Decomposition mechanism of pentlandite during electrochemical bio-oxidation process

Transactions of Nonferrous Metals Society of China, 2012
Abstract Electrochemical measurements were carried out to elucidate decomposition mechanism of pentlandite using modified powder microelectrode with Acidithiobacillus ferrooxidans attached or without on the mineral powder surface. Cyclic voltammetry (CV) results show that at a low potential of about −0.2 V (vs SCE), the pentlandite was transformed to

The Impact of Curcumin, Gingerol, Piperine, and Proanthocyanidin on the Oxidative Stability of Sunflower and Soybean Oils for Developing Bio-Lubricants

Lubricants
Vegetable oils can serve as a fundamental raw material for formulating lubricants due to their exceptional lubricating properties, which are indicated by viscosity indexes greater than 100. Vegetable oils, due to their unsaturated fatty acids with one or

Bio-oxidation of pyrite, chalcopyrite and pyrrhotite by Acidithiobacillus ferrooxidans

Chinese Science Bulletin, 2007
This paper deals with the bio-oxidation processes by Acidithiobacillus ferrooxidans of pyrite, chalcopyrite and pyrrhotite. Our experimental results show distinctive bio-oxidation characteristics for the three sulfide minerals. In the presence of A. ferrooxidans, the sulfide oxidation rates generally decrease in the order of pyrrhotite, chalcopyrite ...

Bio-upcycling of even and uneven medium-chain-length diols and dicarboxylates to polyhydroxyalkanoates using engineered Pseudomonas putida

Microbial Cell Factories
Bio-upcycling of plastics is an emerging alternative process that focuses on extracting value from a wide range of plastic waste streams. Such streams are typically too contaminated to be effectively processed using traditional recycling technologies ...
