Keywords: microbial growth, white water
The closing of the whitewater cycle increases the amount of nutrients available for the micro-organisms living in papermachine. The microbial flora in papermachines can vary a lot. The type and concentration of nutrients and the operating conditions of the papermachine (for example pH and temperature) affect on the type of microbes that may live there. Strong microbial contamination has negative impact to the quality of the products and the operation of the papermachine. In this project microbes isolated from papermachines are cultivated in different concentrations of whitewater and with different pH and temperature values. The cultivations of microbes and modeling of the microbial growth are used to find out how the closing of the whitewater cycle affects on the microbial growth in papermachines
