This study examined the effects of a commercial Lactobacillus probiotic on growth, survival and resistance of western white shrimp (Litopenaeus vannamei) larvae against salinity and formalin stresses in Persian gulf and Oman sea ecology research center. In this experiment, larvae were fed on 6 times a day from mysis I (M1) step to post larvae 5 over 3 treatments with 3 repetitions including a c...

this experiment was conducted to evaluate the effects of different levels of crude protein and probiotic in diets on performance, egg quality  and blood biochemical and immunity parameters of laying hens. a completely randomized design with factorial method (2×4) was conducted in which two levels of crude protein (nrc and 10% lower than nrc recommendation) and 4 levels of probiotic (0, .025%, 0...

Depending on intended use of a probiotic (drug vs. dietary supplement), regulatory requirements differ greatly. For dietary supplements, premarketing demonstration of safety and efficacy and approval by the Food and Drug Administration are not required; only premarket notification is required. Saccharomyces boulardii is a probiotic regulated as a dietary supplement intended for use by the gener...

In the present study, an attempt has been made to assess the probiotic characteristics of lactobacilli and yeast strains isolated from whey beverage under conditions simulating the in vivo stresses encountered in the gastrointestinal tract i.e. acid, alkaline, proteolytic enzymes and bile stress. The therapeutic potential of probiotics Lactobacillus casei or Lactobacillus yoghurt was assessed i...

BACKGROUND The yeast Saccharomyces boulardii is used worldwide as a probiotic to alleviate the effects of several gastrointestinal diseases and control antibiotics-associated diarrhea. While many studies report the probiotic effects of S. boulardii, no genome information for this yeast is currently available in the public domain. RESULTS We report the 11.4 Mbp draft genome of this probiotic y...

Probiotics have been extensively researched for their beneficial health promoting effects. Previously, the mainstream of research was limited to the gastrointestinal flora, but in the past few years it has been more focused towards the oral and dental health perspectives. Few randomized controlled trials have been conducted in this area, though the investigations on probiotics versus oral and d...

The effectiveness of a probiotic formulation applied in human vagina depends on the possibility of adaptation of the beneficial microorganisms in this environment. The understanding of the interactions of potentially probiotic microorganisms with the vaginal fluid, which shows some specific physical and chemical properties, can help to the design of improved vaginal probiotic formulations. The ...

Microencapsulation as one of the most modern methods has considerable effects on probiotic survival. In this study Lactobacillus casei (ATCC 39392) and Bifidobacterium bifidum (ATCC 29521) were encapsulated using calcium alginate-gelatinized starch, chitosan coating and inulin via emulsion technique, and were incubated in simulated gastric juice (along with pepsin, pH=1.5) and simulated intesti...
