Abstract:
... Many reports indicate that intercropping, which usually consists of growing two species next to each other, reduces the incidence of microbial diseases. Besides mechanisms operating at the field level, like inoculum dilution, there is recent evidence that plant-centered mechanisms with identified plant molecules and pathways are also involved. First, plants may trigger the induction of resistance ...

Abstract:
... Biomethane Potential (BMP) test continues to be a useful and inexpensive assay to estimate the digestibility and maximum methane production of various organic substrates in anaerobic digestion or co-digestion processes. Despite its usefulness and several published efforts toward standardizing it, the BMP test still do not follow a universally accepted standard protocol. This makes the comparison o ...
