From: The dishwasher rubber seal acts as a reservoir of bacteria in the home environment
Comparisons of the bacterial species diversity on the rubber seals of the three sampled dishwashers that showed the highest cultivation-dependent bacterial diversity, which were supplied with hard tap water. Dishwasher 6 (a) and dishwasher 10 (b) were both supplied with moderately hard tap water (1.6 mmol/L CaCO3), and dishwasher 29 (c) was supplied with hard tap water (2.0 mmol/L CaCO3). Different colors convey bacterial classes e.g. Bacilli are represented in red, Proteobacteria are represented in green, Actinomycetes are represented in blue and Bacteroidetes are represented in purple colour
