Insights into extracellular polymeric substances of cyanobacterium Microcystis aeruginosa using fractionation procedure and parallel factor analysis

Variations in abundance and community composition of denitrifying bacteria during a cyanobacterial bloom in a eutrophic shallow lake in China

“…It is well known that the majority of denitrifying bacteria prefer an anaerobic environment. Cyanobacteria usually aggregate through the coagulation of extracellular polymeric substances and then form mucilaginous aggregates of different sizes (Xu et al 2013). The mucilaginous sheath prevents gas exchange and provides a favorable anaerobic microenvironment (Ploug et al 1997).…”

Effects of iron on growth, antioxidant enzyme activity, bound extracellular polymeric substances and microcystin production of Microcystis aeruginosa FACHB-905

“…The extraction of EPS was performed according to the method reported by Xu et al (2013). Twenty milliliters of M. aeruginosa solution was firstly centrifuged at 2500 g for 10 min, and the harvested algal cells were re-suspended in a 0.05% NaCl solution.…”

Combination of two-dimensional correlation spectroscopy and parallel factor analysis to characterize the binding of heavy metals with DOM in lake sediments

“…EEM spectra were gathered with scanning emission (Em) spectra from 250 to 550 nm at 2 nm increments by varying the excitation (Ex) wavelength from 200 to 450 nm at 10 nm increments. The spectra were recorded at a scan rate of 1200 nm min −1 , using Ex and Em slit bandwidths of 5 nm [26].…”
