ZZE-Configuration of chromophore ß-153 in C-phycocyanin from Mastigocladus laminosus [PDF]

, 1987
The photochemistry of C-phycocyanin has been studied after denaturation in the dark. It shows an irreversible reaction which has characteristics of a Ζ,Ζ,Ε- to Z,Z,Z-isomerization of dihydrobilins. Its amplitude depends on the reaction conditions, with

Oxyfluorfen-resistant rice tolerance and weed control when using oxyfluorfen

Weed Technology
Abstract Herbicide-resistant barnyardgrass and weedy rice control, without crop injury, is a challenge for rice producers in the United States. Herbicides not initially labeled for rice, such as oxyfluorfen, are now being evaluated as new tools for weed control.

Strategies for the electrobioremediation of oxyfluorfen polluted soils [PDF]

Electrochimica Acta, 2019
This work compares three strategies for the in-situ remediation of oxyfluorfen polluted clay soil, based on the combination of biological processes and electrokinetics (EK): (i) EK-biostimulation, in which the action of microorganisms contained in soil is promoted without the use of biological permeable barriers, (ii) EK-bioaugmentation with fixed ...
