  • Air Quality Testing

    Airborne mold, bacteria and other microorganism are known to cause asthma, hypersensitivity, allergic reactions, toxic effects and other disease manifestations in humans. The monitoring of the indoor air and environment for the presence and level of microbial contamination is therefore of paramount significance particularly for evaluating potential adverse health effects.

    Comprehensive microbiological monitoring of indoor environment begins with a walkthrough survey for assessing the nature and extent of the problem and developing a monitoring strategy. This is followed by collection of indoor air samples; surface sampling; and bulk sampling of household dust, wood, carpets, and any materials suspected to have mold contamination. In addition, water samples from drip pans, humidifiers and air conditioners may also be collected as part of the surveillance strategy.

    The main objectives of monitoring indoor environment and air quality include, determination of the presence and level of mold and bacterial contamination, estimation  of predominant molds, identification at genus and species level, and determination of contamination source for undertaking remedial actions.

    PBR provides interpretation of test results based on the guidelines and exposure standards (limits) of relevant national and international organizations. These include: Health Canada, American Conference of Government Industrial Hygienists (ACGIH), United States Environmental Protection Agency (EPA), European Union (EU) and World Health Organization (WHO). A list of specific tests is given in the table below.

    Specific Tests for Indoor Air Quality Monitoring
    Heterotrophic Plate Count, (Bacteria) Aspergillus/Penicillium Group
    Staphylococcus aureus Stachybotrys chartarum
    Pseudomonas aeruginosa Bacteria and Mold Identification
    Legionella species Microbial Biomass Determination
    Legionella pneumophila Pet Antigen Detection
    Bacterial Endotoxin Dust Mites Detection
    Fungal (Mold/Yeast) Count Other pathogens of concern on request
  • Equipment Rental and Sampling Supplies

    PBR provides rental equipment, sampling materials, supplies, and offers advice for proper tests and procedures if clients are qualified to do the sampling. However, it is recommended that clients involve PBR’s qualified staff in designing the sampling scheme and protocol to ensure the relevance of the laboratory results to the problem under investigation.

  • Soil Testing

    PBR offers complete analytical services for microbiological quality assessment and characterization of agricultural and contaminated soils based on the tests listed in the following table. These tests and parameters are useful in determining the level and source of microbiological contamination as applicable to environmental impact assessment, soil bioremediation, and soil fertility evaluation.

    NOTE: For chemical analysis of soil, please look for  Soil Quality Test under Chemical/Environmental services.  

    Specific Tests for Soil Microbiology
    Microbial Biomass Determination Bacillus cereus
    Heterotrophic Plate Count (Bacteria) Salmonella spp.
    Nitrogen Cycle Bacteria Total Coliform/Fecal Coliform
    Fecal Streptococcus Group Fungal (Yeast/Mold) Count

  • Environmental Microbiology

    PBR offers specialized testing for the presence and level of microorganisms that are of significance in diverse environmental and industrial processes and systems, including cooling towers. These involve microorganisms that are responsible for biological corrosion, biofouling, biofilm (slime) formation and other health hazards.

    Corrosion, Biofouling and Biofilm microorganisms

    Corrosion and clogging of iron and steel pipes can occur due to the growth of microorganisms such as iron related bacteria (IRB’s) and sulfate reducing bacteria (SRB’s).

    Biofouling is the undesirable accumulation of microorganisms, plants or algae on surfaces and structures that are in contact with water for a period of time. The three most important agents involved in biofouling are IRB’s, SRB’s, and Heterotrophic Aerobic Bacteria (HAB’s).

    Biofilm is an aggregate of diverse microorganisms in which cells adhere to each other on a surface. These adherent cells are generally embedded within a self-produced matrix of extracellular polymeric substances, which are also referred to as slime. Biofilms may form on living or non-living surfaces and can be prevalent in natural, hospital, industrial and wastewater settings.

    Presence of Legionella species in cooling towers, air conditioners, humidifiers and drip pans is a major health concern.

    Bioremidiation Applications

    PBR can provide microbial consortia capable of degrading harmful contaminants in the treatment of industrial effluents and contaminated soils. PBR also provides testing for hydrocarbon utilizing bacteria and nitrogen cycle bacteria. Specific tests and parameters for all of the above matrices and processes are listed in the following Table.

    Specific Tests for Biofouling, Biofilm, Corrosion and Other Environmental Samples
    Heterotrophic Aerobic Bacteria (HAB) Iron Related Bacteria (IRB’s)
    Slime Forming Bacteria and Fungi Microbial Biomass Determination
    Pseudomonas aeruginosa biofilms Legionella spp.
    Nitrifying/Denitrifying Bacteria Acidifying Bacteria
    Hydrocarbon Utilizing Bacteria Wastewater Microbial Consortia
    Sulfate Reducing Bacteria (SRB’s) Algae Enumeration and Identification
  • Product Efficacy and Sterility Evaluation

    PBR provides specific testing services to determine and evaluate the anti-microbial activity and efficacy of various products, as well as to ascertain the level of bacterial and fungal contamination (product sterility). Most commonly tested products include, pharmaceuticals,  probiotics, consumer and industrial products. 

    Efficiacy and Sterility microbiological tests are performed using Standards and Protocols of the United States Pharmacopoeia (USP), Canadian General Standards Board (CGSB), Association of Official Analytical Chemists (AOAC), International, American Society of Testing Materials (ASTM) and International Organization for Standardization (ISO).

    Efficacy of Specific Products

    Antimicrobial Agents: We provide MIC (Minimum Inhibitory Concentration) testing of pharmaceutical products, using standard protocols.

    Sanitizers and Disinfectants: We offer efficacy testing using standard microbial cultures and recommened based test methods on applicable guidelines.

  • Bacterial and Fungal Identification

    The genus and species level identification of microorganisms present in food, air, water, soil and other matrices is essential for the safety evaluation and assessment of potential health hazards, as well as for the required regulatory compliance and approval.

    PBR provides comprehensive microbiological services for the identification of non-pathogenic and pathogenic bacteria, mold and yeast in food, water, air, soil and other environmental samples. Generally, both bacteria and fungi are identified to the genus level, but species, strain and serotype levels identification is provided if and as required.

    Basic microbiological techniques, microscopic examination, biochemical methods and specific automated systems are used for the genus and species level identification of bacteria, yeast and mold present and detected in diverse samples. PBR employs  state-of-the art PCR technology,  VITEK 2 automated system (from BioMerieux)  and Biolog Gen III that provide highly accurate and reproducible results for the identification of microorganism that are of clinical, hygienic and environmental significance.
