This study aims to determine the use of probiotics Lactococcus lactis and Lactobacillus casei. on analysis laying hens infected with Escherichia coli. A total 120 aged 25 weeks were divided into 6 treatments. Each treatment included 4 repetitions, each which 5 hens. The treatments factor a, namely infectious non-infectious escherichia coli B, AGP, basal feed probiotics.. result this research sh...

We found that species combinations such as Lactobacillus casei subsp. rhamnosus IFO3831 and Saccharomyces cerevisiae Kyokai-10 can form a mixed-species biofilm in coculture. Moreover, the Kyokai-10 yeast strain can form a biofilm in monoculture in the presence of conditioned medium (CM) from L. casei IFO3831. The active substance(s) in bacterial CM is heat sensitive and has a molecular mass of ...

We describe an unusual case of Lactobacillus casei bacteraemia in a heavy dairy consumer woman, with a one month history of low grade fever and admitted to our hospital for sudden onset of severe thoracic pain due to dissection of the aortic arch and ascending aorta. The patient underwent four weeks of intravenous ampicillin (2 g every 4 hours) followed by 2 weeks of oral amoxicillin (1 g every...

Synbiotic yogurt is a that contains probiotics and prebiotics one type of functional food. This study aims to determine the effect addition L. casei ambon banana flour on chemical characteristics synbiotic yogurt. The was conducted using randomized group design with two treatments, namely starter concentration flour. Starters used: 1) Steptococcus thermophilus Lactobacillus bulgaricus; 2) therm...

A method is described for the continuous-flow automation of the serum folate assay using Lactobacillus casei. The total incubation period is approximately four hours. The growth response of the organism to folate is estimated by measuring the rate of reduction of 2,3,5-triphenyl tetrazolium chloride (TTC). A simple continuous culture apparatus is used to grow the inoculum. Supplementation of th...

1. The response of Lactobacillus casei was measured for a number of the monoglutamyl forms of folate derivatives. 2. At the concentrations of folate commonly used in the assay of folate vitamin in foods the response of L. casei to folic acid, (pteroylglutamic acid) and 5-formyl-tetrahydrofolic acid was similar, but 5-methyl-tetrahydrofolic acid gave as little as half the response of folic acid....

In this study the growth of genetically modified Lactobacillus casei LAB6, overexpressing proline iminopeptidase PepI and its capacity to increase free proline was investigated during ripening of Edam cheese. The strain successfully survived 12 weeks of ripening period in cheese. The food-grade plasmid pLEB604, carrying the pepI gene, was stable, and PepI enzyme was active in LAB6 cells isolate...

Los microorganismos ácido lácticos poseen un efecto benéfico en el engorde de los cuyes, al mejorar la degradación materia orgánica y prevenir salmonelosis. El objetivo fue evaluar microrganismos acido levaduras como suplemento las raciones para cuyes (Cavia porcellus) Ayacucho. Se activaron bacterias caldo lactosado a 37°C por 48 horas anaerobiosis, través diluciones consecutivas se sembró aga...
