Sodium bicarbonate enhances biocontrol efficacy of yeasts on fungal spoilage of pears
Abstract
The addition of 2% (w/v) sodium bicarbonate (SBC) in the suspensions of antagonistic yeast Cryptococcus laurentii or Trichosporon pullulans significantly limited spore germination and germ tube elongation of Penicillium expansum and Alternaria alternata in potato dextrose broth (PDB) medium. Biocontrol activity of C. laurentii or T. pullulans against postharvest decay caused by P. expansum and A. alternata in pear fruits was significantly increased when C. laurentii or T. pullulans combined with SBC. Combining C. laurentii or T. pullulans with SBC provided a more effective control on P. expansum and A. alternata than applying the antagonistic yeast or SBC alone. Effects of C. laurentii with and without SBC on controlling P. expansum and A. alternata were better than those of T. pullulans. C. laurentii in combination with SBC showed the best control of disease caused by A. alternata in pear fruits.

Improved control of blue mold and black spot of apples or pears, caused by P. expansum and Alternaria alternata, respectively, has been obtained by combining SBC application with a variety of biocontrol agents, mainly yeasts, and other postharvest treatments such as heat or controlled atmospheres.
“Thus, improved control of blue mold and black spot of apples or pears, caused by P. expansum and Alternaria alternata , respectively, has been obtained by combining SBC application with a variety of biocontrol agents, mainly yeasts, and other postharvest treatments such as heat or controlled atmospheres (Yao et al., 2004; Janisiewicz et al., 2008; Janisiewicz and Conway, 2010; Lai et al., 2015).”

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.
