- THE EFFECTIVENESS OF RHIZOSPHERE MICROBE ISOLATES ON PARASERIANTHESFALCATARIA AND ENTEROLOBIUM CYCLOCARPUM SEEDLINGS GROWTH IN MERCURYCONTAMINATEDTAILINGS. Utilization of rhizosphere microbes such as arbuscular mycorrhizal fungi(AMF) and mercury-resistant bacteria (MRB) is one of the alternative technologies that can be used synergisticallyto overcome the main problem in biologically rehabilitation of marginal and mercury (Hg) contaminatedtailings in ex gold mining area. The research was aimed to get an effective combination of AMF isolates (Glomussp. SS11, Glomus sp.SS15, Glomus sp.SS18) with MRB isolates (Bacillus sp. HgTA1 and Pseudomonas HgRA) insupporting seedlings growth of sengon laut (Paraserianthes falcataria (L.) Nielsen) and sengon buto (Enterolobiumcyclocarpum Griseb) in mercury-contaminated tailings. Dual inoculation of Glomus sp. SS15 with Bacillussp. HgTA1 or Pseudomonas sp. HgRA isolates; dual inoculation of Glomus sp. SS18 with Bacillus sp. HgTA1 orPseudomonas sp. HgRA isolates; single inoculation or dual inoculation of Glomus sp. SS11 with Pseudomonassp. HgRA isolates were proven to be very effective in increasing P. falcataria seedlings height. However, onlysingle inoculation of Bacillus sp. HgTA1 isolate was effective in increasing E. cyclocarpum seedlings height. Hgaccumulation in plant tissue of P. falcataria and E. cyclocarpum, either with or without rhizosphere microbialinoculation, indicated that both plants were highly potential as Hg phytoextraction or phytostabilization agents
