1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Flue-cured tobacco (FCT) with irritating and undesirable flavor must be aged. However, the spontaneous aging usually takes a very long time for the low efficiency. Bioaugmentation with functional strains is a promising method to reduce aging time and improve sensory quality. To eliminate the adverse effect of excessive starch or protein content on the FCT quality, we used the flow cytometry to sort Bacillus amyloliquefaciens LB with high alpha-amylase and Bacillus kochii SC with high neutral protease from the FCT microflora. The mono, co-culture of strains was performed the solid-state fermentation with FCT. Bacillus amyloliquefaciens monoculture for 2 days and Bacillus kochii monoculture for 2.5 days achieved the optimum quality. B. amyloliquefaciens-B. kochii co-culture at a ratio of 3:1 for 2 days of fermentation showed a more comprehensive quality enhancement and higher functional enzyme activity than mono-cultivation. Through OPLS-DA model (orthogonal partial least-squares-discriminant analyzes), there were 38 differential compounds between bioaugmentation samples. In co-cultivation, most of Maillard reaction products and terpenoid metabolites were at a higher level than other samples, which promoted an increase in aroma, softness and a decrease in irritation. This result validated the hypothesis of quality improvement via the co-culture. In our study, we presented a promising bioaugmentation technique for changing the sensory attributes of FCT in a short aging time.
