and, finally, issues pertaining to communication about probiotic products to the consumer.

Sporeformers isolated from a commercially canned food were identified as Bacillus cereus, lactose-positive variants. The thermal resistance of spore crops produced from each of two representative cultures was determined in 0.067 M phosphate buffer at pH 7.0. The D12,A, values for one isolate were approximately 0.03 min (z = 9.9 C), whereas the D121.1 values for the other isolate were 2.35 min (...

The use of defined probiotic cultures in the poultry industry has recently become more common. However, few conclusive studies regarding their efficacy under commercial conditions have been reported in the scientific literature. We conducted a study that included 118 commercial turkey hen lots, ranging from 1,542 to 30,390 hens per lot, of either Nicholas or Hybrid genetic lines, to look at the...
