Abstract

Oxygen is considered one of the main factors affecting probiotic bacteria survival due to the induction of oxidative damages caused by the action of reactive oxygen species (ROS). It has been shown that oxidative stress resistance in lactic acid bacteria is strongly dependent on the type of cell metabolism. Shift from fermentative to respiratory metabolism (through the addition of heme and menaquinone and in presence of oxygen) was associated to increase in biomass, long term survival and production of antioxidant enzymes. The aim of this work was to investigate the effect of aerobic (presence of oxygen) and respiratory (presence of oxygen, heme end menaquinone) cultivation on the growth kinetic, catalase production, oxygen uptake and oxidative stress response of Lactobacillus johnsonii/gasseri strains previously isolated from infant faeces. Seven strains showed to consume oxygen under aerobic and respiratory conditions. The strain AL5 showed a catalase activity in both growth conditions, while AL3 showed this activity only in respiratory condition. Respiratory condition improved their tolerance to oxidative compounds (hydrogen peroxide and ROS generators) and further they showed promising probiotic features. The exploration of respiratory competent phenotypes with probiotic features may be extremely useful for the development of competitive starter or probiotic cultures.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Oxygen influences lactic acid bacteria metabolism, and air infiltration results in decline of lactic acid concentration in maize silage and barley silage.

    “However, oxygen influences LAB metabolism [46][47][48], and similar to our findings, other studies have reported that air infiltration results in the decline of lactic acid concentration in maize silage [10,11,13] and also in barley silage [12].”
  • The shift from fermentative to respiratory metabolism in lactic acid bacteria triggers early entrance into stationary phase and reroutes pyruvate away from lactate or lactate and ethanol, resulting in acetate accumulation.

    “The shift from fermentative to respiratory metabolism triggers in LAB an early entrance into the stationary phase along with marked changes in final products profiles, rerouting pyruvate away from lactate or from lactate and ethanol, respectively, in homofermentative and heterofermentative lactobacilli, resulting in acetate accumulation [46][47][48].”

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.
