Bacillus subtilis KBKU21 shows two functions in food waste recycling system: production of optically active l-lactic acid as a monomer chemicals for bio-plastic, and plant growth promoting activity in the anaerobically-fermented compost from food waste. The photograph shows selective staining of the bacteria in the compost, observing with FITC-derivative of order Bacillales-specific 16S rRNA oligonucleotide probe, BACILI02. With improved staining and capturing conditions (re-valance of RGB color), thick colonization of Bacillales cells around food waste residue can be clearly observed.
