PERTUMBUHAN TETRASELMIS SP DI MEDIA KULTUR BERBEDA DENGAN PENAMBAHAN PB2+
ABSTRACT: Lead has known as
toxic metal element in water environment which may come from domestic and
industrial waste systems. Recent research proved that microalgae may reduce
lead concentration by using bioaccumulation mechanism to the threshold level
approximately. Tetraselmis is marine microalgae which has sensitive respond to
heavy metal. The research aim was to determined the bioacumulation treshold
effect of specific heavy metal (lead) on marine microalgae Tetraselmis sp. The
research was conducted on July 2010 in BBPBL Hanura Lampung Province. The research
was used two different media (TMRL and Conwy) and each treatment was added lead
of 0,25 mg/l. Data was analyzed by using simple linier regression model to
found the correlation between microalgae density and present of heavy metal.
The result showed that the media has not significant effect on bioaccumulation
ability of Tetraselmis sp. In the other hand, the present of heavy metal on
media has positive correllation to initial concentration of heavy metal on
microalgae biomass (rConwy=0,657; rTMRL=0,682).
