DOI: 10.1021/acs.est.4c11857
Abstract: Microbial interactions, such as cross-feeding and competition, are crucial in the bioremediation of recalcitrant organic pollution. However, information regarding the metabolic interactions and associated mechanisms during bioremediation remains scarce. This study used a bottom-up approach… read more here.

DOI: 10.1073/pnas.2425603122
Abstract: Significance Understanding how diversity is maintained in microbial communities presents a significant challenge, as cross-feeding networks create complex interdependencies between consumer populations that can be hard to disentangle. We address this problem by using methods… read more here.

DOI: 10.1101/2024.02.09.579562
Abstract: Cross-feeding involves microbes consuming the exudates of other surrounding microbes, mediating elemental cycling. Characterizing the diversity of cross-feeding pathways in ocean microbes illuminates evolutionary forces driving self-organization of ocean ecosystems. Here, we uncover a purine… read more here.

DOI: 10.1111/1462-2920.13847
Abstract: Nutrient cross-feeding can stabilize microbial mutualisms, including those important for carbon cycling in nutrient-limited anaerobic environments. It remains poorly understood how nutrient limitation within natural environments impacts mutualist growth, cross-feeding levels and ultimately mutualism dynamics.… read more here.

DOI: 10.1111/1462-2920.15352
Abstract: Cross-feeding of metabolites between co-existing cells leads to complex and interconnected elemental cycling and microbial interactions. These relationships influence overall community function and can be altered by changes in substrate availability. Here, we used isotopic… read more here.
