Beyond being simply positive or negative, beneficial or inhibitory, microbial interactions can involve a diverse set of mechanisms, dependencies and dynamical properties. These more nuanced features have been described in great detail for some specific types of interactions, (e.g. pairwise metabolic cross-feeding, quorum sensing or antibiotic killing), often with the use of quantitative measurements and insight derived from modeling. With a growing understanding of the composition and dynamics of complex microbial communities for human health and other applications, we face the challenge of integrating information about these different interactions into comprehensive quantitative frameworks. Here, we review the literature on a wide set of microbial interactions, and explore the potential value of a formal categorization based on multidimensional vectors of attributes. We propose that such an encoding can facilitate systematic, direct comparisons of interaction mechanisms and dependencies, and we discuss the relevance of an atlas of interactions for future modeling and rational design efforts.

Plants and microorganisms coexist within complex ecosystems, significantly influencing agricultural productivity. Depending on the interaction between the plant and microbes, this interaction can either help or harm plant health. Microbes interact with plants by secreting proteins that influence plant cells, producing bioactive compounds like antibiotics or toxins, and releasing molecules such as N-acyl homoserine lactones to coordinate their behaviour.

Sebaceous free fatty acids are metabolized by multiple skin microbes into bioactive lipid mediators termed oxylipins. This study investigated correlations between skin oxylipins and microbes on the superficial skin of pre-pubescent children (N = 36) and adults (N = 100), including pre- (N = 25) and post-menopausal females (N = 25). Lipidomics and metagenomics revealed that Malassezia restricta positively correlated with the oxylipin 9,10-DiHOME on adult skin and negatively correlated with its precursor, 9,10-EpOME, on pre-pubescent skin.

Background: The rumen fluke, Calicophoron daubneyi, is the major paramphistome species infecting ruminants within Europe. Adult flukes reside within the rumen where they are in direct contact with a unique collection of microorganisms. Here, we report a 1.

The hydrogen-based partial denitrification coupled with anammox (H-PDA) biofilm system effectively achieves low-carbon and high-efficiency biological nitrogen removal. However, the effects and biological interaction mechanism of H flux with the H-PDA system have not yet been understood. This study assessed the effects of H flux on interactions among anammox bacteria (AnAOB), denitrifying bacteria (DB), and sulfate-reducing bacteria (SRB) coexisting in a H-PDA system.

Although single bacteria have been applied to the Polycyclic Aromatic Hydrocarbons (PAHs) remediation, its efficacy is severely restricted by long degradation periods and low efficacy. A microbial symbiotic system founded by two or more bacterial strains may be an alternative to traditional remediation approaches. Its construction is, however, hampered by antagonistic interactions and remains challenging.
