Beer Contamination Detection by Sterile Filtration

This comprehensive microbiological analysis utilizes sterile filtration and a variety of selective media in order to detect and quantify potential yeast and bacterial beer spoilers. A 100mL sample is filtered and grown on UBA, WLD, MRS (with cycloheximide), Lysine, and LWYM under aerobic and anaerobic conditions. Any growth is then catalase tested and gram stained. Results include total Colony Forming Units (CFUs) per 100mL sample, CFUs per growth formation and microscopic pictures of the growth. If samples have a high biological load or are unable to move through the filters, spread plate methods will be utilized. Sample requirements: three 12oz. duplicate containers per sample being analyzed.
