Organic particle scavenging by marine bacteria: influences of bacterial nanoscale surface properties.

ABSTRACT: Marine bacteria contribute to biogeochemical cycles by scavenging organic nanoparticles such as cell fragments, viruses, excretions from phytoplankton and bacteria, and naturally occurring polymeric substances. Nonetheless, bacterial surface properties influencing this process remain poorly understood. A previous study found that marine bacteria exhibit significant variation in surface roughness, which affects nanoparticle attachment, influencing bacterial survival and marine biogeochemical cycles. However, cell surface characteristics such as Young's modulus and adhesiveness have rarely been measured. This study investigated bacterial nanoscale surface properties and their effects on nanoparticle attachment. Atomic force microscopy was employed to measure these parameters of 559 individua
