Abstract

Cephalosporin production by Streptomyces clavuligerus is regulated by some type of carbon catabolite control. Increasing concentrations of preferred carbon sources, such as glycerol and maltose, decreased production of the antibiotics. Poorer carbon sources, such as alpha-ketoglutarate and succinate, led to high specific production of cephalosporins and shifted the dynamics of fermentation to a greater degree of association with growth. The results support the concept that the phase in which a product is made by a microorganism is not a function of the particular molecule produced, but rather of the nutritional environment presented to the organism.

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?

  • S. clavuligerus is unable to assimilate glucose.

    “As S. clavuligerus is unable to assimilate glucose, various compounds have been studied as C3 precursor candidates to ensure proper formulation of fermentation media and improve the yield of clavulanic acid (Aharonowitz and Demain, 1978; Garcia-Dominguez et al., 1989; Pérez-Redondo et al., 2010).”

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.
