Bacterial Synthesis of p-Aminobenzoic Acid.

open access: yesExperimental Biology and Medicine, 1943
SummaryRepresentative cultures of many bacterial genera were grown in culture media of known composition free of p-aminobenzoic acid. Culture filtrates and hydrolized whole cultures were assayed for p-aminobenzoic acid content employing the Acetobacter suboxydans microbiological method.

Psilocybin Production With Genetically Modified Aspergillus nidulans Under Pressurized Conditions

open access: yesBiotechnology and Bioengineering, EarlyView.
Shake flask cultures of psilocybin‐producing A. nidulans were investigated with respect to nitrogen source, rheology, power input, and oxygen availability, and subsequently scaled to a stirred tank reactor scale based on specific power input to develop and optimize a pressurized bioprocess.

SEPARATION OF p-AMINOBENZOIC ACID BY REACTIVE EXTRACTION. 1. MECHANISM AND INFLUENCING FACTORS [PDF]

open access: yesChemical Industry and Chemical Engineering Quarterly, 2008
The comparative study on the reactive extraction of p-aminobenzoic acid with Amberlite LA-2 and D2EHPA in two solvents with different polarity (n-heptane and dichloromethane) indicated that the extractant type and solvent polarity control the extraction ...

Contact Allergy to Ingredients of Hair Cosmetics Associated with Occupational and Non‐Occupational Exposure—Trends from 1995 to 2020 in Central Europe, with or without Regulation

open access: yesContact Dermatitis, EarlyView.
Among 2678 female hairdressers and 6244 female consumers with contact dermatitis suspected to be related to use of hair cosmetics, including dyes, patch tested in the IVDK between 1995 and 2020, diverging contact allergy trends were observed. In the case of toluene‐2,5‐diamine (PTD) shown in the figure, sensitization was at a stable, high level in ...

Selective targeting of cortactin tandem repeat acetylation by human lysine deacetylases

open access: yesThe FEBS Journal, EarlyView.
Cortactin function is regulated by acetylation at several lysine residues within its tandem repeat region. Using genetic code expansion to generate cortactin variants containing precisely defined acetylation marks, we show that HDAC6 is the primary enzyme removing these modifications, with SIRT1 and SIRT2 also acting at selected sites but with lower ...
