technical and process parameters for high cell density culture and the research and development of biological algicide were investigated. In the stage of high cell density culture
we selected the appropriate cell culture medium of bacteria L7 (carbon and nitrogen source are glucose+NH
4
Cl
C/N ratio is 3∶1
pH 7.5)
bacterial load (3.1×10
7
cfu/mL)
DO (30%(±10%)) and agitation speed (160(±10) r/min) through the setting of single factor experiment and orthogonal experiment
the application of shake flask and automatic fermentor. The process of purify and identify algicidal components of L7 included dialysis
gel chromatography
HPLC
MS and et al. Finally two algicidal components were received
the molecular weights were 588.2 and 365.0 respectively
and the algicidal effect of the latter one weas better.
