Physiological studies on the solid‐state quinoa tempe fermentation, using on‐line measurements of fungal biomass production

Peñaloza, Walter, Davey, Christopher L, Hedger, John N, Kell, Douglas B·1992·Journal of the Science of Food and Agriculture

Abstract

A quantitative approach to the on‐line measurement of fungal biomass, based on the biomass‐dependent changes in electrical capacitance at 0.30 MHz, was exploited to optimise the solid‐substrate tempe fermentation of Chenopodium quinoa Willd by Rhizopus oligosporus Saito. Variables including the mould strain, the initial pH, the inoculum density and the substrate moisture content influenced the mycelial development and quality of quinoa tempe prepared in petri dish fermentation units. It was found that R oligosporus isolate UCW‐FF8001 at an inoculation density of 3.3 × 10 4 colony forming units per gram of quinoa substrate at 620 g kg−1 moisture content yielded both the highest biomass and the best quality tempe.

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.
