Mutants having a producing ability of 1,4-butanediol and method for preparing 1,4-butanediol using the same

open access: yes, 2015
A mutant capable of producing 1,4-butanediol and a method of preparing 1,4-butanediol using the same are provided. The mutant microorganism is prepared by introducing and amplifying genes encoding enzymes converting succinate into 4-hydroxybutyrate and 4-

PRODUCTION AND PROPERTIES OF 2,3-BUTANEDIOL: XI. EVALUATION OF LEVO-2,3-BUTANEDIOL AS A NON-VOLATILE ANTIFREEZE COMPOUND

open access: yes, 1946
levo-2,3-Butanediol is more effective than glycerol and less effective than ethylene glycol as a freezing point depressant for water. The considerable discrepancy that is reported between observed freezing points and values calculated from Raoult's law ...

A chemo‐enzymatic colorimetric cascade for detecting ethylene glycol contamination

open access: yesThe FEBS Journal, EarlyView.
A chemo‐enzymatic cascade is developed for ethylene glycol (EG) detection. EG is oxidized by GoADH with C1‐mediated cofactor recycling to produce glycolaldehyde (GAL). GAL subsequently reacts with purpald to generate a detectable purple chromophore.

Insights into tandem dioxygenases—copper radical oxidases in fungal Phytopathogens of the Colletotrichum acutatum species complex

open access: yesThe FEBS Journal, EarlyView.
In Colletotrichum acutatum species complex, conserved ring‐cleavage dioxygenases located adjacent to AA5_2 enzymes were investigated as potential redox partners. Biochemical analyses identified the dioxygenases as intradiol‐cleaving enzymes preferentially oxidizing methyl‐substituted catechols, while AA5_2 enzymes displayed weak alcohol oxidase ...

PRODUCTION AND PROPERTIES OF 2,3-BUTANEDIOL: VI. DEHYDRATION BY SULPHURIC ACID

open access: yes, 1945
Dehydration of 2,3-butanediol in the liquid phase with 3 to 20% of sulphuric acid gave water, butanone-2, and the cyclic methyl ethyl ketal of 2,3-butanediol as the chief products, the total yield of liquid products being about 96%.

Effect of denture cleansers and surface treatments on the color stability, gloss, and wettability of CAD‐CAM denture bases

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the impact of surface treatments and chemical denture cleansers on the surface color stability, gloss, and wettability of compression‐molded, 3D‐printed, and milled denture base materials. Materials and Methods Specimens (12 × 16 × 7 mm) were fabricated from a standardized STL file in three denture base materials ...

High Resolution Millimeter Wave Absorption Spectroscopy of Flexi- ble Complex Organic Molecules: Laboratory Spectrum of 1, 2-butanediol

open access: yes, 2017
The enhancing sensibility of radioastronomical observations allows for detec- tion of complex organic molecules (COMs) with increasing size. Observations performed by the Atacama Large Millimeter Array (ALMA) open up new oppor- tunities to reveal the ...

Deciphering Role of Endophytes in Plant Defences and Biotic Stress Resilience Across Families

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Plant families generate distinct repertoires of specialised metabolites that govern their biotic interactions. Endophytes strengthen host plant defence mechanisms and tolerance to biotic challenges by upregulating metabolite biosynthesis, modifying precursor compounds into more potent forms, or by directly synthesising analogous defence ...

A Quantitative Analysis of Street‐Level Drugs Seized in New South Wales, Australia: Purity, Dose and Adulterants

open access: yesDrug and Alcohol Review, Volume 45, Issue 7, November 2026.
ABSTRACT Introduction The Combined Surveillance and Monitoring of Seized Samples (CoSMoSS) program is a joint harm reduction initiative between NSW Health and NSW Police Force. Here, we examine the contents and purity of a sample of seized suspected target drugs (cocaine, heroin, methamphetamine and 3,4‐methylenedioxymethamphetamine ‘MDMA’).
