    Metabolic modulations of Pseudomonas graminis in response to H2O2 in cloud water

    In cloud water, microorganisms are exposed to very strong stresses especially related to the presence of reactive oxygen species including H2O2 and radicals, which are the driving force of cloud chemistry. In ord...
