Aerobic metabolism in the genus Lactobacillus: impact on stress response and potential applications in the food industry

Zotta, T., Parente, E., Ricciardi, A.·2017·Journal of Applied Microbiology

Abstract

This review outlines the recent advances in the knowledge on aerobic and respiratory growth of lactic acid bacteria, focusing on the features of respiration-competent lactobacilli. The species of the genus Lactobacillus have been traditionally classified as oxygen-tolerant anaerobes, but it has been demonstrated that several strains are able to use oxygen as a substrate in reactions mediated by flavin oxidases and, in some cases, to synthesize a minimal respiratory chain. The occurrence of genes related to aerobic and respiratory metabolism and to oxidative stress response apparently correlates with the taxonomic position of lactobacilli. Members of the ecologically versatile Lactobacillus casei, L. plantarum and L. sakei groups are apparently best equipped to deal with aerobic/respiratory growth. The shift from anaerobic growth to aerobic (oxygen) and/or respiratory promoting (oxygen, exogenous haem and menaquinone) conditions offers physiological advantages and affects the pattern of metabolite production in several species. Even if this does not result in dramatic increases in biomass production and growth rate, cells grown in these conditions have improved tolerance to heat and oxidative stresses. An overview of benefits and of the potential applications of Lactobacillus cultures grown under aerobic or respiratory conditions is also discussed.

Claims other papers make about this one

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

  • 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].”
  • 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].”

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.
