The similar development in the cell degradation was also
observed in M. caseolyticus cell morphology during the photocatalytic
treatment (Fig. 1b e M. caseolyticus). The normal untreated
M. caseolyticus cells are shown in Fig. 1b e M. caseolyticus A. The cell
was well circled and surrounded by outside cell wall and cell
membranes. The cell wall was much thicker compared with
P. fluorescens. After treated for 30 min (Fig. 1b e M. caseolyticus B),
the cell wall and cell membranes were still intact; however, they
were not as well defined as the control (Fig. 1b e M. caseolyticus A).
Some parts were attached by black particles. After 90 min, the cell
wall and membranes were damaged and cytoplasm leaked out
