Abstract

Antifungi-producing rhizobacteria have been recognized playing an important role in plant disease suppression. In our laboratory, 13 indigenous soybeans' rhizobacteria Pseudomonas sp. that showed strong growth inhibition of root pathogenic fungi, Rhizoctonia solani, Fusarium oxysporum and Sclerotium rolfsii, have been isolated from rhizosphere of soybean plant. For further understanding, the genetic diversity of the antifungi-producing Pseudomonas sp. was investigated using Amplified 16S rDNA Restriction Analysis (ARDRA) and 16S rRNA gene sequences analysis. 16S rDNA were amplified by PCR technique and digested with restriction endonuclease HaeIII, RsaI and AluI. Sequences of 16S rRNA gene were analyzed using the BLAST program for similarity searches on sequence databases. ARDRA based dendrogram analysis was carried out by neighbor-joining of TREECON 1.3b software package. ARDRA indicated the variability of Pseudomonas sp. based on the digestion sites. Dendrogram clustering analysis based on the restriction enzymes profile of the amplified rDNA distinguished Pseudomonas sp. into 7 ribotype groups. The sequences of 16S rRNA gene confirmed that the isolates belonging to Pseudomonas sp. and the phylogenetic tree formed 4 clusters. There was a quite overlap among ARDRA groups and 16S rRNA sequence clusters. This finding suggested that antifungal producing Pseudomonas sp. were present in the rhizosphere of soybean plant and the level of genetic diversity exist within these species. Sequence analysis of the 16S rRNA gene of the Pseudomonas sp. with an identical ARDRA pattern confirmed that members of an ARDRA group were closely related to each other.

Abstract

The emerge of antibiotic resistance has been an important issue all over the world, on the other hand, infectious diseases have been one of the highest causes of death causes in the world. Therefore, the discovery of a new antimicrobial drug is very important, and the group of rare actinomycetes are really promising as the producer of new bioactive compounds, in this case antibiotics. In this study we screened and characterized the actinomycetes with antibacterial activity against Escherichia coli ATCC 35218 resistant beta-lactam antibiotics. A total of 96 strains collected in Biotechnology Microbial Culture Collection (BioMCC), BPPT, were screened for their antibacterial activities by the agar plug method. Three strains, at-HH-64, at-HH-78, and at-HH-259, showed antibacterial activity. The selected strains were cultured on four different media, both solid and liquid media, e.g. ISP2, ISP4, Micromonospora Starch Medium (MS), and Bennet’s Medium (BM), and we characterized their morphology and growth patterns. Morphological characterization showed that all strains belonged to the genera Micromonospora. The active strains were also identified based on 16S rRNA partial sequence. BLAST search of the 16S rRNA sequences of all tested strains with the sequences available in the NCBI data bank showed a maximum similarity 99% with Micromonospora chersina.

Abstract

Traditionally Curcuma zedoaria (white turmeric) known as herbal medicine which possessing many biological activities. Many endophytic bacteria live in association with their host and may play an important biological roles. The main interest of this study was to investigate the endophytic bacterial diversity associated with white turmeric. White turmerics were collected from three locations in Bogor, West Java, Indonesia. The isolation of endophytic bacteria was carried out using 4 kinds media (Nutrient Agar (NA), NA contained white turmeric extract (NAT), Water Yeast Extract Agar (WYEA), WYEA contained white turmeric extract (WYEAT)), and 2 methods of spread plate and plant piece methods. The identification of selected isolates was conducted by molecular analysis based on 16S DNA. The suitable media and method of isolation endophytic bacteria were NA and spread plate method. A total of 207 bacterial colonies were isolated from rhizomes, stems, and leaves and 73 endophytic bacteria were selected based on morphological characteristics. From them, 32% isolates from Bojong Gede, 22% isolates from Cibinong and 46% isolates from Dramaga were obtained. Endophytic bacteria were predominated 38% in the rhizomes, 32% of stems, and 30% of leaves. Based on 16S rDNA sequence analysis, the isolates were belonging to the cluster Alphaproteobacteria, Betaproteobacteria, Gammaproteobacteria, Firmicutes, and Actinobacteria, with twenty three different genera includes Stenothropomonas, Pseudomonas, Enterobacter, Providencia, Klebsiella, Dickeya, Pantoea, Bacillus, Acinetobacter, Citrobacter, Mycobacterium, Cellulomonas, Microbacterium, Methylobacterium, Penylobacterium, Roseomonas, Agrobacterium, Bosea, Xanthobacter, Rhizobium, Burkholderia, Ralstonia, and Alcaligenes. The plant location, age, part of plant, media and method of isolation seem to influence the endophytic bacterial communities.

Abstract

Actinomycetes are microorganisms that play important role to support human health and  known as soil microorganisms. The aim of the research was to describe genus diversity of actinomycetes in Cibinong Science Center (CSC), West Java. Samples for isolation were soil and plant litters. The samples were air dried and ground. We employed isolation methods: dry heat (DH), sodium dodecyl sulphates-yeast extract (SDS-YE), rehydration and centrifugation (RC), and oil separation (OS). A total of 263 isolates of actinomycetes were isolated in CSC, in 2004-2006. Totally 58, 144, 50, and 11 isolates were isolated under each isolation methods, respectively. All isolates were identified using the 16S rRNA gene sequencing method. The results showed that the isolates were belonged to the family Kineosporiaceae, Micromonosporaceae, Nocardiaceae, Pseudonocardiaceae, Streptomycetaceae, Streptosporangiaceae, Mycobacteriaceae, Nocardioidaceae, Nocardiopsaceae, and Thermomonosporaceae. There were 23 genera under those families. Homology value of the isolates based on BLAST search using 16S rRNA gene sequence data as queries showed that 136, 91, 30, and 6 isolates were ≥99, 98, 97, and ≤96%, respectively, compared to the known sequence in data base. The later 6 isolates were interesting for further identification leading to new taxa. Recognized species of Streptomyces genera under the member of the Streptomycetaceae were dominant among other isolates.

Abstract

Endophytic actinomycetes associated with medicinal plants is very important as source of various bioactive compounds. The fact that more than 99% of microbes that exist in nature may have the potency but still unexplored. Published data regarding diversity of endophytic actinomycetes from T. crispa is mainly based on a culturable approach. This paper describes the first reported data regarding metagenomic analysis on the diversity of endophytic actinomycetes from T.crispa based on 16S rRNA gene using PCR-DGGE. There were some similarities amongst endophytic actinomycetes found in stems, roots, and leaves with soil actinomycetes community in the rhizosphere of T. crispa. There were a total of 21 bands found from the DGGE analysis which were interpreted using Phoretix 1D software. Diversity of actinomycetes in the stems, leaves, roots were represented by 17, 16, and 14 bands, respectively. Whereas only 10 bands represented diversity of actinomycetes in the soil rhizosphere. The 12 dominant and or different bands with 180 bp in size were molecularly sequenced. The A4 and A9 bands have 95% and 86% similarities with Williamsia and Streptomyces, respectively. These similarities were less than 97% thus may indicate novel actinomycetes. The other 10 sequenced bands have closed similarity ranging from 97-100% and they were closely related to the genus Streptomyces, Microbacterium, Amycolatopsis, Actinomadura, Actinoplanes, Actinokineospora, Kibdelosporangium, Williamsia and Kocuria. These findings indicate that diversity of actinomycetes can be found associated with T. crispa.
