The current study aimed to improve riboflavin production by native bacterial isolates and medium components. Bacterial species Bacillus subtilis ASU8 (KU559874) and Bacillus tequilensis ASU9 (KU559876) showed high potentiality for riboflavin production. The optimal growth and riboflavin production were achieved after 48 h. The impact of glycine addation to the basal medium was explored by apply...

It has been known for many years that a number of different nutritional deficiencies lower the efficiency of food utilization. For example, riboflavin-deficient rats consume 15 to ‘20% more calories than are required to maintain control animals at the same weight (1). The lowered efficiency of food utilization in riboflavin deficiency has been attributed in part to incomplete oxidation of nutri...

By means of paper chromatography, Lactobacillus casei test and the staining method with the Feulgen reaction, the effects of reserpine and amphetamine on riboflavin and melanin were studied in the liver of Triturus cristatus. It was demonstrated that the concentrations of both melanin and riboflavin can be altered by the influence of these drugs. From the results obtained it is suggested that r...

[These two figures were sent for Dr. 0. P. Verma's paper on ' Further Experience of the Treatment ol Superficial Keratitis with Riboflavin' in our August number : they were however too late for inclusion and with his permission they are now being used to illustrate Dr. M. Swaminathan's paper ' Riboflavin and Its Role in Nutrition '.?Editor, I. M.. G.] RIBOFLAVIN AND ITS HOLE IN NUTRITION : M. S...

etary riboflavin, neither were they related to EGRAC or plasma ribofla-vin. This supports the use of EGRAC, and, to a lesser extent, plasma ribo-flavin, as a marker of riboflavin status that reflects dietary intake. We do not agree with the suggestion that the improvement in folate status in the folate-rich diet should have compromised riboflavin status, as it did in the folic acid supplemen-ta...

A number of chemical methods have been described for the determination of riboflavin (1-13). These methods are in general limited in use because, when applied to certain products, either they are not specific for riboflavin or all the riboflavin present is not recovered (2). In most cases the authors of papers presenting riboflavin methods have indicated that the methods are of limited applicat...

The possibility of an interrelationship between vitamins of the B group was first suggested by clinical observations. Scandinavian authors (l-3) have reported that treatment of multiple deficiencies with thiamine alone precipitated the appearance of lesions characteristic of nicotinic acid deficiency, and Sydenstricker (4) encountered the enhancement of certain signs of deficiency in pellagrins...

BACKGROUND Riboflavin is known to protect tissue from oxidative damage but, to our knowledge, has not been explored as a means to control exercise-related muscle soreness. This study investigated whether acute ingestion of riboflavin reduces muscle pain and soreness during and after completion of a 161-km ultramarathon and improves functional recovery after the event. METHODS In this double-b...

Development of a reliable marker of adherence to high-fiber diets is essential for accurately assessing dietary fiber intake in community interventions and clinical trials. The objective of this study was to evaluate the feasibility of using a riboflavin tracer incorporated into wheat bran cereal to determine fiber intake and compare results to the more traditional methodology of measuring stoo...

With the huge negative impact of neurological disorders on patient's life and society resources, the discovery of neuroprotective agents is critical and cost-effective. Neuroprotective agents can prevent and/or modify the course of neurological disorders. Despite being underestimated, riboflavin offers neuroprotective mechanisms. Significant pathogenesis-related mechanisms are shared by, but no...
