MÔI TRƯỜNG NUÔI CẤY LACTOBACILLI Dịch bởi AI TÓM TẮT: Giới thiệu một môi trường nuôi cấy cải tiến cho vi khuẩn lactobacilli. Môi trường này hỗ trợ sự phát triển tốt của lactobacilli nói chung, và đặc biệt hữu ích cho một số chủng nhạy cảm chỉ phát triển kém trong các môi trường chung khác. Ngoài ra, trong môi trường này không cần sử dụng nước ép cà chua, một nguyên liệu có sự biến đổi cao. Khi được điều chỉnh ...

Enumeration of human colonic bacteria producing phenolic and indolic compounds: effects of pH, carbohydrate availability and retention time on dissimilatory aromatic amino acid metabolismE.A. SMITH AND G.T. MACFARLANE. 1996. Concentrations of phenolic compounds in human gut contents were more than fourfold higher in the distal colon (6.2 mmol kg‐1 ) compared to the proximal bowel (1.4 mmol kg‐1 ). Tryptophan metabolites were never found in more than trace amounts in large intestinal contents and phenol substituted fatty acids were th... ... hiện toàn bộ

Purification, characterization and antimicrobial spectrum of a bacteriocin produced by Pediococcus acidilacticiAn antimicrobial peptide designated pediocin AcH was isolated from Pediococcus acidilactici strain H. The pediocin AcH was purified by ion exchange chromatography. The molecular weight of pediocin AcH was determined by SDS‐PAGE to be about 2700 daltons. Pediocin AcH was sensitive to proteolytic enzymes, resistant to heat and organic solvents, and active over a wi... ... hiện toàn bộ

The effect of pH, salt concentration and temperature on the survival and growth of Listeria monocytogenesFactorially designed experiments have been used to study the growth and survival of Listeria monocytogenes in different combinations of pH and salt concentrations at ambient and chill temperatures. Survival at low pH and high salt concentration was strongly temperature dependent. The minimum pH values that allowed survival after 4 weeks from an initial 10... hiện toàn bộ

The bactericidal, fungicidal and sporicidal properties of hydrogen peroxide and peracetic acidThe antimicrobial properties of aqueous solutions of peracetic acid and hydrogen peroxide have been compared. Peracetic acid exhibited excellent antimicrobial properties, especially under acidic conditions. Reductions by a factor of 106 in the numbers of vegetative bacteria are obtained within 1 min at 25°C using a solution containing 1.3 mmol/l of peracetic acid. Rapi... ... hiện toàn bộ

Relationships Amongst the Fast‐growing Rhizobia of Lablab purpureus, Leucaena leucocephala, Mimosa spp., Acacia farnesiana and Sesbania grandiflora and their Affinities with Other Rhizobial GroupsColony characteristics, growth in litmus milk, precipitation in calcium glycerophosphate medium and utilization of carbon sources of the root‐nodule bacteria isolated from the tropical legumes Leucaena, Mimosa, Acacia, Sesbania and Lablab were similar to fast‐growing rhizobia of temperate legumes, particularly Rhizobium mel... ... hiện toàn bộ

Contribution of the microflora to proteolysis in the human large intestineProtease activities in human ileal effluent were approximately 20‐fold greater than in normal faeces. Comparative studies with faeces from a person who did not have a pancreas suggested that a substantial proportion of the proteolytic activity in normal faeces was of bacterial origin. Thimerosal, iodoacetate, EDTA and cysteine significantly inhibited proteolysis in faeces, but not in small... ... hiện toàn bộ
