The prokaryotes are by far the most abundant organisms inhabiting planet Earth. They are also by far the most diverse, both metabolically and phylogenetically; they encompass the Bacteria and the Archaea, two out of the three major divisions of living organisms. The current prokaryote species classification is based on a combination of genomic and phenotypic properties. The recommended cut-off value of 70% DNA-DNA similarity to delineate species signifies an extremely broad species definition for the prokaryotes compared with the higher eukaryotes. The number of validly named species of prokaryotes is currently slightly more than 6200. However, on the basis of small-subunit rDNA characterization of whole communities and other approaches, the more exact number of species present can be inferred to be at least two orders of magnitude larger. Classic culturing methods based on colony formation on agar are generally unsatisfactory for the recovery of bacteria from the environment. Many of the most abundant prokaryotes in nature have not yet been brought into culture. Some of these may thrive by means of as yet unknown modes of energy generation. Several novel methods have recently enabled the isolation of some interesting organisms of environmental significance. A better coverage of the prokaryote diversity on Earth depends on such innovative approaches, combined with appropriate funding.

Lichens are commonly described as a mutualistic symbiosis between fungi and “algae ” (Chlorophyta or Cyanobac-teria); however, they also have internal bacterial communities. Recent research suggests that lichen-associated microbes are an integral component of lichen thalli and that the classical view of this symbiotic relationship should be expanded to include bacteria. However, we still have a limited understanding of the phylogenetic structure of these communities and their variability across lichen species. To address these knowledge gaps, we used bar-coded pyrosequencing to survey the bacterial communities associated with lichens. Bacterial sequences obtained from four lichen species at multiple locations on rock outcrops suggested that each lichen species harbored a distinct community and that all communities were dominated by Alphaproteobacteria. Across all samples, we recovered numerous bacterial phylotypes that were closely related to sequences isolated from lichens in prior investigations, including those from a lichen-associated Rhizobiales lineage (LAR1; putative N2 fixers). LAR1-related phylotypes were relatively abundant and were found in all four lichen species, and many sequences closely related to other known N2 fixers (e.g., Azospirillum, Bradyrhizobium, and Frankia) were recovered. Our findings confirm the presence of highly structured bacterial communities within lichens and provide additional evidence that these bacteria may serve distinct functional roles within lichen symbioses.

The fruit fly Drosophila is a classic model organism to study adaptation as well as the relationship between genetic variation and phenotypes. Although associated bacterial communities might be important for many aspects of Drosophila biology, knowledge about their diversity, composition, and factors shaping them is limited. We used 454-based sequencing of a variable region of the bacterial 16S ribosomal RNA gene to characterize the bacterial communities associated with wild and laboratory Drosophila isolates. In order to specifically investigate effects of food source and host species on bacterial communities, we analyzed samples from wild Drosophila melanogaster and D. simulans collected from a variety of natural substrates, as well as from adults and larvae of nine laboratory-reared Drosophila species. We find no evidence for host species effects in lab-reared flies; instead, lab of origin and stochastic effects, which could influence studies of Drosophila phenotypes, are pronounced. In contrast, the natural Drosophila–associated microbiota appears to be predominantly shaped by food substrate with an additional but smaller effect of host species identity. We identify a core member of this natural microbiota that belongs to the genus Gluconobacter and is common to all wild-caught flies in this study, but absent from the laboratory. This makes it a strong candidate for being part of what could be a natural D. melanogaster and D.

It is difficult to genetically manipulate the medically and biotechnologically important genus Clostridium due to the existence of the restriction and modification (RM) systems. We identified and engineered the RM system of a model clostridial species, C. acetobutylicum, with the aim to allow the host to accept the unmethylated DNA efficiently. A gene CAC1502 putatively encoding the type II restriction endonuclease Cac824I was identified from the genome of C. acetobutylicum DSM1731, and disrupted using the ClosTron system based on group II intron insertion. The resulting strain SMB009 lost the type II restriction endonuclease activity, and can be transformed with unmethylated DNA as efficiently as with methylated DNA. The strategy reported here makes it easy to genetically modify the clostridial species using unmethylated DNA, which will help to advance the understanding of the clostridial physiology from the molecular level.

16S rRNA-based stable isotope probing identified active xylose- and glucose-fermenting Bacteria and active Archaea, including methanogens, in anoxic slurries of material obtained from a moderately acidic, CH4-emitting fen. Xylose and glucose were converted to fatty acids, CO2, H2, and CH4 under moderately acidic, anoxic conditions, indicating that the fen harbors moderately acid-tolerant xylose- and glucose-using fermen-ters, as well as moderately acid-tolerant methanogens. Organisms of the families Acidaminococcaceae, Aero-monadaceae, Clostridiaceae, Enterobacteriaceae, and Pseudomonadaceae and the order Actinomycetales, including hitherto unknown organisms, utilized xylose- or glucose-derived carbon, suggesting that highly diverse facul-tative aerobes and obligate anaerobes contribute to the flow of carbon in the fen under anoxic conditions. Uncultured Euryarchaeota (i.e., Methanosarcinaceae and Methanobacteriaceae) and Crenarchaeota species were identified by 16S rRNA analysis of anoxic slurries, demonstrating that the acidic fen harbors novel methano-gens and Crenarchaeota organisms capable of anaerobiosis. Fermentation-derived molecules are conceived to be the primary drivers of methanogenesis when electron acceptors other than CO2 are absent, and the collective findings of this study indicate that fen soils harbor diverse, acid-tolerant, and novel xylose-utilizing as well as glucose-utilizing facultative aerobes and obligate anaerobes that form trophic links to novel moderately acid-tolerant methanogens.

We have developed sediment-free anaerobic enrichment cultures that dechlorinate a broad spectrum of highly chlorinated polychlorinated biphenyls (PCBs). The cultures were developed from Aroclor 1260-contam-inated sediment from the Housatonic River in Lenox, MA. Sediment slurries were primed with 2,6-dibromo-biphenyl to stimulate Process N dechlorination (primarily meta dechlorination), and sediment was gradually removed by successive transfers (10%) to minimal medium. The cultures grow on pyruvate, butyrate, or acetate plus H2. Gas chromatography-electron capture detector analysis demonstrated that the cultures extensively dechlorinate 50 to 500 g/ml of Aroclor 1260 at 22 to 24°C by Dechlorination Process N. Triplicate cultures of the eighth transfer without sediment dechlorinated 76 % of the hexa- through nonachlorobiphenyls in Aroclor 1260 (250 g/ml) to tri- through pentachlorobiphenyls in 110 days. At least 64 PCB congeners, all of which are chlorinated on both rings and 47 of which have six or more chlorines, were substrates for this dechlorination. To characterize the bacterial diversity in the enrichments, we used eubacterial primers to amplify and clone 16S rRNA genes from DNA extracted from cultures grown on acetate plus H2. Restriction fragment length polymorphism analysis of 107 clones demonstrated the presence of Thauera-like Betaproteobacteria, Geobacter-like Deltaproteobacteria, Pseudomonas species, various Clostridiales, Bacteroidetes, Dehalococcoides of the Chlo-roflexi group, and unclassified Eubacteria.

The bacterial flagellum is important for motility and adaptation to environmental niches. The sequence of events required for the synthesis of the flagellar apparatus has been extensively studied, yet the events that dictate where the flagellum is placed at the onset of flagellar biosynthesis remain largely unknown. We addressed this question for alphaproteobacteria by using the polarly flagellated alphaproteobacterium Cau-lobacter crescentus as an experimental model system. To identify candidates for a role in flagellar placement, we searched all available alphaproteobacterial genomes for genes of unknown function that cluster with early flagellar genes and that are present in polarly flagellated alphaproteobacteria while being absent in alpha-proteobacteria with other flagellation patterns. From this in silico screen, we identified pflI. Loss of PflI function in C. crescentus results in an abnormally high frequency of cells with a randomly placed flagellum, while other aspects of cell polarization remain normal. In a wild-type background, a fusion of green fluorescent protein (GFP) and PflI localizes to the pole where the flagellum develops. This polar localization is indepen-dent of the flagellar protein FliF, whose oligomerization into the MS ring is thought to define the site of flagellar synthesis, suggesting that PflI acts before or independently of this event. Overproduction of PflI-GFP often leads to ectopic localization at the wrong, stalked pole. This is accompanied by a high frequency of flagellum formation at this ectopic site, suggesting that the location of PflI is a sufficient marker for a site for

Abstract.-A cellulose degrading bacterium, identified as Bacillus megaterium S3 on the basis of biochemical and 16S rRNA ribotyping, was isolated from vegetable market, Lahore, Pakistan. It was screened by efficiently growing on carboxymethyl cellulose (CMC-Na), Congo red agar, and minimal salt medium containing filter paper. The most suitable temperature for the growth of B. megaterium S3 was found to be 45ºC while the optimum growth pH was 7. B. megaterium S3 had a lag phase of 4 hours in LB medium while this phase prolonged to 6 hours in CMCNa medium. B. megaterium S3 had shown maximum enzyme activity in extra-cellular assay (75%) as compared to intra-cellular assay (17%). The optimum temperature and pH for the crude enzyme activity were found to be 50ºC and 8, respectively. Maximum crude enzyme extract (cellulase) activity was found in the presence of Zn ions. This alkalithermophilic enzyme from B. megaterium S3 can be exploited for biotechnological and industrial applications.
