conclusions employing the lpe as a new approach, gives novel concept of probiotic-products in food and medical marketing. results results showed that, lpe had more antipathogenic effects, antioxidant activity, and stability during storage-time when compared to fresh probiotic-extract. objectives in this study extract of cultured probiotics without cells was evaluated for its antimicrobial effec...

Studies of the nutritive requirements of the bacterium, Lactobacillus casei, have contributed much to our present knowledge of animal nutrition. It appears that the vitamin requirements of this microorganism are very similar to those of animals. Landy and Dicken (1) reported a microbiological assay method for six B vitamins with Lactobacillus casei and a medium of essentially known composition....

Lactose is the usual source of energy for multiplication of Lactobacillus casei (Orla-Jensen, Holland) in milk, but when milk is made into cheese the lactose content usually is depleted within a few days. Even then, in such cheese as Cheddar, lactobacilli may continue to increase in numbers until 6 to 12 months after the cheese is made, thus demonstrating the ability of these organisms to utili...

We have investigated the effect of orally administered Lactobacillus casei Shirota (L. casei) on immunological memory, as measured by delayed-type hypersensitivity (DTH) and acquired cellular resistance (ACR). The studies were performed in animal models in which the animals were rendered immune by a primary Listeria monocytogenes infection. It was shown that orally administered viable L. casei,...

Bu çalışmada ultrason uygulamasının farklı probiyotik laktobasil (Lactobacillus acidophilus, Lactobacillus casei, rhamnosus GG) türlerinin canlılığına etkisini incelenmiştir. Ayrıca, fermentasyon süresine etkisi de saptanmıştır. amaçla süte önce 15 dk süreyle 400 W uygulanmış ve kültür ilavesi sonrasında da 5 100 uygulanarak süresi belirlenmiş elde edilen yoğurt benzeri fermente süt ürününde ba...

materials and methods s. sonnei and s .flexneri was identified by common microbiological and serological methods. antibiogram with 18 antibiotics were tested for 34 positive cultures by disc diffusion method. the samples showed considerable resistance to antibiotics. antimicrobial effects of cfcs were tested against s. sonnei and s. flexneri by agar-well assay and broth micro dilution methods. ...

Under intensive aeration (1.3 l/l min) the associated growth of Rhodotorula rubra GED2 and Lactobacillus casei subsp. casei in cheese whey ultrafiltrate (55 g lactose/l) proceeded effectively for both cultures with production of maximum carotenoids (12.4 mg/l culture fluid). For maximum amount of carotenoids synthesized in the cell, the yeast required more intensive aeration than the aeration n...

We report a sensitive and rapid method for detection of hiochi bacteria by PCR. This method involves the electrophoresis of amplified DNA. Nucleotide sequences of the spacer region between 16S and 23S rRNA genes of 11 Lactobacillus strains were identified by analysis of PCR products. Five primers were designed by analysis of similarities among these sequences. A single cell of Lactobacillus cas...
