Screening and Characterization of Anoxigenic Photosynthetic Bacteria as Producer of Caroteniod Pigments From Palm Liquid Sewages

Abstract

Palm liquid sewage is organic waste that contains complex compounds such as water, oil, and organic solids. The organic content of palm liquid sewages is an indication of the abundance of microorganisms. This study aims to obtain anoxygenic photosynthetic bacteria (BFA) that produce carotenoid pigments from palm liquid sewages. Therefore, We isolated and screened of BFA from three palm liquid sewage disposal sites in Jambi Province. This research was conducted by an experimental method using a modified mineral medium. BFA isolates that growth and produced carotenoid pigments are visible because of the distribution of reddish-yellow pigments on the culture media. Screening results obtained 11 isolates of BFA sequentially Bg1K201, Bg1K202, Bg2k201, Bg3k201, Mr1k201, Mr1k202, Sl1k201, Sl1k202, Sl2k201, Sl2k202 and Sl3k202. The results of morphological and physiological characterization based on the Bergeys Manual of Determinative Bacteriology show that there are two types of BFA genera that have carotenoid pigments, respectively, the genus Rhodobacter (Bg1k201, Bg1k202, Bg3k201, Sl1k201, Sl1k202, and Sl1k202, and Sl2k202, and Sl1k202, and Sl2k202, and Sl1k202 and Sl2k202, and Sl2k202, and Sl2k202. Sl2k202, and) the genus Rhodopseudomonas (Bg2k201, Mr1k201 and Mr1k202)

Sosialisasi Pembuatan Bakteri Fotosintesis sebagai Penyubur Tanaman

“…Ini juga mengandung vitamin dan mineral seperti B1, B2, B5 dan B12, asam folat, vitamin C, vitamin D dan vitamin E. ( 5)penambahan suplemen atau nutrisi sehingga mampu mengurangi penggunaan pupuk kimia dan secara tidak langsung sangat ramah lingkungan dan bisa mengurangi biaya produksi hingga sampai 50%, (6) membantu menstimulasi pertumbuhan akar tanaman untuk berkembang dan bercabang dengan baik, sehingga menghasilkan jumlah serat yang baik, (7) membentu menstimulasi kekebalan tanaman seperti daun, bunga, buah dan kulit kayu sehingga lebih kuat terhadap serangan hama dan penyakit, dan (8) membantu akar, daun, bunga dan ranting tanaman tumbuh lebih cepat serta mampu mengurangi infeksi, jamur atau pathogen dan dapat mengendalian penyakit busuk akar. Manfaat lainnya untuk membantu mengurangi gas dan limbah ditempat penampungan hewan, menambah nutrisi sehingga mampu menambah berat badan ternak dan ikan serta membantu melindungan hewan dan ikan dari bakteri jahat [10].…”
