Several presumptive tests were evaluated for their effectiveness in differentiating streptococci. When the tests were combined into a battery and the resulting reactions were interpreted as patterns, the overall presumptive identification rate was at least 97%. We used the hemolytic reaction, susceptibility to bacitracin and sulfamethoxazole plus trimethoprim (1.25 micrograms plus 23.75 microgr...

Lactococcus lactis subsp lactis BSA (L. lactis BSA) was isolated from a commercial fermented product (BSA Food Ingredients, Montreal, Canada) containing mixed bacteria that are used as starter for food fermentation. In order to increase the bacteriocin production by L. lactis BSA, different fermentation conditions were conducted. They included different volumetric combinations of two culture me...

The present study reports a double enrichment cum selective isolation based protocol for successful isolation of lactic acid bacteria (LAB) from freshwater fish intestine where it exists in substantially lower population counts. The procedure involved enrichment of homogenized intestinal samples of freshwater fish in de Man, Rogosa and Sharpe (MRS) broth medium followed by further enrichment cu...

Ergo is a naturally processed indigenous fermented dairy product, which is commonly prepared at household level and consumed in Ethiopia. The fermentation of this product is lactic acid bacterial dominated process. During this study 500 lactic acid bacterial isolates were recovered from ergo and tested for antagonism against four foodborne pathogens (E. coli O57:H7, Salmonella typhimurium DT104...

Background: Lactobacillus plantarum isolated from fermented olives has been extensively studied with the aim of its use in starter cultures for olive or other production fermentations, but little is known about its antimicrobial resistance and its probiotic effects. Objectives: The aim of this study was to determine the antimicrobial activity using different strains of L. plantarum isolated fr...

BACKGROUND In vivo hepatic phosphorus-31 magnetic resonance spectroscopy (MRS) provides non-invasive information about phospholipid metabolism. AIMS To delineate MRS abnormalities in patients with chronic ductopenic rejection (CDR) and to characterise spectral changes by in vitro MRS and electron microscopy. PATIENTS AND METHODS Sixteen liver transplant recipients (four with CDR; 12 with go...

Cell immobilization is an alternative to microencapsulation for the maintenance of cells in a liquid medium. However, artificial immobilization carriers are expensive and pose a high safety risk. Okara, a food-grade byproduct from soymilk production, is rich in prebiotics. Lactobacilli could provide health enhancing effects to the host. This study aimed to evaluate the potential of okara as a n...

INTRODUCTION: Bile is a biofluid synthesized in the liver and stored in the gallbladder. It facilitates the emulsification, digestion, and absorption of lipids. Study of bile composition is valuable in the diagnosis of various hepatopancreatobiliary diseases. In vitro H MRS studies performed on bile samples collected during endoscopic retrograde cholangiopancreatography (ERCP) have shown diagno...
