Figure 6. Larval settlement results obtained with strain Ni1-LEM EP fractions separated by HPLC.
(a) The chromatograph shows absorbance of the EP at 220 nm over time (min). The broken line represents fractions showing anti-settlement activity.
(b) Effects of HPLC-separated PE fractions from bacterial strain Ni1-LEM on larvae settlement of C. intestinalis and P. praeputialis after a 48 hrs incubation. All results are means of three replicate trials. Vertical bars = ± standard errors.
