Microbiological laboratory at DTH undertakes quality Inspection and certification for industries associated with raw and processed food, water, Dairy Product, U.V based water purifier Phenolic type disinfectant etc. The lab is well equipped, with state of art facilities and experienced scientists
Capabilities of DTH
Product Quality Certification, Projects, Consultancy & Training
Product Quality Inspection and Certification
Detection of Pathogens, Enumeration of Spoilage Micro-Flora, Disinfections Efficacy, Sterility Testing and Bio-Burden & Microbiological Monitoring of Indoor Air.
Library of Micro-Organism at DTH
Escherichia coli, Vibrio cholera, Vibrio parahaemolyticus, Faecal streptococci, Staphylococcus aureus, Pseudomonas aeruginosa,  Aspergillus, Bacillus cereus, Salmonella, Shigella, Listeria, Bacillus sub tiles, Micrococcus luteus, Clostridium perfringens & Saccharomyces cerevaceae
Standards Followed
A.P.H.A. , B.I.S.,   A.D.A.C & Conventional Methods
What is Spoilage microorganisms
Microorganisms are ubiquitous in nature. Quality and shelf life of any product depends on presence and nature of Microorganisms contained in it. Under favorable conditions these Microorganisms proliferate and result in loss of product quality. Microbiology monitoring is an essential part of quality control. DTH plays an important role in testing and certification.
Test inadequacy
Standard Plate Count, Coliforms/ Faecal coliforms, Psychrophilic and Thermophilic, Aerobic and an-aerobic spore formers, Anaerobic bacteria,  Sulphite Reducing Bacteria, Sulphur and Iron Bacteria, Yeast and Moulds, Microbiological test in U.V based water purifier, Rideal walker coefficient in Phenolic type disinfections
Residual Anti-Microbial Substances
Food-producing animals are given antimicrobial drugs for prevention of disease and for their well-being. The residues of these antimicrobial drugs remain in and on the body of the animals. Following anti-microbial residues are being tested at ppb levels using ELISA techniques. Tetracycline, Sulfonamidesm, Streptomycin, Chloramphenicol, Gentamycin, Neomycin, Nitrofurans etc
Mycotoxins
Mycotoxins are carcinogenic, highly toxic metabolites of fungi like Aspergillus, Fusarium and Penicillium. They are toxic even in trace quantities
Sterility Testing
Sterility is a mandatory requirement for all injectables, ophthalmic preparations and surgical devices. Sterility test is conducted in accordance with various pharmacopoeia viz. IP, USP, BP etc. Following products are being tested.
Bioburden Estimation
Terminally sterilized products are assessed for their microbial loads prior to sterilization. This helps in standardization of sterilization loads. DTH also undertakes method validation studies for bio-burden estimation in surgical devices
Monitoring of Indoor Air
DTH carries out air-monitoring studies for presence of microbes. Services are provided in the following areas. Storage Godowns, Hotels/Restaurants, Food Processing/Packaging Areas, Clean Rooms/Clean Air Devices, Operation Theatres and Intensive care units in hospitals
Anti Bacterial Efficacy of Nanotechnology based devices/filters
ilters are checked for anti bacterial efficacy against a number of challenge organisms like E. coli, Salmonella, Shigella, Vibrio, Staphylococcus, Pseudomonas and Micrococcus luteus.
Disinfections Efficacy
The Phenolic and non-Phenolic type disinfectants are being tested for their germicidal value as per National and International protocols.
