Removal of Disperse Red 60 dye from aqueous solution using free and composite fungal biomass of Lentinus concinnus
Lentinus concinnus biomass was immobilized to carboxyl derivative of cellulose, carboxymethyl cellulose (CMC), in the presence of FeCl3 (0.1 mol L−1) via ionic cross-linking. The beads containing immobilized fungal biomass were incubated at 30 °C for three days to permit growth of the fungus. The free and immobilized fungal biomass were tested for adsorption of Disperse Red 60 (DR-60) ...

Microbial reduction efficiencies of filtration, electrostatic polarization, and UV components of a Germicidal Air Cleaning System
Abstract: This study determined the effectiveness of components of a germicidal air-cleaning system involving filtration, electrostatic polarization, and UV light on the reduction of airborne bacteria and molds. The filter alone, filter and electrostatic polarization combined, and the filter, electrostatic polarization, and UV light were found to be effective (P < 0.05) in reducing a given ...

CO2 monitoring for Kerry Foods - Case Study
How the company operates The Kerry Foods plant processes food ingredients, such as fruit conserves and confectionery sauces, which are stored and distributed in 2000 tanks. Each tank is monitored regularly for patterns of CO2 build-up. Although CO2 levels may rise to above 1% with some foods, such as strawberry or peach, higher levels can give an early indication of a problem. This may be simply ...

Hurricane Sandy: More Damage than the Obvious
We all know that Hurricanes leave a wide swath of destruction in their wake. Many communities along the shoreline are devastated. Many, many homes are completely destroyed; only rubble remains. Many of the houses, apartment buildings and stores that survive the structural damage wrought by the storm face delayed damage. High winds drive water through cracks and crevices around door jambs and ...

Toxicity assessment of diesel and metal contaminated soils through elutriate and solid phase assays with the slime mould, Dictyostelium discoideum
A suite of organisms from different taxonomical and ecological positions are needed to assess environmentally relevant soil toxicity. We herein present a new bioassay based on Dictyostelium that is aimed at integrating slime moulds into such a testing framework. Toxicity tests on elutriates and the solid phase developmental cycle (DDDC) assay were successfully applied to a soil spiked with a ...

Purpose of Mold Sampling During An Inspection
As part of determining whether an indoor environment is contaminated with excessive amounts of mold and requires remediation, Indoor Environmental Technologies (IET) routinely performs air and surface mold sampling or testing. While there are many types of sampling methods, IET uses two of them the most: Air sampling using a “spore trap” sampler. Considerable information can be ...

Why a Mold Inspection before Remediation is Always a Good Idea
There are several important reasons why Indoor Environmental Technologies, Inc. (IET), and published industry standards, recommend that a mold inspection be performed by a separate company prior to starting mold remediation. In fact, many of the better remediation contractors in Florida will not start a remediation project without a mold protocol in hand. Consider the following four reasons: 1. ...

IAQ UPDATE: Using an Infrared Camera to Detect Water and Mold Problems
A low temperature range infrared camera is a very useful tool in detecting the presence of water or moisture that ultimately leads to mold growth. Infrared or thermal inspection does not directly identify the presence of mold, but it may be used to find moisture where mold may cultivate, especially behind wall board. But Beware! I have seen many cases where the infrared camera results have been ...
