Interactions between Bacterial Inoculants and Native Soil Bacterial Community: the Case of Spore-formingBacillusspp.

Abstract: Microbial diversity can restrict the invasion and impact of alien microbes into soils via resource competition. However, this theory has not been tested on various microbial invaders with different ecological traits, particularly spore-forming bacteria. Here we investigated the survival capacity of two introduced spore-forming bacteria, Bacillus mycoides (BM) and B. pumillus (BP) and their impact on the soil microbiome niches with low and high diversity. We hypothesized that higher soil bacterial diversity wou… Show more

“…The 71 carbon sources were grouped into carbohydrates, carboxylic & acetic acids, and amino acids. The assessment protocol was described in previous studies and was in accordance with Biolog's high cell density phenotypic microarray protocol 24,41 . The substrate utilization was calculated using the area under the utilization curve, and the maximum value for the plate was used to normalize the data across all 71 C sources.…”

“…Mallon et al proposed the principle of the diversity-invasibility relationship, wherein PGPR inoculation, as a form of human-induced microbial invasion, is less likely to succeed in highly diverse communities when available resources and niches for invaders are limited (Mallon et al, 2015). This theory has been tested on the Bacillus genus ( Bacillus pumilus and Bacillus mycoides ) to assess its applicability but discovered the principle does not seem to comply throughout all spore-forming bacteria (Mawarda et al, 2022). Thus, there is no clear answer to which abiotic or biotic factors might primarily determine the proliferation of the members of the Bacillus genus in soil.…”

“…Natural ecosystems show variable resistance to invasion by alien species, and this resistance can be related to species diversity in the system [ 78 ]. Mawarda et al [ 89 ] reported that the response of the soil microbial community to an introduced organism is also contingent on the nature and extent of the invasion disturbance. This is closely linked to the ecological strategies and functional traits of each invader.…”
