 Amycel San Juan Bautista is also the site for production of the inoculum used at all Amycel spawn plants. Culture maintenance and inoculum production activities are conducted by technicians with many years of experience in all phases of spawn production. Master cultures are preserved in liquid nitrogen for long term stability with duplicate cultures stored at the Biotechnical Research Laboratory.  

 Amycel San Juan Bautista is the home office for the company, not only for inoculum production, but for business administration and process development.
