Growth-Inhibitory Activity of Cladosporium cladosporioides by Cysteine

Abstract

  When Cladosporium cladosporioides was cultured with cysteine, its growth was completely inhibited statically. The growth of C. cladosporioides cultured on potato-dextrose agar plates was also inhibited by the addition of cysteine. The production of ATP in C. cladosporioides was inhibited by cysteine. When a silicone block was incubated with C. cladosporioides, the surface of the block was coated with the biofilm of C. cladosporioides. However, the block containing cysteine was not covered with biofilm. These results indicate that cysteine is useful as a material to prevent the growth of C. cladosporioides.
