“…There is a great diversity of bacteria that are part of the plant microbiota and that have traits that promote the growth and development of plants in both optimal and stress environments [56,57]. A key factor influencing the beneficial effects of bacterial consortia is the interaction between their members to guarantee a stable long-term co-existence [58].…”

“…Bacterial interactions within a consortium can be classified into three types based on the effects they have on each other: (i) stimulatory or positive, (ii) inhibitory or negative, or (iii) neutral [58]. Positive interactions generally create a network to support individual members through cross-feeding, where one bacterium utilizes the metabolic products produced by another consortium member.…”

“…In mutualism, each of the members need the others to survive since they mutually exchange required substances or mutually remove toxins [59]. In protocooperation, the interaction between species is beneficial to the growth rate of both populations, but is not required for either to persist [58]. Commensalism is a positive one-way interaction, in which one member benefits while the other is unaffected [60].…”

“…In neutral interactions, members of the consortium do not influence or affect one another. Neutralism occurs when two species consume different substances (nutritional divergence) and neither produces compounds inhibitory to other members of the consortium [58].…”

Plant-associated microorganisms play an important role in agricultural production. Although various studies have shown that single microorganisms can exert beneficial effects on plants, it is increasingly evident that when a microbial consortium—two or more interacting microorganisms—is involved, additive or synergistic results can be expected. This occurs, in part, due to the fact that multiple species can perform a variety of tasks in an ecosystem like the rhizosphere. Therefore, the beneficial mechanisms of plant growth stimulation (i.e., enhanced nutrient availability, phytohormone modulation, biocontrol, biotic and abiotic stress tolerance) exerted by different microbial players within the rhizosphere, such as plant-growth-promoting bacteria (PGPB) and fungi (such as Trichoderma and Mycorrhizae), are reviewed. In addition, their interaction and beneficial activity are highlighted when they act as part of a consortium, mainly as mixtures of different species of PGPB, PGPB–Mycorrhizae, and PGPB–Trichoderma, under normal and diverse stress conditions. Finally, we propose the expansion of the use of different microbial consortia, as well as an increase in research on different mixtures of microorganisms that facilitate the best and most consistent results in the field.

“…Apart from physico-chemical parameters, co-occurring organisms can also affect the MOB community composition directly or indirectly (Stein, 2020). Heterotrophic richness has been shown to enhance methane oxidation activity by MOB (Ho et al, 2014), as accompanying organisms can either remove inhibiting substances (e.g., methanol) or provide stimulating factors (e.g., essential nutrients such as cobalamin; Stock et al, 2013;Iguchi et al, 2015;Veraart et al, 2018;Singh et al, 2019). On the other hand, MOB also select for certain heterotrophs by providing organic metabolites (e.g., acetate) or by removing toxic compounds (e.g., formaldehyde; Morris et al, 2013;van der Ha et al, 2013;Oshkin et al, 2015;Gilman et al, 2017;Xing et al, 2018).…”

Environmental and Microbial Interactions Shape Methane-Oxidizing Bacterial Communities in a Stratified Lake

et al. 2020

In stratified lakes, methane-oxidizing bacteria (MOB) are strongly mitigating methane fluxes to the atmosphere by consuming methane entering the water column from the sediments. MOB communities in lakes are diverse and vertically structured, but their spatio-temporal dynamics along the water column as well as physico-chemical parameters and interactions with other bacterial species that drive the community assembly have so far not been explored in depth. Here, we present a detailed investigation of the MOB and bacterial community composition and a large set of physico-chemical parameters in a shallow, seasonally stratified, and sub-alpine lake. Four highly resolved vertical profiles were sampled in three different years and during various stages of development of the stratified water column. Non-randomly assembled MOB communities were detected in all compartments. We could identify methane and oxygen gradients and physico-chemical parameters like pH, light, available copper and iron, and total dissolved nitrogen as important drivers of the MOB community structure. In addition, MOB were well-integrated into a bacterial-environmental network. Partial redundancy analysis of the relevance network of physico-chemical variables and bacteria explained up to 84% of the MOB abundances. Spatio-temporal MOB community changes were 51% congruent with shifts in the total bacterial community and 22% of variance in MOB abundances could be explained exclusively by the bacterial community composition. Our results show that microbial interactions may play an important role in structuring the MOB community along the depth gradient of stratified lakes.

BackgroundMethanotrophs play an important role in mitigating CH4 emissions in ecosystems. They closely interact with other microorganisms forming communities where the cross‐feeding of metabolites, presumably methanol, is essential for the growth and activity of non‐methanotrophs. The experiments in this study were focused on investigating the effect of adding the supernatant from a methanotrophic consortium to pure cultures of Methylomonas methanica.ResultsMethanol dehydrogenase inhibition caused the accumulation of methanol, which resulted in a significant production after 3 hours, with 1.99 mM CH3OH. The addition of the supernatant was associated with the excretion of methanol by M. methanica and enhancement of the CH4 consumption rate, despite a reduction in growth. The maximum methanol concentrations were between 0.7 – 1.5 mM CH3OH.ConclusionThese findings indicate that methanol excretion may indeed be linked to a metabolic imbalance, which could potentially be compensated through the cross‐feeding of metabolites within the methanotrophic community.This article is protected by copyright.
