“…Intercropping systems similarly cause changes in inter-root microbial community composition, which are mainly due to fertilization , crop type (Prommer et al, 2020), and changes associated with crop diversity, such as root secretions (Mommer et al, 2016) and soil environmental factors (Stefan et al, 2021). High-throughput sequencing of 16S rRNA is now an established approach (Bhakta et al, 2017) for deep exploration of soil microbial community composition and abundance. Li et al (2022) found that Acidobacteriota and Proteobacteria were the dominant phyla in the maize intercropping system, and Proteobacteria relative abundance in the intercropped maize root soil increased significantly, primarily due to interspecific root interactions resulting in differences in bacterial community structure during intercropping.…”

Frontiers is more than just an open access publisher of scholarly articles: it is a pioneering approach to the world of academia, radically improving the way scholarly research is managed. The grand vision of Frontiers is a world where all people have an equal opportunity to seek, share and generate knowledge. Frontiers provides immediate and permanent online open access to all its publications, but this alone is not enough to realize our grand goals. Frontiers journal seriesThe Frontiers journal series is a multi-tier and interdisciplinary set of openaccess, online journals, promising a paradigm shift from the current review, selection and dissemination processes in academic publishing. All Frontiers journals are driven by researchers for researchers; therefore, they constitute a service to the scholarly community. At the same time, the Frontiers journal series operates on a revolutionary invention, the tiered publishing system, initially addressing specific communities of scholars, and gradually climbing up to broader public understanding, thus serving the interests of the lay society, too. Dedication to qualityEach Frontiers article is a landmark of the highest quality, thanks to genuinely collaborative interactions between authors and review editors, who include some of the world's best academicians. Research must be certified by peers before entering a stream of knowledge that may eventually reach the public -and shape society; therefore, Frontiers only applies the most rigorous and unbiased reviews. Frontiers revolutionizes research publishing by freely delivering the most outstanding research, evaluated with no bias from both the academic and social point of view. By applying the most advanced information technologies, Frontiers is catapulting scholarly publishing into a new generation. What are Frontiers Research Topics?Frontiers Research Topics are very popular trademarks of the Frontiers journals series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area.

We investigated the effects of the complex cultivation of Salvia miltiorrhiza on microbial communities, secretions, yield, and active ingredients, and the mechanism of action between microbial communities, secretions, and S. miltiorrhiza growth and development. Neither maize nor soybean was suitable to grow with S. miltiorrhiza, but sesame significantly increased salvinone content, the active ingredient of S. miltiorrhiza, and Tanshinone IIA, Tanshinone I, and Cryptotanshinone increased by 27.06%, 22.76%, and 26.41%, respectively, which increased the abundance and number of microbial communities in S. miltiorrhiza roots. 16S rRNA results showed that the most abundant bacterial phyla were Proteobacteria and Acidobacteriota, and their number increased with compound planting of sesame and S. miltiorrhiza. Salvia inter-root secretions affected the microbial community and Salvia growth and development, and lipids and lipid-like molecules significantly reduced Salvia yield and active ingredients. Overall, different plant secretions can lead to differences in the natural environment and Salvia root growth and development, and the composite planting of sesame with Salvia can improve inter-root microbial communities, enhance Salvia quality, and make fuller use of land resources.

“…However, many studies have shown that it is difficult to achieve an effective degradation of a particular pollutant by a single strain [37]. On the other hand, microbial consortia have been reported for their tolerance to pollutants and their performance as bioremediation agents of a wide range of contaminants, such as polyaromatic hydrocarbons [38], crude oil [39], and many kinds of heavy metals [40,41,42], including mercury [43,44]. Further research on the metabolic activities of the bacterial consortium and the interaction among strains incorporated in the consortium will enhance the scientific understanding IOP Publishing doi:10.1088/1755-1315/1201/1/012068 7 of effective and environmentally friendly methods for pollutant degradation and contaminated land restoration.…”

The study was conducted to investigate the growth of mercury-resistant bacterial consortium under the influence of different pHs, temperatures, and C:N ratios, as a part of mercury bioremediation research. The consortium consisted of five bacterial isolates selected due to their resistance to HgCl2 up to 100 ppm and was proven to effectively reduce mercury from the culture media. Consortium suspension was inoculated into two sets of media: 1) Tryptic soy broth (TSB) with pHs of 4.8, 6.1, 8.5, and 9.7; 2) Mineral salt with the addition of glucose and peptone to create C:N ratios of 20:1, 30:1, and 40:1 while the pH was set to 7.4. For comparison, a solution containing mercury-contaminated soil was added to the same set of media and regarded as a microbial community. The growth curves show that the bacterial consortium tended to grow better compared to the microbial community, especially in the TSB medium at incubation temperatures of 20 and 35 °C. In the same medium at a temperature of 45 °C, the growth of both consortium and community under high pHs (8.5 and 9.7) was higher than the one under lower pHs (4.8 and 6.1). Meanwhile, in the mineral salt medium, the influence of the inoculant was not remarkable except under an incubation temperature of 35 °C. Moreover, the C:N ratio did not affect the growth of either the bacterial consortium or the microbial community (p > 0.05). The variance analysis also indicated that the growths were significantly different only when the pH was 4.8.
