생물막 성장에 대한 세균의 초기 분포영향을 나타내는 셀룰라오토마톤 모델 = Cellular Automaton Models Revealing Effects of Initial Bacterial Distribution on Biofilm Growth

다국어 초록 (Multilingual Abstract)

Two dimensional cellular automaton (CA) models were developed to investigate growth of biofilms in aquatic ecosystems. Simple local rules on CA were applied to governing growth of bacterial populations in relation to different nutrient concentrations. Initial bacterial distribution played an important role in determining population size and morphology of biofilm at low concentrations of nutrition. With clumped distribution, population size increased slowly compared with uniform and random distributions, while the porosity tented to be higher with uniform distribution compared with other initial distributions.
