The indicator analysis showed that these differences were quite significant at the genus level.

Acidobacteriae and Agaricales with linear discriminant analysis (LDA) scores >5.0 exhibited highly significant differences in the bacterial and fungal communities of CS and CR, respectively ( Figures 3b , c ). 3.3 Diversity of rhizospheric microbial communities Analysis of beta diversity indicated that, in terms of bacteria, WR and CR clustered together, and that WS and CS clustered together ( Figure 4a );

In the present study, the ED group showed a trend toward lower alpha diversity, but this difference was not statistically significant.

In contrast, the Chao1 index of the CK group showed an increasing trend, and the Shannon and Chao1 indices of the CK2 group were significantly higher than those of the CK0, CK1, and BIO2 groups ( p < 0.05).

The Shannon index of the BIO group after disease onset showed an increasing and then decreasing trend, whereas the Chao1 index showed a decreasing trend.

The differences were taken as significant at the p < 0.05 level and highly significant at p < 0.01. 3 Results and analysis 3.1 Apparent digestibility of nutrients As can be seen from Table 3 , with increasing amounts of L. ruthenicum roughage added to the feed, the apparent digestibility of NDF showed a tendency to increase and then decrease ( p = 0.001).

The relative species abundance and bacterial diversity in the bamboo shoot portions both showed an increasing trend in the order U > M > D.

This is because microbial biomarkers are often based on specific fermentation patterns or relatively stable microbial community structures, and in the non-fermentor-driven fermentation dynamic environment, it is difficult to accurately capture markers with real indicative significance, and the dynamic changes of microbial communities represented by these markers become elusive, which can easily lead to mislead the subsequent analysis and conclusion derivation.

T1 and T3 did not show significant increases in exchangeable Mn, whereas T2 and T4 showed highly significant increases in exchangeable Mn.

The interactions between microalgae and bacteria are highly significant in the context of the circular economy, particularly for biomass derived from wastewater remediation that can be utilized as a biostimulant.

Statistically significant means were considered when p < 0.05, while p < 0.1 was considered a tendency toward statistical significance.

The CS group exhibited a decreasing trend in the relative abundance of saprotrophic fungi, likely due to the higher lignocellulose content in CS diets, which limited substrate availability for enzyme secretion and thus suppressed saprotroph proliferation.

Regression analysis reinforced these findings, with citrulline exhibiting a strong positive correlation with NE, as evidenced by a regression coefficient of 2.28 and a highly significant p -value of 3.43E-06.

Similarly, the dominant fungus Saccharomycopsis in Daqu showed a highly significant positive correlation with the fermentation power of the samples ( Kang et al., 2022 ), consistent with the results of this study.

The results showed that the survival rate of strains showed a decreasing trend with either decreasing pH or increasing bile salt concentration.

At the phylum level, Actinobacteria generally showed a decreasing trend, except for a study by Jobira et al.

Specifically, while Bacteroides demonstrated an increasing trend in both humans and mice with PCOS, other taxa exhibited divergent patterns.

Overall, the control sample had an increasing trend, and the TDS was also increased to 900 mg/L. the variation in pH at 24 h was 7.9 at 48 h the pH observed was 7.2 and at 72 h the pH was 7.5 and at 96 h pH increased to 8.

A P -value of < 0.05 indicates a significant difference, while a P -value of < 0.0001 indicates an extremely significant difference. 3 Results 3.1 Fermentation of nattokinase activity by different substrates As illustrated in Figure 1A comparative analysis was conducted to evaluate the differences in enzyme production for nattokinase fermentation using various carbon substrates.

POC, MAOC, and GRSP all exhibited an increasing trend with longer cultivation periods, leading to a significant increase in SOC.

In contrast, butyrate levels were significantly reduced in the duodenum ( p < 0.01) and showed a decreasing trend in the colon, although not statistically significant. 3.5.

Furthermore, the AM fungal diversity index showed a trend toward the dominance of AM fungal diversity in fields with high spore richness; however, this did not necessarily result in higher spore abundance.

The findings reveal a clear trend of reduced virulence, particularly among Gram-positive pathogens.

Overall, the compost C/N ratio exhibited a decreasing trend ( Figure 1e ), This trend was attributed to microbial activity consuming carbon sources (such as sugars, amino acids, etc.), degradation of organic matter, and CO2 emissions ( Yang et al., 2019 ).

The nitrate nitrogen in spring compost showed an increasing trend, while autumn compost exhibited an increase followed by a decrease ( Figure 1g ).
