Identification of mycobacteria species by molecular methods. [PDF]

open access: yesInt Wound J, 2020
Abstract In this study, mycobacteria, which were previously identified as Mycobacterium tuberculosis complex (MTC), and mycobacteria other than tuberculosis (MOTT) with cord factor and the p‐nitro‐alpha‐acetyl‐amino‐beta‐hydroxypropiophenone (NAP) test were reanalysed using the polymerase chain reaction—restriction fragment length polymorphism (PCR ...

Copper-Catalyzed Carbonylative Cyclization of CO<sub>2</sub>: A Promising Approach for Synthesis of Flavone. [PDF]

open access: yesAdv Sci (Weinh)
The study reports the first copper‐catalyzed carbonylative C(sp3)─H bond synthesis of flavone using CO2 as the C1 source. Various aryl iodides and 2‐hydroxyacetophenones tolerated well and transformed into flavone with moderate to good yields. 13C‐labeled flavones are successfully synthesized using [13C]‐CO2, demonstrating significant inhibitor ...

Biosynthesis of Ephedrine Initiated by Pyridoxal Phosphate-Dependent Formation of Cathinone. [PDF]

open access: yesChembiochem
An alternative pathway to ephedra alkaloids via (S)–cathinone is investigated in plants. This pathway circumvents the formation of 1‐phenylpropane‐1,2‐dione as an intermediate, which has been part of the predominantly postulated biosynthetic pathway for the last decades. This alternative pathway involves an enzymatic pyridoxal phosphate (PLP)‐dependent

Reaction Engineering for Asymmetric R‐/S‐PAC Synthesis With Ephedrine or Pseudoephedrine Dehydrogenase in Pickering Emulsion [PDF]

open access: yesEng Life Sci
ABSTRACT The synthesis of enantiopure α‐hydroxy ketones, particularly R‐ and S‐phenylacetylcarbinol (PAC), represents an important process in the pharmaceutical industry, serving as a pivotal step in the production of drugs. Recently, two novel enzymes, ephedrine dehydrogenase (EDH) and pseudoephedrine dehydrogenase (PseDH), have been described.

Molecular diagnostics in tuberculosis [PDF]

open access: yes, 2005
Molecular diagnostics in tuberculosis has enabled rapid detection of Mycobacterium tuberculosis complex in clinical specimens, identification of mycobacterial species, detection of drug resistance, and typing for epidemiological investigation.

Stereoselective synthesis of (1S,2S)-1-phenylpropane-1,2-diol by cell-free extract of Lactobacillus brevis

open access: yesGreen Processing and Synthesis, 2016
In this study Lactobacillus brevis cells were cultivated and then disrupted using various cell disruption methods to obtain maximal nicotinamide adenine dinucleotide phosphate (NADP(H))-dependent alcohol dehydrogenase (ADH) activity in cell-free extract.

The effect of lignin content and lignin modification on Norway spruce wood properties and decay resistance [PDF]

open access: yes, 2008
Three different Norway spruce cutting clones growing in three environments with different soil and climatic conditions were studied. The purpose was to follow variation in the radial growth rate, wood properties and lignin content and to modify wood ...
