Abstract
Interactions between species and the evolution of strains are important biotic factors determining the microbial community dynamics, with these two processes being deeply intertwined. Cross-feeding is a prevailing mutualistic interaction in natural microbial communities in which metabolites secreted by one microbe can be utilised by another. Constructing synthetic microbial consortia based on cross-feeding is a promising strategy for bioremediation and bioproduction. But how to improve the performance and the stability of consortia remains a challenge. This review discusses the features of two opposite evolutionary directions of cross-feeding consortia over time, providing insights into the factors affecting the evolutionary process. While coevolving, cross-feeding may strengthen with stronger metabolic coupling, deeper growth dependence, and/or deeper evolutionary dependence; then the consortia become reinforced. Conversely, unsuitable environmental conditions can lead to the direct collapse of the cross-feeding consortia due to metabolic decoupling, partner extinction, or cheater dominance. The loss of the fitness advantage and the constraints on the evolutionary ability can also lead to the weakening of cross-feeding. Cross-feeding partners can affect the evolution of focal strains from different aspects, such as niche space, selective pressure, horizontal gene transfer, and evolutionary rate. Analysing cross-feeding from an evolutionary perspective will advance our understanding of microbial community dynamics and enable rational designs of efficient and stable synthetic microbial consortia.
期刊介绍：
The journal is identical in scope to Environmental Microbiology, shares the same editorial team and submission site, and will apply the same high level acceptance criteria. The two journals will be mutually supportive and evolve side-by-side.
Environmental Microbiology Reports provides a high profile vehicle for publication of the most innovative, original and rigorous research in the field. The scope of the Journal encompasses the diversity of current research on microbial processes in the environment, microbial communities, interactions and evolution and includes, but is not limited to, the following:
the structure, activities and communal behaviour of microbial communities
microbial community genetics and evolutionary processes
microbial symbioses, microbial interactions and interactions with plants, animals and abiotic factors
microbes in the tree of life, microbial diversification and evolution
population biology and clonal structure
microbial metabolic and structural diversity
microbial physiology, growth and survival
microbes and surfaces, adhesion and biofouling
responses to environmental signals and stress factors
modelling and theory development
pollution microbiology
extremophiles and life in extreme and unusual little-explored habitats
element cycles and biogeochemical processes, primary and secondary production
microbes in a changing world, microbially-influenced global changes
evolution and diversity of archaeal and bacterial viruses
new technological developments in microbial ecology and evolution, in particular for the study of activities of microbial communities, non-culturable microorganisms and emerging pathogens.
