Impact of OBC and OBC-Mg on soil cation exchange capacity (CEC) During the incubation period, the overall soil CEC showed a decreasing trend after the application of OBC and OBC-Mg with the increase of incubation time ( Figure 3 ).

The application of OBC showed an overall trend of increasing sucrase activity with incubation time.

The soil mineralization rate decreased in all treatments from 0 to 10 days of incubation, and showed an increasing trend in all treatments from 10 to 20 days of incubation.

Available potassium showed an extremely significant correlation with soil microbiome.

Figure 1B shows a decreasing trend in a w of sausage through the entire fermentation process.

p < 0.05 (*) were considered statistically significant, p < 0.01 (**) were considered highly significant.

Nitrate_reduction, aerobic_nitrite_oxidation, and nitrification show a decreasing trend with the increase of stage, whereas animal_parasites_or_symbionts, nitrogen_fixation, cellulolysis, and chemoheterotrophy show an increasing trend as the stage increases.

The ANOVA analysis revealed a highly significant difference in soil moisture contents and pH between the last two successional stages (stage S4 and S5) and the late stages (stage S0, S1, S2, and S3).

Figures 4A , B shows the little difference between MN and MT, while a decreasing trend of 5-HT and an increasing trend of VIP in MR group.

p < 0.05 indicates a significant difference, and p < 0.01 indicates an extremely significant difference.

In August 2021, the Student Health Center reported an increasing trend of students who tested positive for SARS-CoV-2, partly due to the rise of the Delta variant.

On the 14th day after immunization, the antibody level of the experimental group was significantly increased, and the difference was extremely significant compared with the control group, on the 35th day after immunization, the serum IgG antibody levels of CotG-E-G and CotG-C-G in the experimental group reached the highest level ( Figure 2C ).

aeruginosa of the control group entered the logarithmic growth stage after culture for 4 h, and showed an increasing trend to the stable stage until 16 h.

Control group’s fluorescence intensity of 340.33 ± 18.77 on average, after FC3 and FC6 treatment, and the fluorescence intensity increased to 453.67 ± 10.41 and 564.33 ± 14.01 respectively, compared with the control group, with a growth of 33 and 66% respectively, compared with the control group, both were extremely significant differences.

The abundance of beneficial gut microbiota and functional metabolism genes is linked to the health of the species, with those in worse habitats showing a decreasing trend, which indicates that these individuals have a more potential disease risk ( Amato et al., 2013 ; Barelli et al., 2015 ; Trosvik et al., 2018 ; Wasimuddin et al., 2022 ).

(2006) found that invasive strains were associated with specific serotype/gene combinations, but the association was only marginally significant.

Generally, the abundance of Aspergillus increased with the fermentation, while unclassified_f__Saccharomycetales_fam_Incertae_sedis showed a decreasing trend.

In all experimental groups, the NRE showed a trend of a rapid increase in the first 40 h, followed by a decreasing trend during 40–160 h, and high NRE was maintained from 160 h to 180 h.

Results and discussion Carbon release performance Organic carbon release capacity As can be seen from Figure 2A , the carbon sources of the four groups all showed an increasing trend in the early stage of the experiment, while the DOC content of the four experimental groups all decreased and tended to be stable in the later stage.

Compared with S, the concentration of N 2 O in P showed an increasing trend.

However, there were extremely significant differences in rhizosphere bacterial abundance between AH and QS under drought stress.

In both, an increasing trend was observed in the presence and relative abundance of the Streptococcus sp. at the beginning of the sampling season, its peak in February, and then its decrease ( Figures 6 , 7 ).

Furthermore, all path coefficients were extremely significant, except for association between abundant genera and foliar spectral traits in surface soil.

The total nitrogen content showed a decreasing trend during fermentation in the CK, P and M groups ( Figure 4C ).

α = 0.05 was considered the test level, and p < 0.05 indicated that the difference was statistically significant, and p < 0.01 indicated that the difference was extremely significant.
