Abstract

SULPHATES 99 taining magnesium and ferrous sulphates as the sole source of sulphur.2. This has demonstrated the universal import- ance of inorganic sulphates in the metabolism of moulds, since all species or strains tested utilized 10 % or more, 56 utilized 60 % or more, and 16 over 90 % of the inorganic sulphate in the medium.3. A more detailed examination of the sulphur metabolism of seven species of Penicillium, six strains of A8pergillu8 terreu.sThom, and one strain of A. fumigatus Fresenius, 'grown on the same medium, revealed the fact that some of them form considerable amounts of 'ethereal sulphates' while others, particularly Penicillium notatum Westling, give large yields of other, probably organic, sulphur compounds, of at present unknown nature.

  • The rumen receives a large volume of saliva (about 1.31 L of saliva is secreted from one parotid gland per day for an adult sheep), which buffers the acidity from VFA.

    “The rumen receives a large volume of saliva (about 1.31 L of saliva is secreted from one parotid gland per day for an adult sheep), which buffers the acidity from VFA (McDougall, 1948), while cecum receives no saliva.”

    From Comparative Analysis of the Microbiota Between Sheep Rumen and Rabbit Cecum Provides New Insight Into Their Differential Methane Production (2018) · cites this paper as McDougall, 1948

    The Results report an average of 1,310 mL per 24 hours from one parotid gland, and the discussion of saliva’s function (p. 104) describes its bicarbonate and phosphate as buffers for acids produced in the rumen. However, the reported average includes a six-month-old lamb, so it is not specifically an average for adult sheep. (LLM, conf=0.88)

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.
