CABI’s unique UKAS accreditation now covers molecular identification of bacteria, filamentous fungi and yeasts

CABI’s UKAS accreditation to ISO 17025 now includes molecular identification to species level of filamentous fungi and yeasts by ITS rRNA gene sequencing, in addition to molecular identification of bacteria by 16S rDNA gene sequencing.

This service is unique in the UK, as it is the only service to be accredited by UKAS for the entire identification process including providing the name of the organism.

CABI already holds UKAS accreditation for a wide range of microbial testing. UKAS accreditation provides an assurance of competence, impartiality and integrity.

New screening tool from CABI and Enzagen

CABI’s Microbial Services team is undertaking a new initiative with Enzagen, to provide simple ready to use microbial 'panels' as screening kits. Streptomet, the first kit, is aimed at metabolite screening such as hydroxylation and glucuronidation reactions. The kit comprises freeze-dried biomass from 20 different Streptomyces cultures. Further details, including ordering and prices are available through Enzagen, at


CABI's Microbial Identification Service provides an international, high quality, confidential service for the identification of filamentous fungi, yeasts and bacteria. We serve clients from a range of industries including the pharmaceutical, food and manufacturing sectors, as well as research organisations working in agriculture, horticulture, quarantine, biodiversity assessment and biological control.


We manage a collection of over 28,000 living strains including the UK National Collection of Fungus Cultures. The culture collection contains over 6,000 species isolated from environmental and agricultural systems worldwide, making it one of the most significant in the world.  

Our range of organisms consists of filamentous fungi and yeasts, plant pathogenic bacteria, including extremophiles, metabolite producing strains, biological control agents and many more.

We provide a broad range of microbial investigation, testing and consultancy services, both off-site and at our UKAS accredited facilities.

Our experts can:

  • investigate fungal contamination problems in both the home and workplace, and advises how to minimise risk conduct on-site mould contamination testing, and air testing for fungal spores

  • carry out mould growth testing to internationally recognised standards

  • test and monitor fuel for microbial contamination, as overseen by our dedicated team at Conidia Bioscience.

Member countries in bands 1-4 (ie with a UN Index Number between 0 - 0.999) are entitled to free identifications of microbial samples. The free service provides specifically for identification of bacteria and fungi of agricultural/ horticultural importance or origin, relating to food security or plant health, including quarantine organisms.

More information on country eligibility and how to access services and submit samples is available to Member Countries.

Within each qualifying Member Country, the free service is available to: National and Regional Agricultural Research Centres Government Institutions responsible for agriculture and food security University Departments whose studies relate to agricultural research.

A limited number of identifications can be provided under the scheme:
• A maximum of five samples per institution may be submitted at any one time
