Source tracking aerosols released from land-applied class B biosolids during high-wind events. (1/2)

DNA-based microbial source tracking (MST) methods were developed and used to specifically and sensitively track the unintended aerosolization of land-applied, anaerobically digested sewage sludge (biosolids) during high-wind events. Culture and phylogenetic analyses of bulk biosolids provided a basis for the development of three different MST methods. They included (i) culture- and 16S rRNA gene-based identification of Clostridium bifermentans, (ii) direct PCR amplification and sequencing of the 16S rRNA gene for an uncultured bacterium of the class Chloroflexi that is commonly present in anaerobically digested biosolids, and (iii) direct PCR amplification of a 16S rRNA gene of the phylum Euryarchaeota coupled with terminal restriction fragment length polymorphism to distinguish terminal fragments that are unique to biosolid-specific microorganisms. Each method was first validated with a broad group of bulk biosolids and soil samples to confirm the target's exclusive presence in biosolids and absence in soils. Positive responses were observed in 100% of bulk biosolid samples and in less than 11% of the bulk soils tested. Next, a sampling campaign was conducted in which all three methods were applied to aerosol samples taken upwind and downwind of fields that had recently been land applied with biosolids. When average wind speeds were greater than 5 m/s, source tracking results confirmed the presence of biosolids in 56% of the downwind samples versus 3% of the upwind samples. During these high-wind events, the biosolid concentration in downwind aerosols was between 0.1 and 2 microg/m3. The application of DNA-based source tracking to aerosol samples has confirmed that wind is a possible mechanism for the aerosolization and off-site transport of land-applied biosolids.  (+info)

First: Opinions will differ, but with obstetric care, you have open access to your obstetrician, usually for an unlimited number of visits. If you want reassurance of the babys heartbeat, id rather you come in to see me than make yourself nervous with a home monitor. If you do decide to get one, remember that finding the heartbeat, especially early on, is not necessarily easy. Dont go crazy.

Transcripts of cprA5 were not detected from strain PCP-1 cultured in the absence of CPs, but they were detected in the presence of 2,4,6-TCP or 3,5-DCP (an inducer of the meta- and para-dechlorinating activities) [40]. RT-qPCR revealed that cprA5 expression was strongly upregulated in the presence of 3,5-DCP in strain PCP-1 cultures [50]. For 2,4,6-TCP-amended cultures, the occurrence of 2,4-DCP was associated with the upregulation of cprA5 in strain PCP-1 cultures. Kim et al. [38] also observed this upregulation with the D. hafniense strain DCB-2 for rdhA3 (corresponding to cprA5) by microarrays. Upregulation of cprA5 occurred in cultures containing as little as 0.15 µM 3,5-DCP [50]. No upregulation was observed in PCP-amended cultures after 12 h (figure 4).. Significant upregulation of cprA4 was not observed in strain PCP-1 cultures amended with 2,4,6-TCP or 3,5-DCP. However, in PCP-amended cultures, we noticed a 13-fold increase in cprA4 transcript levels, which was just above the level of ...

Class A Biosolids is a designation for dewatered and heated sewage sludge that meets U.S. EPA guidelines for land application with no restrictions. Thus, class A biosolids can be legally used as fertilizer on farms, vegetable gardens, and can be sold to home gardeners as compost or fertilizer. Compared to Class B Biosolids, Class A Biosolids are virtually the same, but with stricter limits on pathogens and "vector attraction" (i.e. class A biosolids must not attract disease-carrying insects or rodents, etc). The EPA claims that Class A biosolids must "contain no detectible levels of pathogens"[1] but the only pathogens actually measured and regulated in the law are fecal coliform and salmonella.[2] Despite the U.S. EPAs assurances of safety,[3], the safety requirements for Class A Biosolids do nothing to regulate or limit the numerous other contaminants routinely found in sewage sludge.. ...

The first crystal structure of the vitamin B12-binding protein from a three-component O-demethylase enzyme system is reported. During O-demethylation methyl groups are transferred from phenyl methyl ethers to tetrahydrofolate via methyl-B12 intermediates. This study describes the identification and the structural and spectroscopic analysis of a cobalamin-binding protein (termed CobDH) implicated in O-demethylation by the organohalide-respiring bacterium Desulfitobacterium hafniense DCB-2. The 1.5 Å resolution crystal structure of CobDH is presented in the cobalamin-bound state and reveals that the protein is composed of an N-terminal helix-bundle domain and a C-terminal Rossmann-fold domain, with the cobalamin coordinated in the base-off/His-on conformation similar to other cobalamin-binding domains that catalyse methyl-transfer reactions. EPR spectroscopy of CobDH confirms cobalamin binding and reveals the presence of a cob(III)alamin superoxide, indicating binding of oxygen to the fully ...
Sulfur is an essential element for life and the metabolism of organic sulfur compounds plays an important role in the global sulfur cycle. Sulfur occurs in various oxidation states ranging from +6 in sulfate to -2 in sulfide (H2S). Sulfate reduction can occur in both an energy consuming assimilatory pathway and an energy producing dissimilatory pathway. The assimilatory pathway, which is found in a wide range of organisms, produces reduced sulfur compounds for the biosynthesis of S-containing amino acids and does not lead to direct excretion of sulfide. In the dissimilatory pathway, which is restricted to obligatory anaerobic bacterial and archaeal lineages, sulfate (or sulfur) is the terminal electron acceptor of the respiratory chain producing large quantities of inorganic sulfide. Both pathways start from the activation of sulfate by reaction with ATP to form adenylyl sulfate (APS). In the assimilatory pathway [MD:M00176] APS is converted to 3-phosphoadenylyl sulfate (PAPS) and then reduced ...
Homologous recombination (HR) is essential for the accurate repair of DNA double-strand breaks (DSBs), potentially lethal lesions. HR takes place in the late S-G2 phase of the cell cycle and involves the generation of a single-stranded region of DNA, followed by strand invasion, formation of a Holliday junction, DNA synthesis using the intact strand as a template, branch migration and resolution. It is investigated that RecA/Rad51 family proteins play a central role. The breast cancer susceptibility protein Brca2 and the RecQ helicase BLM (Bloom syndrome mutated) are tumor suppressors that maintain genome integrity, at least in part, through HR ...
