Training content:
– Preparation of culture media, sterilization techniques (media and equipment).
– Aseptic sampling (from equipment vs in a finished product).
– Microscopic analysis of pure collection strains, beer, water: fresh mount, Gram staining.
– Microbiological analysis of beer by filtration vs by plating on selective media vs by forcing tests : microscopic and macroscopic observations of results, comparative analysis, decision tree for beer spoilers.
– Quantification of an inoculum / population of a brew (total count vs viable, direct count vs indirect, manual count vs automatic): counting, expression, analysis and comparison of different results. Advantages and disadvantages of different approaches.
– Strain revival : scaling up (from cryotube to culture).
– Industrial hygiene: surface hygiene control (rodac, dipslide, swabbing, petrifilms, …), air microbiological quality control, …
