Copper pollution in the East Coast of Surabaya is one of the serious cases of heavy metal pollution in Indonesia. Pollution at this location has been proven to result in fish deaths and brain damage of local residents because they consume too much copper-contaminated fish. Copper bioremediation using indigen bacteria isolated from polluted environments is a promising solution to overcome copper pollution problems. Bacteria that commonly live in polluted environments can be isolated and used as copper bioremediation agents. This study aims to do: 1) isolation and characterization of copper resistant bacteria from the East Coast of Surabaya, 2) resistance testing of bacterial isolates, and 3) copper accumulation and biosorbtion tests of bacterial isolates. The bacterial isolates were characterized by the morphology of the colonies and their cells based on Gram staining. Resistance testing is done by determining Minimum Inhibitory Concentration/MIC. The accumulation test is carried out by separating the cell and growth medium, then each of them is distructed using HNO3. The results of isolation and characterization obtained six isolates of copper-resistant bacteria, namely PmbC1, PmbC2, PmbC3, PmbC4, PmbC5, and PmbC6 with MIC = 3 mM - 5mM CuSO4. PmbC4 isolate is the most resistant bacteria with the MIC of 5 mM and is capable of accumulating copper of 6.25 mg per gram of cell dry weight and biosorbtion of 92.17%.

Drought is a threat that affects plant growth and development. Wheat crops are very sensitive to heat and drought stress during flowering and grain development, which negatively affects grain yield and quality. Wheat with drought tolerant properties is a genetically modified plant obtained by inserting a cold shock protein gene from Escherichia coli so that it can increase the ability of wheat to adapt to drought. This literature review aims to provide information about the role of cold shock protein gene insertion from Escherichia coli in wheat plants to produce drought tolerant traits. The results of the literature review showed that the CspA gene from Escherichia coli inserted into DNA could increase gene expression by changing the nucleotides in the DNA sequence to increase G+C. Gene insertion produces recombinant DNA with specific nucleotide changes. Nucleotide changes were carried out to increase the overall G+C amino acid content without changing the existing CspA and CspB protein sequences. These changes played an important role in helping wheat adapt to drought. The leaves on the transgenic wheat showed a decrease in the rate of water loss because the stomata in these plants closed faster than in the ordinary wheat so that the transgenic wheat became more drought tolerant.

Osteoporosis merupakan penyakit metabolik tulang yang ditandai dengan menurunnya massa tulang akibat berkurangnya matriks dan mineral tulang disertai dengan kerusakan mikroarsitektur dari jaringan tulang. Osteoporosis dapat terjadi akibat berbagai faktor terutama faktor usia. Osteroporosis tidak menunjukan gejala yang jelas sehingga penderita osteoporosis beru menyadarinya ketika sudah terjadi fraktur pada tukang belakang yang menyebabkan nyeri. Tujuan penulisan ini adalah untuk mengetahui teknologi vertebroplasty dalam menangani fraktur kompresi tulang belakang manusia akibat penyakit osteoporosis. Kajian literatur ini akan membahas empat fokus kajian yaitu: 1) struktur dan fungsi sistem tulang, 2) kelainan struktur dan fungsi sistem tulang, 3) mekanisme terjadinya osteoporosis, serta 4) penanganan osteoporosis dengan menggunakan teknologi vertebroplasty. Pada dasarnya bagian luar tulang sangat kuat dan kokoh, tetapi pada bagian lainnya terdapat beberapa spons. Struktur tulang sangat mendukung setiap fungsi yang dimiliki. Pada keadaan normal, siklus pembentukan tulang yang melibatkan sel-sel tulang dan jaringan tulang akan membuat tulang tetap kuat. Ketidakseimbangan dalam regenerasi tulang di mana jaringan tulang trabekular lebih aktif dan cepat sementara tulang kortikal bekerja lebih lambat, dapat menjadi penyebab osteoporosis. Percutaneous vertebroplasty (PV) merupakan penanganan osteoporosis dengan injeksi langsung semen medis (polymethylmethacrylate [PMMA]) pada tulang yang keropos maupun retak, dapat meredakan nyeri dengan lebih cepat.

Copper resistant bacteria can be isolated from environments where copper levels are abundant from mining, industrial, or agricultural activities. The aim of this work was to study the molecular and physiologicalcharacteristics of indigenous copper resistant bacteria isolated from activated sludge in an industrial wastewatertreatment plant in Surabaya, Indonesia. The bacterial isolates were designated as strains IrC1, IrC2, and IrC4. Phylogenetic analysis based on 16S rDNA sequence analysis identified isolates IrC1, IrC2, and IrC4 as Acinetobacter oleivorans (98.41% similarity), Acinetobacter pitii (97.22% similarity), and Cupriavidus pauculus (96.99 similarity), respectively. The addition of 5 mM of CuSO4 in the medium affected morphological 4 appearance of all isolates to green and undulate margin might be due to the survival mechanism of bacteria by absorbing the copper. This studies indicated that copper resistance mechanism of all isolates was facilitated through the bioaccumulation of copper inside the cell, especially on the membrane fraction and inside the cytoplasm, albeit at a limited amount. It was observed that isolates IrC1, IrC2, and IrC4 were capable of accumulating 137.23 , 364.66 , and 272.07 mg L-1 of copper, respectively from the medium containing 8 mM CuSO4. The capability of isolates IrC1, IrC2, and IrC4 to accumulate copper can be exploited in bioremediation 4 process for removing copper from industrial sewage.
