Effective Microorganism

Increasing urbanization and population concentrations are causing environmental problems such as soil and water pollution. In this study, we were present isolation and identification of Streptomyces sp and Rhodobacteria sp. Those effective microorganisms isolated from the wastewater and soil sample of Anand-Khujirt spring resort located in Khujirt soum, Uvurkhangai province in Mongolia. Based on morphological, cultural, and molecular characteristics (16S rDNA sequencing), those strain were identified as Rhodobacter sphaeroides (99% similarity) and Streptomyces cf.griseus (99% similarity). Rhodobacter sphaeroides could be used to reduce heavy metal contamination from soil. Furthermore, Streptomyces cf.griseus is an effective  microorganism, which produces 32 types of biologically active compounds for pharmaceutical or agricultural purposes.

Unique Species

The purpose of this study was to investigate streptomycete populations in desert and savanna ecozones in Sudan and to identify species based on 16S rRNA gene sequences. A total of 49 different Streptomyces phenotypes (22 from sites representing the desert and semi-desert ecozone; 27 representing the savanna ecozone) have been included in the study. The isolates were characterized phenotypically and confirmed using 16S rRNA gene sequence analysis. The two ecozones showed both similarities and uniqueness in the types of isolates. The shared species were in cluster 1 (Streptomyces (S.) werraensis), cluster 2 (Streptomyces sp.), cluster 3 (S. griseomycini-like), and cluster 7 (S. rochei). The desert ecozone revealed unique species in cluster 9 (Streptomyces sp.) and cluster 10 (S. griseomycini). Whereas, the savanna ecozone revealed unique species in cluster 4 (Streptomyces sp.), cluster 5 (S. albogriseolus/ S. griseoincarnatus), cluster 6 (S. djakartensis), and cluster 8 (Streptomyces sp.). Streptomycetes are widely distributed in both desert and the savanna ecozones and many of these require full descriptions. Extending knowledge on Streptomyces communities and their dynamics in different ecological zones and their potential antibiotic production is needed.

Streptomyces merupakan bakteri dari kelompok Actinomycetes. Genus ini diketahui dapat memproduksi berbagai senyawa aktif diantaranya antibiotik, antiviral, dan enzim. Enzim yang dapat ditemukan pada bakteri dan jamur yaitu salah satunya enzim kitinase. Enzim kitinase yang diproduksi oleh bakteri lebih baik dibandingkan kitinase dari sumber lain karena dengan waktu yang relatif singkat dapat melakukan proses perkembangbiakan. Bakteri kitinolitik merupakan agen pengendalian hayati terhadap jamur patogen maupun serangga hama yang sangat potensial karena aktivitas kitinase yang dimiliki. Penelitian ini bertujuan untuk mengisolasi, mengetahui karakteristik Streptomyces spp. dari lumpur selokan dan uji aktivitas enzim kitinase. Aktivitas enzim kitinase diketahui melalui zona bening yang terbentuk pada media uji. Hasil penelitian diperoleh lima spesies Streptomyces spp. dari  sampel lumpur selokan yang diisolasi dengan karakteristik yang berbeda-beda. Hasil penelitian juga menunjukkan bahwa dari lima spesies Streptomyces spp., dua spesies yaitu Streptomyces sp.3 dan Streptomyces sp.5 mampu memproduksi enzim kitinase, sementara tiga spesies Streptomyces lainnya tidak memproduksi enzim kitinase.  Streptomyces sp.3 memproduksi enzim kitinase dengan terbentuknya zona bening sebesar 1,85±0,07 cm dan pada Streptomyces sp.5 terbentuk zona bening sebesar 0,65 ±0,14 cm . Berdasarkan data tersebut Streptomyces sp.3 dan Streptomyces sp.5 memiliki potensi sebagai bakteri kitinolitik yang memiliki manfaat sebagai agen pengendalian hayati.

Polyurethane Degradation

Plastic wastes decomposition has been a pressing environmental problem worldwide. In this study, polyurethane (PUR), a thermoset plastic was tested for biodegradation by polyurethane-degrading microorganisms that were isolated from a dumpsite at Kamishihoro, Tokachi, Obihiro, Japan. Actinomycetes were the most abundant microorganisms from soil samples. From the 65 isolated microbial species, 16 possessed polyurethane-degrading ability. These isolates exhibited clearing zones on Yeast-extract salts + Agar and gelatin with polyurethane (YES-AG + PUR). The PUR-degrading isolates were characterized and identified based on their DNA sequence patterns. Some isolates belong to the same genus or species. They were Bacillus chitinolyticus (B03, B04, B07), Streptomyces spp. (B13, B19, C13a, C15, C17a, C17b), Pseudomonas sp. (B20), Bacillus pumilus(B21), Streptomyces cuspidosporus (C10b, C18, C19) and Pseudallesscheria baydii (F04, F07). Streptomyces sp. coded as C13a, with base sequence homology of 99.7% with Streptomyces albogriseolus, was believed to produce the highest amount of both exo- and endo polyurethanases. This was demonstrated by the widest clearing zones when broth and cell-bound supernatants were inoculated into the YES-AG + PUR plate.
