Francois, in my second attempt at a Reblochon, I used PLA LYO from Danisco (which contains: B. linens, Arthrobacter nicotianae, Debaryomyces hansenii, and Geo. Candidum.) Not knowing this composition at the time of use, I also added a pinch of Geo and B. linens on top of that, now I am getting a bright yellow almost fluorescent coloration. Do you think I used too much B.linens? Another member told me that the yellow will eventually go away, I was curious in knowing what the science behind it is, or what reaction causes the yellow color.
