Inhibition of plant-pathogenic bacteria by short synthetic cecropin A-melittin hybrid peptides.

abstract：:Methanogens can use H(2) produced by cathodic depolarization-mediated oxidation of elemental iron to produce methane. Thermodynamic consideration of the cathodic depolarization mechanism predicts more oxidation of Fe at lower pH. Methanogenic responses to pH by Methanococcus deltae, Methanococcus thermolithotrophicus,...
