摘要

水中沙门氏菌的感染会破坏养殖,降低渔获物的质量,损害体育产品的质量。需要进行研究,以克服和预防沙门氏菌在某些处理部门的活性。可以做出的努力之一是利用生活在地下水位结晶传统盐矿顶部的嗜盐细菌资源作为沙门氏菌的活性抑制剂。本研究旨在确定从传统盐矿Pamekasan Madura培养的极端嗜盐细菌作为沙门氏杆菌活性抑制剂的潜力。研究中使用的方法包括几个阶段,即分离、纯化、克染料测试和细菌抑制区测试。在CX43RF型双筒望远镜和MDCE-5C型数码相机下观察了极端嗜盐细菌的形态特征和克数聚集。针对沙门氏菌的极端嗜盐细菌分离物活性试验采用重叠法和扩散法进行抑制区试验。本研究结果表明,通过测量直径为4.28mm和2.45mm的屏障区,极端嗜盐细菌的分离株可以抑制沙门氏菌的活性。本研究结果有望成为开发极端嗜盐菌,特别是海洋药理学生物技术的初步信息。[UNK]水中的沙门氏菌可能对水产养殖有害,降低捕获渔业产品的质量,并损害加工渔业产品的品质。需要进行研究,以克服和预防沙门氏菌在一些渔业部门的活动。可以做的努力之一是利用大量生活在传统盐池结晶表水中的嗜盐细菌资源作为抑制这些细菌活性的试剂。本研究旨在确定从Pamekasan Madura传统盐池培养的极嗜盐细菌作为沙门氏菌活性抑制剂的潜力。本研究中使用的方法包括几个阶段,即分离、纯化、革兰氏染色试验和细菌抑制区试验。在具有MDCE-5C型数码相机的CX43RF双目显微镜下观察极端嗜盐细菌的形态特征和革兰氏分组。采用重叠法和扩散法对极嗜盐菌分离株进行了对沙门氏菌的活性测试。结果表明,极端嗜盐细菌分离株能够抑制沙门氏菌的活性,抑制区直径分别为4.28mm和2.45mm。这项研究的结果有望成为未来在生物技术领域,特别是海洋药理学领域开发极端嗜盐细菌的初步信息。

Potensi Bakteri Halofilik Ekstrim dari Tambak Garam Tradisional sebagai Penghambat Aktivitas Bakteri Salmonella sp.
Infeksi bakteri Salmonella sp. di perairan dapat merugikan perikanan budidaya, menurunkan kualitas hasil perikanan tangkap dan merusak kualitas produk olahan perikanan. Perlu dilakukan penelitian untuk mengatasi dan mencegah aktivitas bakteri Salmonella sp. pada beberapa sektor perikanan tersebut. Salah satu upaya yang bisa dilakukan adalah memanfaatkan sumberdaya bakteri halofilik yang hidup melimpah di air meja kristalisasi tambak garam tradisional sebagai agen penghambat aktivitas bakteri Salmonella sp.. Penelitian ini bertujuan untuk mengetahui potensi bakteri halofilik ekstrim yang dikultur dari tambak garam tradisional Pamekasan-Madura sebagai penghambat aktivitas bakteri Salmonella sp.. Metode yang digunakan dalam penelitian terdiri dari beberapa tahap yaitu isolasi, purifikasi, uji pewarnaan gram dan uji zona hambat bakteri. Karakteristik morfologi dan pengelompokan gram bakteri halofilik ekstrim diamati dibawah mikroskop binokuler model CX43RF dengan tipe kamera digital MDCE-5C. Uji aktivitas isolat bakteri halofilik ekstrim terhadap Salmonella sp. dilakukan dengan uji zona hambat menggunakan metode overlay dan difusi. Hasil penelitian diperoleh menunjukkan bahwa isolat bakteri halofilik esktrim mampu menghambat aktivitas Salmonella sp. dengan kisaran zona hambat berdiameter 4,28 mm dan 2,45 mm. Hasil penelitian ini diharapkan menjadi informasi awal untuk dipertimbangkan dalam pengembangan pemanfaatan bakteri halofilik ekstrim di bidang bioteknologi khususnya farmakologi laut kedepannya. Salmonella sp. in the waters can be detrimental to aquaculture, reduce the quality of captured fishery products and damage the quality of processed fishery products.

期刊介绍: The Journal of Marine Research publishes peer-reviewed research articles covering a broad array of topics in physical, biological and chemical oceanography. Articles that deal with processes, as well as those that report significant observations, are welcome. In the area of biology, studies involving coupling between ecological and physical processes are preferred over those that report systematics. Authors benefit from thorough reviews of their manuscripts, where an attempt is made to maximize clarity. The time between submission and publication is kept to a minimum; there is no page charge.
