Background and Objectives: Lactobacillus delbrueckii ssp bulgaricus is widely used in dairy industries as a starter for yogurt production. This study was designed using response surface methodology (RSM) in 12 batch pH-controlled cultures of Lactobacillus delbrueckii sub-ssp. bulgaricus for determining the effect of temperature and pH on the biomass production of a native strain of L. bulgaricu...

Lactobacillus and thrush prevention A randomised controlled trial1 has dashed the hope that eating, or putting preparations of lactobacillus into the vagina, prevents thrush. The aim of the study published in the British Medical Journal was to test whether oral or vaginal lactobacillus could prevent postantibiotic vulvovaginitis. The study recruited women aged 18–50 years with nongynaecological...

The outlines of antibiotic resistance of some probiotic microorganisms were studied. This study was conducted with the double purpose of verifying their ability to survive if they are taken simultaneously with an antibiotic therapy and to increase the selective properties of suitable media for the isolation of samples containing mixed bacterial populations. We isolated from commercial dairy and...

Abstract The high and easy degradable sugar content of source-sorted organic household (SSOHW) suggests it as a promising candidate for fermentative lactic acid production. present study aimed to apply bio-augmentation strategy with different bacteria (Lactobacillus delbrueckii or Pediococcus acidilactici) improve production from non-sterile SSOHW. optimum operational temperature, initial pH to...

BACKGROUND Research from developing countries, such as Nigeria, on Lactobacillus species in the female urogenital tract and their role as a barrier to vaginal infection is limited. Therefore, the aim of this study was to assess the clinical biotherapeutic potential of indigenous Lactobacillus species. METHODS Antimicrobial metabolites production were characterised using simple and easily repr...

Our previous analysis of 65 advanced dental caries lesions by traditional culture techniques indicated that lactobacilli were numerous in the advancing front of the progressive lesion. Production of organic acids by lactobacilli is considered to be important in causing decalcification of the dentinal matrix. The present study was undertaken to define more precisely the diversity of lactobacilli...

In this study, two main probiotics (Lactobacillus plantarum and Lactobacillus delbrueckii subsp < em>. bulgaricus) were isolated from the intestine of Tor grypus and their effects on growth performance, gut microbial flora and digestive enzymes activities (i.e., α-amylase, lipase, trypsin, chymotrypsin, and alkaline phosphatase) of Tor grypus (Karaman, 1971) were determined. Juveniles of T. gry...

A series of in vitro experiments was arranged to assess effects of different concentrations of H(2)O(2) contained in bacterial cultures on apoptosis and necrosis of HT-29 line cells representing human gut epithelium. On the basis of cytofluorimetric assays it was possible to demonstrate that supernatant of the Lactobacillus strain producing hydrogen peroxide (L. delbrueckii CU/22) was able to i...
