Draft genome sequences of three filamentous cyanobacteria isolated from brackish habitats.

ABSTRACT: Brackish cyanobacterial genome sequences are relatively rare. Here, we report the 5.5 Mbp, 5.8 Mbp and 6.1 Mbp draft genomes of Spirulina sp. CCY15215, Leptolyngbya sp. CCY15150 and Halomicronema sp. CCY15110 isolated from coastal microbial mats on the North Sea beach of the island of Schiermonnikoog in the Netherlands. Large scale phylogenomic analyses reveal that Spirulina sp. CCY15215 is a large cell diameter cyanobacterium, whereas Leptolyngbya sp. CCY15150 and Halomicronema sp. CCY15110 are the first reported brackish genomes belonging to the LPP clade consisting primarily of Leptolyngbya, Plectonema and Phormidium spp. Further genome mining divulges that all new draft genomes contain, ggpS and ggpP , the genes responsible for synthesising glucosylglycerol (GG), a compatible solute found in moderately salt-tolerant cyanobacteria.

Draft genome sequences of three NDM-1-producing Enterobacteriaceae species isolated from Brazil.

Project description:The emergence of multidrug-resistant Enterobacteriaceae strains producing carbapenemases, such as NDM-1, has become a major public health issue due to a high dissemination capacity and limited treatment options. Here we describe the draft genome of three NDM-1-producing isolates: Providencia rettgeri (CCBH11880), Enterobacter hormaechei subsp. oharae (CCBH10892) and Klebsiella pneumoniae (CCBH13327), isolated in Brazil. Besides blaNDM-1, resistance genes to aminoglycosides [aadA1, aadA2, aac(6')-Ib-cr] and quinolones (qnrA1, qnrB4) were observed which contributed to the multidrug resistance profile. The element ISAba125 was found associated to the blaNDM-1 gene in all strains.

Phyllosilicates as protective habitats of filamentous cyanobacteria Leptolyngbya against ultraviolet radiation.

Project description:Phototrophic cyanobacteria are limited in growth locations by their need for visible light and must also cope with intermittent ultraviolet radiation (UVR), especially in extreme environments such as deserts and on early Earth. One survival method for cyanobacteria is growing endolithically within minerals such as micas, gypsum, and quartz minerals. However, the capability of different mica minerals to protect cyanobacteria from UVR, while at the same time allowing transmission of photosynthetically active radiation (PAR), has only been minimally examined. In this study, we performed laboratory incubation experiments to demonstrate that a model filamentous cyanobacterium, Leptolyngbya sp., can colonize micas, such as muscovite, phlogopite, and biotite. After inoculation experiments confirmed that these cyanobacteria grew between the sheets of mica, Leptolyngbya sp. colonies were exposed to UVB and UVC for up to 24 hrs, and the level of survival was determined using chlorophyll a and carotenoid assays. Of the three micas investigated, muscovite, being an Fe-poor and Al-rich mica, provided the least attenuation of UVR, however it transmitted the most visible light. Fe-rich biotite provided the best UVR shielding. Phlogopite, apparently because of its intermediate amount of Fe, showed the greatest ability to shield UVR while still transmitting an adequate amount of visible light, making it the ideal habitat for the cyanobacterium. Upon exposure to UVR, significant shifts in several important fatty acids of the cyanobacterium were detected such as linolenic acid and oleic acid, 18:3ω3 and 18:1ω9c, respectively. These cellular changes are interpreted to be a consequence of UVR and other accessory stress (such as O3).
