“…In recent years considerable attention has been paid to PGPR to replace agrochemicals (fertilizers and pesticides) for the plant growth promotion by a variety of mechanisms that involve soil structure formation, decomposition of organic matter, recycling of essential elements, solubilization of mineral nutrients, producing numerous plant growth regulators, degrading organic pollutants, stimulation of root growth, crucial for soil fertility, biocontrol of soil and seed borne plant pathogens and in promoting changes in vegetation [7]. An understanding of plant growth promoting rhizobacteria and their interactions with biotic and abiotic factors is indispensable in bioremediation techniques [8] energy generation processes and in biotechnological industries such as pharmaceuticals, food, chemical, and mining. Furthermore plant growth promoting rhizobacteria can reduce chemical fertilizers application and economically, environmentally beneficial for lower production cost as well as recognize the best soil and crop management practices to achieve more sustainable agriculture as well as fertility of soil [9].…”

Soil is dynamic living matrix and it is not only a critical resource in agricultural and food security but it is also towards maintenance of all life process. Pathogenic microorganisms affecting plant health are a major and chronic threat to sustainable agriculture and ecosystem stability worldwide. The chemical fertilizers used in the agriculture to increase yields, kill pathogens, pests, and weeds, have a big harmful impact on the ecosystem. Because of current public concerns about the side effects of agrochemicals, there is an increasing interest in improving the understanding of cooperative activities among plants and rhizosphere microbial populations. So, there is an urgent need of biological agents is accepted worldwide. The use of plant growth promoting Rhizobacteria (PGPR) is a better alternative to solve this problem. They play an important role to increase in soil fertility, plant growth promotion, and suppression of phytopathogens for development of ecofriendly sustainable agriculture. This review provides environment friendly approach to increase crop production and health, development of sustainable agriculture and commercialization by using of plant growth promoting rhizobacteria with global applicability.

ABSTRAKKegiatan pertambangan nikel menyisakan dampak pencemaran logam berat baik pada tanah maupun badan air. Salah satu metode yang banyak diaplikasikan untuk mengurangi cemaran logam berat adalah bioremediasi. Pemilihan bakteri yang berpotensi mengurangi kontaminasi logam berat di tanah sangat penting dalam proses bioremediasi. Langkah awal untuk memilih bakteri potensial adalah dengan melakukan identifikasi bakteri. Penelitian ini bertujuan untuk mengidentifikasi bakteri yang ada pada air kolam bekas galian di lahan bekas tambang nikel di Halmahera Timur. Metode yang digunakan dalam penelitian ini adalah isolasi dan identifikasi bakteri dengan metode konvensional meliputi uji morfologi, fisiologis, dan biokimia. Isolat bakteri diidentifikasi menggunakan Bergey's Manual Determinative. Hasil penelitian menunjukkan terdapat 6 genus bakteri yaitu Bacillus sp., Esherichia, Enterococcus, Pseudomona,s Staphylococcus, dan Klebsiella dengan 18 spesies bakteri pada air di lahan pasca tambang nikel. Secara morfologis didominasi oleh genus bakteri Bacillus sebesar 50 %. Hasil identifikasi bakteri ini membuktikan adanya bakteri indegenus yang resisten terhadap cekaman logam berat. Kata kunci: bakteri, tanah, air, kontaminasi, pasca tambang, Halmahera Timur ABSTRACT Nickel mining impact in heavy metal pollution on both soil and water. A method that is widely applied to reduce heavy metal contamination is bioremediation. Selection of bacteria that have potential reduction of heavy metal contamination in soil is very important in bioremediation process. The first step to select the potential bacteria is identification of samples. The purpose of this study is to identify existings bacteria in pond after

“…Previously S. arlettae isolates exhibiting growth over a 0.06-4.5 M NaCl have been reported by other researchers [17,18]. The applications of these isolates have been demonstrated in treatment of azo dye containing textile effluents [19], bioremediation of hexavalent chromium containing wastewaters [20,21] and as plant growth promoting bacteria [21,22].…”

An extremely halotolerant bacterium designated as HPSSN35C was isolated from saline soil of Dwarka beach, India. It exhibited growth over a wide range of NaCl in medium varying from 0 to 6 M. The isolate produced peach-pink pigment above ∼1.3 M NaCl. The culture was characterized using biochemical tests, bioMerieux Staph identification kit, API ID32 Staph system, and Biolog. Due to slow growth and extreme salt tolerance no ID was obtained in Biolog. Antibiotic sensitivity to various antibiotics was tested. Phenotypic characterization showed that it belonged to the novobiocin resistant staphylococci group. Analysis of 16S rRNA gene sequence comparison of 1452 base pairs showed that isolate is closely related to Staphylococcus saprophyticus group with close relationship to Staphylococcus arlettae (99% similarity). The halotolerant S. arlettae described in literature till date have been reported to tolerate 4.5 M NaCl and produce white to yellow pigment. The present study reports for the first time extremely halotolerant S. arlettae exhibiting growth up to ∼6 M NaCl and producing peach-pink pigment above ∼1.3 M NaCl.
