“…Seventy-four percent of QH bacterial clones and 89% of YPL bacterial clones had their greatest (87-100%) sequence identity with uncultured environmental clones. The diversity of novel phylogenetic groups in these salt mines is supported by previous work that yielded several novel bacterial isolates [21][22][23][24][25][26].…”

While much is known about the microbial diversity in some hypersaline environments, little is known about those of salt mine tunnel soils. The objective of this study was to conduct a comprehensive phylogenetic comparison of the archaeal and bacterial communities present in Yipinglang salt mine (YPL) and Qiaohou salt mine (QH) tunnels differing in salinity and salt composition using 16S rRNA gene clone libraries. Two hundred twenty-eight sequences for QH and 182 sequences for YPL were analyzed by amplified ribosomal DNA-restriction analysis. Libraries revealed 44 bacterial and 57 archaeal different operational taxonomic units belonging to at least 8 bacterial and 3 archaeal divisions, but not all divisions were observed in both salt mines. The bacterial community affiliated with the Bacteroidetes was the most abundant (60% of clones) in QH, while the community in YPL was dominated by δ-Proteobacteria (45% of clones). All archaeal clones from QH were affiliated with Halobacteriaceae. In contrast, in the YPL library, 49% of clones belonged to Halobacteriaceae, 31% of clones related to unclassified archaea, and 21% of clones belonged to Crenarchaeota. Bioinformatic analysis and comparisons showed that the clone libraries were significantly different between two salt mines.

“…Actinobacteria implicated in deterioration of art work are considered serious risk factors if environmental changes promote their massive proliferation (Groth et al, 1999b ; Portillo et al, 2009 ). To date, four new genera Beutenbergia, Fodinibacter, Hoyosella , and Knoellia have been reported from limestone habitats and related limestone ecosystems such as cave biofilms (Groth et al, 1999b , 2002 ; Jurado et al, 2009 ; Wang et al, 2009 ).…”

Studies on actinobacterial diversity in limestone habitats are scarce. This paper reports profiling of actinobacteria isolated from Hundung limestone samples in Manipur, India using ARDRA as the molecular tool for preliminary classification. A total of 137 actinobacteria were clustered into 31 phylotypic groups based on the ARDRA pattern generated and representative of each group was subjected to 16S rRNA gene sequencing. Generic diversity of the limestone isolates consisted of Streptomyces (15 phylotypic groups), Micromonospora (4), Amycolatopsis (3), Arthrobacter (3), Kitasatospora (2), Janibacter (1), Nocardia (1), Pseudonocardia (1) and Rhodococcus (1). Considering the antimicrobial potential of these actinobacteria, 19 showed antimicrobial activities against at least one of the bacterial and candidal test pathogens, while 45 exhibit biocontrol activities against at least one of the rice fungal pathogens. Out of the 137 actinobacterial isolates, 118 were found to have at least one of the three biosynthetic gene clusters (PKS-I, PKS-II, NRPS). The results indicate that 86% of the strains isolated from Hundung limestone deposit sites possessed biosynthetic gene clusters of which 40% exhibited antimicrobial activities. It can, therefore, be concluded that limestone habitat is a promising source for search of novel secondary metabolites.

“…It was earlier reported that actinomycetes can be isolated from limiting ecosystems including these hypogean environments and these microorganisms can be used for screening of valuable bioactive metabolites. In Northern Spain, Italy, Korea and China, the studies of the biodiversity of caves and mines have revealed that actinomycetes form an abundant taxonomic group (Wang et al, 2009). Hence, actinomycete genera like Fodinibacter, Beutenbergia, and Knoellia as have been isolated from these hypogean environments.…”

The appearance of new deadly diseases like cancer and the burgeoning problem of drug resistance among common bacteria l pathogens are a serious threat to a vailable trea tments. Since the channels of compounds under development are limited, this necessitates the discovery of new drugs. It is where actinomycetes can complement in the accomplishment of development of thera peu tically new bioactive compounds, predomina ntly u sed in antibiotic production. Actinomycetes are diverse in their location and have proven ability to produce new bioactive compounds. By employing modern microbiological and molecular technologies, the target-directed search for detection and isolation of bioactive actinomycetes is gaining more strength. Therefore, the innova tive isolation of actinomycetes from extreme ecosystems, their identification and cultivation using novel techniques are imperative to pursue for drug discovery.
