How can I detect Nitrite in meat
In Europe many meat products like ham and smoked pork chop are cured. Curing is a process to preserve meat and sausages by addition of common salt. The meat develops a typical curing taste and becomes red in color. This process is important to avoid a grey coloration and a growth of microorganisms. However the reaction of nitrite with amino acids, can cause the formation of carcinogenic ...

Application of library-independent microbial source tracking methods for identifying the sources of faecal contamination in coastal areas
Faecal contamination sources were identified in coastal areas around the Guerande-Atlantique peninsula using two microbial source tracking (MST) methods: (i) Bacteroidales host-specific 16S rRNA gene markers measured by real-time PCR and (ii) F-specific bacteriophage (FRNAPH) genotyping. Both methods were used on 63 water samples from 7 water courses. HF183 marker and bacteriophage genogroup II ...

New PCR Primers for the Screening of NRPS and PKS-I Systems in Actinomycetes: Detection and Distribution of These Biosynthetic Gene Sequences in Major Taxonomic Groups
Nonribosomal peptide synthetases (NRPS) and type I polyketide synthases (PKS-I) are biosynthetic systems involved in the synthesis of a large number of important biologically active compounds produced by microorganisms, among others by actinomycetes. In order to assess the occurrence of these biosynthetic systems in this metabolically active bacterial group, we designed new PCR primers targeted ...

Bioavailability of pharmaceuticals in waters close to wastewater treatment plants: Use of fish bile for exposure assessment
Pharmaceuticals are ubiquitous in surface waters as a consequence of discharges from municipal wastewater treatment plants. However, few studies have assessed the bioavailability of pharmaceuticals to fish in natural waters. In the present study, passive samplers and rainbow trout were experimentally deployed next to three municipal wastewater treatment plants in Finland to evaluate the degree of ...

Why does the market need a new Phosgene indicator badge?
Usage of Phosgene Phosgene (COCl2) is a non combustible but very toxic gas. It is a raw material for plastics like Polycarbonates (i. e. Macrolon) or Polyurethanes. Monitoring of Phosgene Plants using or manufacturing Phosgene of course underlay strict safety regulations. Therefore they are equipped with portable and fixed gas detectors for Phosgene. While portable instruments are mostly used ...

Oligonucleotide-based fluorescence system for sensitive and selective detection of Ag(I) ions in aqueous solution
In this letter, a new homogeneous assay with high sensitivity and selectivity was developed for the detection of silver ions in aqueous media at room temperature by using EvaGreen (EG), polycytosine oligonucleotide C20 and single-walled carbon nanotubes (SWNTs). The fluorescence of EG is weak in the absence or presence of randomly coiled C20. After C20 interacted specifically with Ag+ ions ...

Adenovirus, MS2 and PhiX174 interactions with drinking water biofilms developed on PVC, cement and cast iron
Biofilms colonizing pipe surfaces of drinking water distribution systems could provide habitat and shelter for pathogenic viruses present in the water phase. This study aims (i) to develop a method to detect viral particles present in a drinking water biofilm and (ii) to study viral interactions with drinking water biofilms. A pilot scale system was used to develop drinking water biofilms on 3 ...

Analysis of Anionic Contamination & General Quality Testing in Water from Sewage Treatment Plants and Industrial Discharge & Effluents by Colorimetry
Problem The high concentration of Industry, Agriculture and People in and around the United States has changed the “nature” of our environment. There are Toxic Metals coming from various metallurgical processes; Plating, Foundry, Smelting, Milling, etc., which are readily determined by Atomic Absorption Spectroscopy (AAS). Volatile Organics from the many Petrochemical-based operations are ...

Data Collection for Smart LDAR - Optical Imaging
Abstract: Use of infrared cameras to discover gaseous VOCs as part of a Fugitive Emissions Leak Detection And Repair (LDAR) regulatory compliance program is new to the chemical processing and oil refining industry. When performing inspections using optical imaging cameras, there is a need for compliance record keeping. The person using an optical imaging camera to find leaks must also ...

IDEAL Lagoon Based Extended Aeration System with Batch Reactor Process Doubles Treatment Capacity at Grantsville WWTP
Originally designed for a 0.75 MGD capacity, the Grantsville Wastewater Treatment Plant receives residential wastewater from almost 10,000 residents in Grantsville, Utah, just west of Salt Lake City. In 2009, the plant was having significant trouble meeting the city’s discharge requirements for ammonia, TSS, and BOD. According to Ron Griffin, the plant’s operator, treated wastewater ...

Ultra-Pure Proof with Mass Detection
Before joining the newly formed Reach Separations in February 2012, I spent five years at AstraZeneca in analysis and purification (latterly as group lead in reversed phase and chiral purification). This experience gives me a good perspective of both the needs of “big pharma” and, more recently, the needs of a specialist separation solution provider. My time at AstraZeneca allowed me ...
