Salah satu sumber pencemar yang cukup dominan di lingkungan perairan pantai adalah pencemaran akibat limbah domestik. Selama ini yang dipakai untuk mengetahui pencemaran lingkungan oleh limbah domestik adalah menggunakan indikator biologi yaitu bakteri coliform. Namun penggunaan bakteri coliform sebagai indikator pencemaran limbah domestik mempunyai permasalahan antara lain tidak terdeteksinya bakteri coliform tersebut pada perairan pantai, sementara diduga kuat bahwa perairan tersebut tercemar oleh limbah domestik termasuk feces. Oleh karena itu indikator alternatif sangat diperlukan. Salah satu indikator alternatif pencemaran limbah domestik adalah koprostanol, yang mempunyai sifat cukup konservatif, dapat dikuntitatifkan dan dapat dihubungkan dengan sumber pencemar yang spesifik. Namun perlu diingat bahwa di alam, koprostanol mengalami proses degradasi oleh bakteri, sehingga perlu dilakukan penelitian mengenai isolasi dan identifikasi bakteri pendegradasi koprostanol pada lingkungan sungai, muara, dan perairan pantai Banjir Kanal Timur Semarang pada monsun timur. Penelitian dilakukan pada bulan Juli s/d Agustus 2003 pada lingkungan sungai, muara, dan perairan pantai Banjir Kanal Timur Semarang. Isolasi bakteri dari sampel air dan sedimen dilakukan di Laboratorium Mikrobiogenetika, FMIPA Jurusan Biologi UNDIP Semarang dan identifikasi bakteri pendegradasi koprostanol terseleksi dilakukan di Laboratorium Hama dan Penyakit Balai Besar Pengembangan Budidaya Air Payau (BBPBAP) Jepara. Hasil penelitian diperoleh bahwa bakteri pendegradasi koprostanol yang berasal dari lokasi Banjir Kanal Timur Semarang pada berbagai variasi lingkungan dan habitat diperoleh 69 isolat (83,13%) dari 83 isolat yang diuji. Sedangkan hasil identifikasi terhadap 6 isolat terbaik diperoleh 3 (tiga) genus bakteri mampu mendegradasi koprostanol, yaitu Achromobacter, Bacillus, dan Branhamella. Dari 3 genus bakteri pendegradasi koprostanol yang didapatkan, ada 2 (dua) genus yang selama ini belum dilaporkan, yaitu genus Achromobacter, dan Branhamella.

One of dominant sources in coastal waters is contamination by domestic wastes. So far to determine environmental contamination by domestic waste is by using biological indicator, coliform bacteria. However the use of coliform bacteria have problems for example, they cannot be detected in coastal waters contaminated by domestic waste including faeces. Therefore, an indicator alternative is urgently needed. Alternative indicator of domestic waste contamination is coprostanol, which is conservative, easy to quantity and related to specific pollutant source. It is important to note coprostanol is naturally degraded by indigenous bacteria. Therefore it is necessary to conduct a study on isolation and identification of coprostanol-degrading bacteria in river, estuarine, and coastal environments of Banjir Kanal Timur Semarang during dry season. The research had been carried out from July to August 2003 at environmental of river, estuarine, and coastal of Banjir Kanal Timur Semarang. Isolation of bacteria from water and sediment samples were conducted at Microbiogenetics Laboratory, Faculty of Mathematics and Natural Sciences Diponegoro University, meanwhile identificaton of coprostanol-degrading bacteria selected was conducted by at Pest and Diseases Laboratory, Balai Besar Pengembangan Budidaya Air Payau (BBPBAP) Jepara. The result showed that coprostanol-degrading bacteria obtained from Banjir Kanal Timur Semarang at various environments and habitat were 69 bacterial isolates (83,13%) from 83 isolat tested. Identification revealed that (three) genus were found to degrade coprostanol, namely Achromobacter, Bacillus, and Branhamella.
