Pika FastOrange B is a nutrient medium developed specifically for the craft brewing market, it is used for the detection of beer spoiling microorganisms throughout the entire production process. The FastOrange B will change colors based on the presence of bacteria, such as lactobacilli and pediococci, allowing for easy visual assessment of contamination.
This enrichment media serves many purposes, first and foremost, as an identifier of spoilage organisms, and isolation of infection point. If there is a contamination in your beer, use the FastOrange B to determine where that bacteria is being picked up. Once an infection is isolated, the bacteria can be sent to a lab for PCR analysis, where you can find out exactly what bacteria is causing your beer problems. In this same way, positive bacterias can be isolated as well, and propagated for further brewing/souring!
FastOrange B Agar is a culture medium developed specifically for the detection of microbial contaminations during the brewing process and in brewery products. Beer spoilers such as lactic acid bacteria and pediococci are easily detected by a color change in the culture. The strength of this color change is relative to the acid production of the bacteria, and can be a useful tool for isolating high acid producing strains for further propagation.
