Multifunctional properties and safety evaluation of lactic acid bacteria and yeasts associated with fermented cereal doughs.

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.
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
Spontaneous cereal fermentations involve diverse lactic acid bacteria (LAB) and yeasts which may include multifunctional and safe or unsafe strains. This study assessed acidification ability, safety, antifungal activity and free amino acids release ability of LAB and yeasts previously isolated from spontaneously fermented cereal doughs in Benin. Fourteen LAB and thirteen yeast strains were studied in liquid media and/or in a model cereal dough prepared in laboratory conditions. Antifungal activity was assessed against Candida glabrata in liquid medium. Amino acids were determined by pre-column derivatization and separation with reversed-phase HPLC. Antimicrobial susceptibility was analysed by minimum inhibitory concentration determination. The acidification ability was higher for LAB compared to yeast strains. All LAB strains retarded the growth of C. glabrata Cg1 with the highest inhibition recorded for Weissella confusa Wc1 and Wc2. The highest free amino acid content was found in the doughs fermented with Pichia kudriavzevii Pk2 and Pk3. All the LAB strains were susceptible to ampicillin, chloramphenicol, erythromycin, but displayed phenotypic resistance to kanamycin, streptomycin and tetracycline. Positive PCR amplicon of resistance genes were detected in the following cases: 2 LAB strains were positive for kanamycin (aph(3)III), 5 strains were positive for streptomycin (aadA and/or strA and/or strB) and 3 strains were positive for tetracycline (tet (L) and/or tet (M)). For yeasts, most of the P. kudriavzevii strains were resistant to amphotericin B, fluconazole and itraconazole opposite to K. marxianus and Saccharomyces cerevisiae strains which were susceptible. The results obtained are valuable for selecting safe and multifunctional strains for cereal fermentation in West Africa.
