Hi Tim -

Few fungi actually contain chitin in their cell walls - but quite nicely, the ones that do are the oomycetes, the particularly pathogenic species at that. So, chitin-utilizing organisms will tend to operate AGAINST the pathogen-fungi.

Getting chitinase to be expressed in your compost, compost tea or soil is dependent on putting in materials that feed these organisms. Like chitin - which are high in materials like shrimp shells, and dead insects.

But please be aware that addition of chitin to compost has been patented. WormGold holds the patent for this process of adding chitin to composting operations. As I understand this - and my understanding of patent law is a bit limited, so bear with me here - you cannot advertise your compost as having this ability. WormGold holds the patent on it, so they are the only ones that can claim their compost has chitinase ability.
