Abstract

Munawar, Elfita. 2015. Biodiversity of indigenous bacteria and its contribution in the management of contaminated environment: A case study several regions in Indonesia. Pros Sem Nas Masy Biodiv Indon 1: 1359-1363. Bacteria are a microscopic organism, however, occupy the two domains of three domains in the classification system. This means that the bacteria have a very high diversity both in morphology, physiology, and potential. Some polluted locations in the three provinces, i.e.: South Sumatra, Jambi, and West Papua have been carried out exploration and studied microbial contribution in the management of contaminated environments. Methods used include the stages of isolation and identification of bacteria, potential test and application in addressing contaminated environment in the field. Bacterial biodiversity acquired is Nitrosococcus sp. (P1.1.), Enterococcus sp. (P2.3.), Planococcus sp. (P4.5.), Micrococcus sp. (LC.I4), Bacillus sp. (LC.VI3), Pseudomonas sp. (LC.II7), and Xanthomonas sp. (LC.III10), Bacillus coagulan, B. slentimorbus, B. spasteuri, B. freudenrechii, Pseudomonas freudenreichi, P. aeruginosa, its indigenous bacteria that contribute to the restoration of environments polluted of liquid and solid waste from exploration activities and production of petroleum in the province of South Sumatra. Indigenous bacteria found in Jambi include P. pseudoalcaligenes, B. sphaericus, B. megaterium, B. cereus, B. mycoides, and Xanthobacter autotrophicus contribute to the restoration of environments polluted by solid waste from exploration activities and production of petroleum. While bacteria of P. flourescens, P. aeruginosa, and B. coagulan is indigenous bacteria that contribute to the environmental restoration of contaminated of solid waste from exploration activities and production of petroleum in the province of West Papua. The time required to restore the environment polluted by petroleum waste by bacteria not more than eight months, so that meet the applicable provisions, namely a maximum of eight months. Based on these results it can be concluded that each of these locations is found indigenous bacterial biodiversity that can be used to restore the environment that has been polluted by waste oil from exploration and production of petroleum.
