A theoretical investigation of the organic carbon-microbial biomass relation in muddy sediments

摘要: A population/diagenetic model is developed to describe the behavior/dynamics of the microbial biomass in aquatic sediments. This model is analyzed in order to establish the dominant terms, ie processes, in that balance. The result of this analysis shows that production-removal processes, ie growth, death, grazing, transformation to inactive or active, etc., are essentially in balance to the best (lowest order) approximation, while all varieties of transport processes, ie motility, chemotaxis, bioturbation, burial, etc., contribute only higher …
