  • Multidrug resistance in fungi

    One of the major advances serving to define the beginning of the era of modern medicine was the development of penicillin in the early 1940s as the first widely used antibiotic effective against microorganisms (reviewed in reference 111). In what has become an all-too-common trend, antibiotic-resistant isolates emerged soon after the large-scale use of penicillin to treat bacterial infections ...

  • Awareness of Fungi on Wood is Critical to Professionals

    Untitled Document Those who deal with indoor fungal contamination could benefit by understanding more about the biology of common types of fungi on wood and wood products. It may assist in identifying potential ...

  • Novel diesel-oil-degrading bacteria and fungi from the Ecuadorian Amazon rainforest

    Isolating new diesel-oil-degrading microorganisms from crude-oil contaminated sites and evaluating their degradation capacities are vitally important in the remediation of oil-polluted environments and crude-oil exploitation. In this research, new hydrocarbon-degrading bacteria and fungi were isolated from the crude-oil contaminated soil of the oil-fields in the Amazon rainforest of north-east ...

  • Effects of two fungicide formulations on microbial and macroinvertebrate leaf decomposition under laboratory conditions

    Aquatic fungi contribute significantly to the decomposition of leaves in streams, a key ecosystem service. Little is known, however, about the effects of fungicides on aquatic fungi and macroinvertebrates involved with leaf decomposition. Red maple (Acer rubrum) leaves were conditioned in a stream to acquire microbes (bacteria and fungi) or leached in tap water (unconditioned) to simulate ...

  • Post Harvested Stored Wheat Grain: Fungal Infestation and Nutrition

    The wheat grain production in any country varies from year to year and hence the grains should be stored strategically from years of overproduction for the use in year of under production. Also grain must be stored for several other reasons such as point of ...


  • Effect of gaseous chlorine dioxide on indoor microbial contaminants

    Traditional and modern techniques for bioaerosol enumeration were used to evaluate the relative efficiency of gaseous chlorine dioxide (ClO2) in reducing the indoor microbial contamination under field and laboratory conditions. The field study was performed in a highly microbially contaminated house, which had had an undetected roof leak for an extended period of time and exhibited large areas of ...

  • Aflatoxin & ochratoxin sample preparation columns

    Simultaneous Analysis of Aflatoxins and Ochratoxin A - Sample Preparation Aflatoxins and Ochratoxin A are produced by fungi, e.g. Aspergillus and Penicillium species. Therefore both toxin types are found together in many foods and animal feeds, e.g. cereals. Thus it is appropriate to analyze one extract for the occurrence of both mycotoxins in a single step. A significant assistance ...

  • Converting plant waste into biofuels

    Promising advances using yeast and fungi. Written by Nancy W. Stauffer. You can read the original story in MIT News MIT researchers are genetically engineering yeast to break down stubborn plant fibers into sugars that it can then ferment — a first ...

  • Building Services Management - Air Sampling -

    Untitled Document Maintenance professionals are often the first responders to mold complaints in their facilities. building occupants can be exposed to fungal (mold) ...

  • Allergies & asthma may be worsened by synthetic bedding

    EMSL Analytical has been on the forefront of providing quick and affordable allergen testing solutions for industry and the public. A recent study conducted at Otago University in New Zealand found that synthetic bedding typically contains greater numbers of fungal cell components than feather bedding. The research found that high levels of beta glucans, from fungi, were regularly found in ...


  • Sick-building syndrome and building-related illness

    Significant health problems linked to very poor indoor air qualityIndoor Air Quality (IAQ) deals with the content of interior air that could affect health and comfort of building occupants. The IAQ may be compromised by microbial contaminants (mold, bacteria), chemicals (such as carbon monoxide, radon), allergens, or any mass or energy stressor are more prevalent than anyone could have predicted. ...

  • Multi-residue mycotoxin analysis single run analysis of deoxynivalenol, aflatoxins, ochratoxin a, zearalenone and fumonisin by HPLC and post-column derivatization

    Although Aspergillus (Aflatoxins, Ochratoxin A) are generally associated with peanuts and Fusarium (Deoxynivalenol , Zearalenone) with wheat, these fungi and those that produce other toxins are not host selective and so can cross plant species. This situation is complicated by the fact that the microscopic mold may not be visible to the naked eye. Also, when infected grains are processed, any ...

  • Safety in handling wood pellets

    Canada is primarily a bulk producer and exporter of pellets with large mills that make, on average, 56,000 tonnes per year, said Staffan Melin. When shipped in large volumes, pellets are classified as hazardous material, although wood pellets in consumer bags are benign. For example, carbon monoxide (CO) gas emissions released by pellets killed a person in the cargo hold of a ship in 2002. A ...

  • Sequential extractions on mine tailings samples after and before bioassays: implications on the speciation of metals during microbial re-colonization

    Abstract  Mine tailings may be remediated using metal tolerant microorganisms as they may solve the limiting conditions for healthy development of plants (i.e., low organic mater content and poor physical conditions). The aim of this study was to investigate the consequences of microbial colonization on the chemical speciation of trace metals. Surface samples from the Valenciana mine ...


  • Enzyme Activities and Chemical Changes in Wet Olive Cake after Treatment with Pleurotus ostreatus or Eisenia fetida

    Abstract  A laboratory experiment was conducted to evaluate the enzyme activities and chemical changes recorded in a recalcitrant phenolic-rich waste after treatment with Pleurotus ostreatus or Eisenia fetida. The waste used was wet olive cake (alperujo in Spanish), a waste produced in huge amounts by the olive oil industry. Both P. ostreatus and E. fetida were very effective in removing ...


  • Microbial community structure and functioning along metal pollution gradients

    Toxic effects of heavy metals on soil microorganisms have been confirmed in a number of laboratory studies. However, most real‐field studies do not allow for strong general conclusions due to a range of problems, such as pseudoreplication and confounding factors, which are almost impossible to control for with the most commonly used polluted‐vs.‐unpolluted or random sampling designs. Effects ...

  • Removing biofilm from membranes – a practical approach

    Abstract Within the lifetime of most reverse osmosis (RO) systems some fouling will adversely affect membrane performance.One of the major foulants identified on lead membranes during a decade of membrane autopsy at the Genesys Membrane laboratory is biological fouling (biofouling). All raw water sources contain microorganisms such as algae, bacteria and fungi. They also contain ...

  • Fungal Biodegradation

    Introduction The utilization of fungal biodegradation involves the controlled usage of these specially cultivated fungi to treat contaminants. White Rot Fungus White rot fungus has been reported to degrade a wide variety of organopollutants because of its lignin-degrading or wood-rotting enzymes. Two different treatment configurations have been tested for white rot fungus, in situ and ...

  • Biofilm Control for Industrial Waters

    Industrial operations can face a number of serious problems due to bacterial Biofilms growing in process water systems and cooling tower waters. Biofilm-induced corrosion, mechanical blockages and impedance of heat transfer processes result in huge monetary losses each year. In engineered systems, additional risks of biofilm-mediated contamination include negative public health consequences and ...
