Tracking transcript abundance changes of D. vulgaris co-cultures with M. maripaludis in fluctuating resource environment

ABSTRACT: Managing tradeoffs through gene regulation is believed to maintain resilience of a microbial community in a fluctuating resource environment. To investigate this hypothesis we imposed a fluctuating environment that required the sulfate-reducing generalist Desulfovibrio vulgaris to manage tradeoffs associated with repeated ecologically-relevant shifts between retaining metabolic independence (active capacity for sulfate respiration) and becoming metabolically specialized to a mutualistic association with the hydrogen consuming Methanococcus maripaludis. Strikingly, the microbial community became progressively less proficient at restoring the environmentally-relevant physiological state after each perturbation. Most cultures collapsed within 3-7 shifts with only a few collapsing later. We d
