Lactobacilli constitute an important group of non-pathogenic Gram-positive bacteria commonly found in foods like dairy products, beverages, fruits, vegetables and fermented meat as well as used in the preservation of plant-originated foods and feeds. Members of the genus Lactobacillus are also present in human and animal gastrointestinal (GI) and urogenital tract [Tannock 1995]. Lactobacilli, a...

The two csp-like genes from the lactic acid bacterium Lactobacillus delbrueckii ssp. bulgaricus were characterized and designated cspA and cspB. The gene cspA has been identified using a polymerase chain reaction (PCR)-based approach with degenerated primers and further characterized using an inverse PCR strategy. cspA encodes a protein of 65 amino acid residues which displays between 81 and 77...

Abstract Nowadays, the consumption of probiotic yogurt has been a significant increase. Mostly people prefer to consume yoghurt because its taste and high nutrients. However, in manufacturing process yogurt, thermal causes some nutritional losses, e.g. , ?-carotene. Therefore, replace loss ?-carotene during this process, then added an extract Podang Urang mango ( Mangifera indica L.). Mango is ...

El yogurt es un alimento funcional resultado del proceso de fermentación la leche producida por Lactobacillus delbrueckii subsp. bulgaricus y Streptococcus thermophilus Thermophilus. Los carbohidratos totales son alrededor 4 % corresponden a los azúcares que degradados lactosa, como galactosa glucosa generación ácido láctico. bajo pH generado el láctico promueve uso endulzantes mejoren aceptabi...

The residual activity of Lactobacillus delbrueckii ssp. bulgaricus cultures was analysed using pH and various impedimetric methods (impedance detection time (IDT), conductance and capacitance) to quantify the loss in activity following freeze-drying. The large variation recorded in IDT values for similar levels of activity suggests that IDT is not an adequate parameter for estimating the cultur...

The structural genes gap, pgk and tpi encoding three glycolytic enzymes, glyceraldehyde-3-phosphate dehydrogenase (GAPDH), 3-phosphoglycerate kinase (PGK) and triosephosphate isomerase (TPI), respectively, have been cloned and sequenced from Lactobacillus delbrueckii subsp. bulgaricus (L. bulgaricus). The genes were isolated after screening genomic sublibraries with specific gap and pgk probes ...
