Abstract

Aerobic deterioration of silage following feeding out is responsible for the deterioration of its quality. Inoculation of silage with lactic acid bacteria is one strategy to limit these effects. A trial was performed using whole‐plant corn ensiled in bag silo, and forage was inoculated with Lentilactobacillus buchneri NCIMB 40788 ( Lactobacillus buchneri ) and Lentilactobacillus hilgardii CNCM‐I‐4785 ( Lactobacillus hilgardii ) or not (Control silage). After 159 days of fermentation, the silos were opened and the silage was sampled at 24‐h intervals during a 10‐day aerobic stability assay to measure pH, the fermentation profile, mycotoxins, and microbial and fungal populations. In inoculated silage, lactic acid concentrations and pH remained stable during the aerobic phase and higher microorganism alpha‐diversity was observed. Treated silage was characterized by a high abundance of Saccharomycetes and maintenance of Lactobacillus throughout the aerobic stability assay. The high aerobic stability of the inoculated silage contrasted with the decrease in lactic acid contents and the increase in pH observed in the Control silage, concomitantly with an increase in lactate‐assimilating yeast ( Pichia and Issatchenkia ), and in Acetobacter and Paenibacillus OTUs. Remarkably, Penicillium and roquefortine C were detected in this silage by day 8 following exposure to air. Our study highlighted the fact that the use of L. buchneri with L. hilgardii modified the consequences of exposure to air by maintaining higher microbial diversity, avoiding the dominance of a few bacteria, and preventing fungi from having a detrimental effect on silage quality.

TL;DR

Inoculating whole-plant maize silage with *Lentilactobacillus buchneri* NCIMB 40788 plus *Lentilactobacillus hilgardii* CNCM-I-4785 improved aerobic stability and maintained higher microbial diversity during a 10-day air exposure assay. Control silage deteriorated, with lactic acid depletion, pH rise, lactate-assimilating yeasts and *Acetobacter*/*Paenibacillus* increases, and later *Penicillium* and roquefortine C detection.

Key findings

  • Inoculated silage (LB + LH) was more aerobically stable: time to reach 2°C above ambient was 206.3 ± 26.2 h vs 128.7 ± 32.0 h for Control, and time to 3°C was 224.0 ± 21.7 h vs 144.7 ± 40.4 h (p < 0.001). Maximum temperature was 22.9 ± 1.8°C in LB + LH vs 25.5 ± 1.0°C in Control (p = 0.002), and fresh matter losses averaged 72.7 ± 5.6 g (4.6%) vs 127.7 ± 23.2 g (7.9%) (p < 0.001).
  • During aerobic exposure, Control pH rose from 3.9 to 5.5 and lactic acid fell from 34.4 to 5.2 g kg−1 DM, whereas LB + LH pH remained between 3.97 and 4.10 and lactic acid remained between 26.4 and 22.6 g kg−1 DM. Acetic acid was higher in LB + LH at opening (1.67 vs 1.01 g kg−1 DM) and did not change significantly over time.
  • LB + LH silage had significantly higher alpha-diversity over the 10 days (Shannon index and observed OTUs; reported mean 17.8 vs 10.1, p < 0.001), maintained *Lactobacillus* throughout, and showed increasing *Saccharomyces* abundance, reaching more than 80% by day 10. Control silage was dominated by lactate-assimilating yeasts (*Issatchenkia*, *Pichia*) and later by *Acetobacter* (87.6% by day 9) and *Paenibacillus* (11.5% by day 10).
  • *Penicillium* OTUs became significantly more abundant in Control from day 7, reaching 39.2% abundance by day 7, while mean daily *Penicillium* abundance never exceeded 0.9% in LB + LH. Roquefortine C remained below detection until day 6 and reached 1378.0 µg kg−1 DM after 10 days in Control, but was below detection throughout in LB + LH; DON increased to a mean of 144.0 µg kg−1 DM by day 10 in Control and generally remained below detection in LB + LH.

Methods

  • Whole-plant corn (hybrid Mycogen TMF2Q419) was harvested at 383 g kg−1 DM, ensiled in bag silos, and treated with water (Control) or *L. buchneri* NCIMB 40788 plus *L. hilgardii* CNCM-I-4785 (LB + LH), each at 2 × 10^5 CFU g−1 fresh forage, with n = 5 field-based replications per treatment. Silos were opened after 159 days of fermentation.
  • Aerobic stability was assessed by the Honig method: 1-kg silage layers in 7-L containers at 20°C, with temperature probes and data loggers. A separate succession trial sampled 3 replications per treatment per day over 10 days of air exposure.
  • Analyses included pH, fermentation products (lactic acid, VFA, ethanol, ammonium), microbial counts, 16S V4 and ITS1 amplicon sequencing, and non-targeted LC/MS mycotoxin screening. Statistics included two-way ANOVA, Kruskal–Wallis tests, Kaplan–Meier analysis for aerobic stability, and edgeR for differentially abundant OTUs.

Limitations

  • Stated: the mechanisms behind reduced mycotoxins and improved stability require further work; it is not clear whether DON increases came from fungal activity or conversion of DON-conjugates/glycosides; yeast classification may have been affected by ITS database errors; fungal population heterogeneity in LB + LH may relate to mold counts below detection; mycotoxin variability among the three replications was high.
  • Evident from the text: the trial used one corn hybrid, one harvest location, bag silos, and a 10-day laboratory aerobic stability assay, so broader field and feed-out conditions are not represented; the succession trial used three replications per treatment per day; mycotoxin analysis was semi-quantitative.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • FB1 effect is described as both significant and nonsignificant

    Major

    The results say the FB1 concentration was numerically lower with inoculation but the difference was not significant. The discussion instead claims a significant decrease from inoculation.

  • Reported ethanol range conflicts with Table 2

    Minor

    The discussion gives an ethanol range of 3.4-3.8 g kg−1 DM for LB + LH during exposure to air, but Table 2 reports 6.00 g kg−1 DM on day 1 and 4.57 on day 10, among other values outside that range.

  • Differential-abundance cutoff has opposite inequality

    Minor

    The methods define differentially abundant OTUs using a logFC of at least 1.5, whereas the Figure 3 caption specifies a logFC of at most 1.5.

  • Final Control lactic-acid ratio is not 0.3

    Minor

    The discussion says the Control lactic-acid-to-VFA ratio decreased to 0.3, but Table 2 reports 14.5% (0.145) on the last day of exposure.

  • Acetic acid treatment comparison reverses during exposure

    Minor

    The stated concentrations during aerobic exposure are 1.67 g kg−1 DM for Control and 0.72 for LB + LH. That reverses the subsequent statement that acetic acid concentration was higher in LB + LH silage.

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.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-09.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-09.

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.
