Development of pretreatment protocol for DNA extraction from biofilm attached to biologic activated carbon

Shuting ZHANG, Bo WEI, Xin YU, Bing LIU, Zhuoying WU, Li GU

Frontiers of Environmental Science & Engineering 2010, Volume 4, Issue 4,   Pages 459-465 doi: 10.1007/s11783-010-0249-3

Abstract: The biologic activated carbon (BAC) process is widely used in drinking water treatments. A comprehensive molecular analysis of the microbial community structure provides very helpful data to improve the reactor performance. However, the bottleneck of deoxyribonucleic acid (DNA) extraction from BAC attached biofilm has to be solved since the conventional procedure was unsuccessful due to firm biomass attachment and adsorption capacity of the BAC granules. In this study, five pretreatments were compared, and adding skim milk followed by ultrasonic vibration was proven to be the optimal choice. This protocol was further tested using the vertical BAC samples from the full-scale biofilter of Pinghu Water Plant. The results showed the DNA yielded a range of 40 μg·g BAC (dry weight) to over 100 μg·g BAC (dry weight), which were consistent with the biomass distribution. All results suggested that the final protocol could produce qualified genomic DNA as a template from the BAC filter for downstream molecular biology researches.

Ozonation as an efficient pretreatment method to alleviate reverse osmosis membrane fouling caused by

Xuehao Zhao, Yinhu Wu, Xue Zhang, Xin Tong, Tong Yu, Yunhong Wang, Nozomu Ikuno, Kazuki Ishii, Hongying Hu

Frontiers of Environmental Science & Engineering 2019, Volume 13, Issue 4, doi: 10.1007/s11783-019-1139-y

Abstract:

Humic acids (HA) didn’t cause obvious reverse osmosis (RO) membrane fouling in 45 h.

Osmotic pressure (NaCl) affected slightly the RO membrane fouling behavior of HA.

Ca2+ promoted aggregation of HA molecules and thus aggravated RO membrane fouling.

Ozonation eliminated the effect of Ca2+ on the RO membrane fouling behavior of HA.

The change of the structure of HA was related to its membrane fouling behavior.
