Enhancement of Exopolysaccharide Production of Lactobacillus fermentum TDS030603 by Modifying Culture Conditions
To optimize culture conditions that enhance production of a highly viscous exopolysaccharide of Lactobacillus fermentum TDS030603, a chemically defined medium was examined. The best yield was found to be 199 ± 23 mg/l when 48-hr cultivation was microaerobically performed at 30°C in the chemically defined medium supplemented with 5% glucose and 1% ammonium citrate without pH control. In response...
متن کاملComplete Genome Sequence of Lactobacillus fermentum MTCC 25067 (Formerly TDS030603), a Viscous Exopolysaccharide-Producing Strain Isolated from Indian Fermented Milk
Lactobacillus fermentum MTCC 25067 (formerly TDS030603) is capable of producing a highly viscous slime exopolysaccharide. We report here the complete genome sequence of the strain, which was deciphered by using PacBio single-molecule real-time sequencing technology.
متن کاملLysis of modified walls from Lactobacillus fermentum.
The N and O substitution in wall peptidoglycan from Lactobacillus fermentum was studied in relation to growth phase, as well as the lytic activities and the effect of trypsin on them. The N-nonsubstituted sites were determined by dinitrophenylation techniques. The results indicate that an extensive substitution at the O groups takes place as cells go into the stationary growth phase, concomitan...
متن کاملThe inhibitory effects of Lactobacillus fermentum, Lactobacillus acidophilus and Lactobacillus paracasei isolated from yoghurt on the growth and enterotoxin A gene expression of S. aureus
BACKGROUND: Staphylococcal foodborne intoxication is the most common cause of foodborne illnesses by Staphylococcus aureus strains and most are caused by the enterotoxins of S. aureus. Staphylococcal enterotoxin A (SEA) is the most frequently responsible for staphylococcal food poisoning outbreaks. From a food safety and human health point of view, lactic acid bacteria (LAB) may provide a promi...
متن کاملLactic acid bacterial strains: The lactic acid bacterial strains namely, Lactobacillus fermentum 141, Lactobacillus casei 297, Lactobacillus fermentum 156, Lactobacillus rhamnosus 18, Lactobacillus delbruckii
Objective: The objective of the present study was to collect different Lactic acid bacterial strains from culture collection centers and screen their functional probiotic characteristics such as acid tolerance, bile tolerance, antibacterial activity and antibiotic sensitivity for their commercial use. Materials and Methods: Acid and bile tolerence of selected LAB(Lactic acid bacteria) was deter...
