Characterizing the growth of PHA-producing microorganisms on short-chain carboxylic acids [PDF]

open access: yesMicrobial Cell Factories
Short-chain carboxylic acids are important chemical intermediates in anaerobic treatment or thermal hydrolysis of biowaste. They are a crucial precursor for the production of Polyhydroxyalkanoate (PHA) by various microorganisms. However, there is limited

Application of cationic dye pyronin G (Y) for quantitative extraction-photometric determination of higher carboxylic acids in fi sh [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Серия Химия. Биология. Экология, 2022
The relevance of this study is due to the need to develop methods for the extraction and quantitative determination of higher carboxylic acids in fi sh. In this work, we propose a simple, inexpensive, and highly sensitive extraction-photometric technique

Carboxylic acids and light interact to affect nanoceria stability and dissolution in acidic aqueous environments

open access: yesBeilstein Journal of Nanotechnology, 2023
Cerium atoms on the surfaces of nanoceria (i.e., cerium oxide in the form of nanoparticles) can store or release oxygen, cycling between Ce3+ and Ce4+; therefore, they can cause or relieve oxidative stress within living systems.

Corrosion protection of AA2024 sealed anodic layers using the hydrophobic properties of carboxylic acids [PDF]

open access: yes, 2009
The present study investigates the use of carboxylic acids as a post-treatment for sealed AA2024 anodised in tartaric–sulphuric acid electrolyte. Four monocarboxylic acids with different carbon chain lengths were tested ((CH3–(CH2)n–COOH with n=4, 8, 12 ...
