Potensi Bakteri Zoogloea Sp sebagai Bakteri Pembentuk Bioflok pada Sistem Pertambakan

Abstract

The objective of this study was to know the potency of  bacteria zoogloea sp as indigenous bacteria  from shrimp pond farming in colonizing particles. Study of  particle-colonizing capacity of Zoogloea sp by using artificial-sphare agar and transparant exopolimeric particles (TEP) produced by fitoplankton, Thalassiosira weisfloggii. The results showed that Zoogloea sp were able to coloninize both artificial-agar spheres and TEP produced by T. weisfloggii.The mean number of  Zoogloea sp colonizing artificial-agar sphares increasing with incubation time was 2,70 x 10⁴ cells/agar sphere. In the test of TEP-colonizing bacteria showed that Zoogloea sp was able to colonize  the TEP i.e. 2.5 x 10⁸ cells/mL. after 4 days incubation. It can be concluded that Zoogloea sp isolated from shrimp pond farming has a high potential in colonizing particles.
