Exploring Indigenous Lactobacillus Species from Diverse Niches for Riboflavin Production
Background: Riboflavin has received rather less attention in the past years, but interest is increasing because it is recognized as an essential component of cellular biochemistry, it is one of the vital vitamins required by human, bacteria, animals and plants. Today, bio production of riboflavin is competing with chemically synthesized one. Lactobacilli are well reckoned for their technologica...
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...
متن کاملA general method for selection of riboflavin-overproducing food grade micro-organisms
BACKGROUND This study describes a strategy to select and isolate spontaneous riboflavin-overproducing strains of Lactobacillus (Lb.) plantarum, Leuconostoc (Lc.) mesenteroides and Propionibacterium (P.) freudenreichii. RESULTS The toxic riboflavin analogue roseoflavin was used to isolate natural riboflavin-overproducing variants of the food grade micro-organisms Lb. plantarum, Lc. mesenteroid...
متن کاملThe effect of riboflavin analogues upon the utilization of riboflavin and flavin adenine dinucleotide by Lactobacillus casei.
Since new analogues of riboflavin have been synthesized which inhibit the growth of rats and of microorganisms which require riboflavin (l-3), it was decided to test the effect of some of these compounds upon the utilization of riboflavin and flavin adenine dinucleotide (FAD) for growth of Lactobacillus casei. Other compounds structurally related to riboflavin were also studied. It has been sho...
متن کاملRibM from Streptomyces davawensis is a riboflavin/roseoflavin transporter and may be useful for the optimization of riboflavin production strains
BACKGROUND The bacterium Bacillus subtilis, which is not a natural riboflavin overproducer, has been converted into an excellent production strain by classical mutagenesis and metabolic engineering. To our knowledge, the enhancement of riboflavin excretion from the cytoplasm of overproducing cells has not yet been considered as a target for (further) strain improvement. Here we evaluate the fla...
