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.
