Reliable and accurate in situ sensors capable of detecting quantifying troublesome marine biofilms on metallic surfaces are increasingly necessary. A 0.2 mm diameter gold electrochemical sensor was fully characterized using cyclic voltammetry abiotic biotic artificial seawater media within a continuous culture flow cell to detect the growth development an aerobic Pseudoalteromonas sp. biofilm. ...

The incidence and intensity of bushfires is increasing due to climate change, resulting in a greater risk smoke taint development wine. In this study, smoke-tainted non-smoke-tainted wines were subjected treatments using activated carbon with/without the addition cleaving enzyme treatment hydrolyze glycoconjugates. Chemical measurements volatile aroma compounds assessed for each treatment, with...

Abstract ( R ) - mandelic acid is an industrially important chemical, especially used for producing antibiotics. Its chemical synthesis often uses highly toxic cyanide to produce its racemic form, followed by kinetic resolution with 50% maximum yield. Here we report a green and sustainable biocatalytic method )-mandelic from easily available styrene, biobased L- phenylalanine, renewable feedsto...

Enzymatic approaches for locating alkylation adducts at single-base resolution in DNA could enable new technologies for understanding carcinogenesis and supporting personalized chemotherapy. Artificial nucleotides that specifically pair with alkylated bases offer a possible strategy for recognition and amplification of adducted DNA, and adduct-templated incorporation of an artificial nucleotide...

Glycolate dehydrogenase activity was detected in cell-free extracts of Oscillatoria sp. prepared by osmotic lysis of spheroplasts in 0.05 m potassium phosphate buffer, pH 7.5, containing 0.3 m mannitol. Most of the enzyme activity was found in a particulate fraction and localized in the photosynthetic lamellae after centrifugation in a discontinuous sucrose density gradient. Enzyme activity was...

Streptokinase is a potent fibrinolytic agent which is widely used in treatment of deep vein thrombosis (DVT), pulmonary embolism (PE) and acute myocardial infarction (MI). Major limitation of this enzyme is its short biological half-life in the blood stream. Our previous report showed that complexing streptokinase with chitosan could be a solution to overcome this limitation. The aim of this re...
