High-rate partial-nitritation and efficient nitrifying bacteria enrichment/out-selection via pH-DO controls: Efficiency, kinetics, and microbial community dynamics
TL;DR: To enhance PN process via nitrifying bacteria enrichment/out-selection within psychrophilic environment, a novel pH-DO (dissolved oxygen) control strategy was proposed and the response of PN, kinetics, AOB enrichment, and NOB out-selection efficiency was investigated during start-up and long-term operation.

Screening of Brazilian plant extracts for antioxidant activity by the use of DPPH free radical method
Luciana Lopes Mensor,Fábio de Sousa Menezes,Gilda Guimarães Leitão,Alexandre da Silva Reis,Tereza Cristina dos Santos,Cintia S. Coube,Suzana G. Leitão +6 more
TL;DR: As a general rule the ethanol extracts of plants belonging to the Verbenaceae family showed lower EC50 values than the other plant extracts, among the partitions, the more polar ones (ethyl acetate and n‐butanol) are those that generally have higher antioxidant activity (AA).
