In vitro Antioxidant Potential of Cell Free Supernatant of Probiotic Bacteria
Open accessAbstract
Probiotic micro-organisms such as lactic acid bacteria are very useful antioxidants which have potential to reduce free radicals in human body. The aim of the present study was to determine the in vitro antioxidant potential of cell free supernatant (CFS) of two probiotic bacteria i.e. Lactobacillus plantarum KP894100 and Lactobacillus acidophilus KP942831. The CFS of L. plantarum KP894100 and L. acidophilus KP942831 showed potent DPPH, superoxide and hydroxyl radical scavenging activity with concentration dependent manner when compared with ascorbic acids as standard drug. Protein contents present in CFS of L. plantarum KP894100 was 12 mg/ml and in L. acidophilus KP942831 was 8 mg/ml was determined by Lowry methods.

Bharti et al. demonstrated remarkable antioxidant activity for an L. acidophilus strain, with intensity correlated to CFS concentration.
“Additionally, a study by Bharti et al.71, also demonstrated remarkable antioxidant activity for an L. acidophilus strain, with the intensity correlated to the concentration of the CFS.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
