15.3 Microbial Growth on Surfaces and Biofilms 表面生长与生物膜 Surfaces are important microbial habitats because:固体表面是重要的微生物生活环境: ·Nutrients can adsorb to them;营养可吸附于表面 In the microenvironment of a surface,nutrient level may be much higher than they are in the bulk solution. 微环境的固体表面有更高的营养物水平(与水环境相 比)。 A surface may itself also be a nutrient,such as a particle of organic matter.固体表面可能本身就是营养 8 Microbiology,Shanghai Jiao Tong University
