Bacterial networks illustrating the effect of grass (GRA) and grass hay (HAY) on the relationships between the different bacterial genera in the liquid phase in the Rusitec system. Edges represent positive (green) and negative (red) correlation coefficients between genera (r > 0.7 and adjusted P < 0.05).
