Degradation Products of Polychlorinated Biphenyls and Their In Vitro Transformation by Ligninolytic Fungi

open access: yesToxics, 2021
Metabolites of polychlorinated biphenyls (PCBs)—hydroxylated PCBs (OH-PCBs), chlorobenzyl alcohols (CB-OHs), and chlorobenzaldehydes (CB-CHOs)—were incubated in vitro with the extracellular liquid of Pleurotus ostreatus, which contains mainly laccase and

Extracellular cellulolytic complexes production by microscopic fungi [PDF]

open access: yesBiotechnologia acta, 2015
The aim of this work was to screen and to study the effect of inducers on the synthesis of the cellulolytic enzyme complexes by microscopic fungi. Cellulolytic and xylanolytic activities were determined by reducing sugar with DNS reagent, and β-glucosidase activity by pNPG hydrolysis.

Effects of Flavobacterium psychrophilum extracellular products and lipopolysaccharide antigens on the antioxidant enzyme system activity of rainbow trout (Oncorhynchus mykiss) fry

open access: yesMacedonian Journal of Chemistry and Chemical Engineering, 2022
The aim of this study was to investigate the response of different doses of lipopolysaccharide (LPS) and extracellular product (ECP) antigens (25, 50, 100, 250, and 500 µg) obtained from Flavobacterium psychrophilum to changes in oxidative stress ...

Activation of the plant mevalonate pathway by extracellular ATP

open access: yesNature Communications, 2022
Products of the mevalonate pathway support plant development. Here the authors show that the extracellular ATP receptor P2K1 phosphorylates mevalonate kinase and this affects the mevalonate pathway.

Isolation and characterization of filamentous fungi capable of degrading the mycotoxin patulin

open access: yesMicrobiologyOpen, 2023
Patulin is a toxic secondary metabolite synthesized by various fungal strains. This mycotoxin is generally toxic to microorganisms as well as mammals due to its reactivity with the important cellular antioxidant glutathione.

Critical evaluation of heat extraction temperature on soluble microbial products (SMP) and extracellular polymeric substances (EPS) quantification in wastewater processes

open access: yesWater Science and Technology, 2022
While soluble microbial products (SMP) and extracellular polymeric substances (EPS) in wastewater bioprocesses have been widely studied, a lack of standard quantification procedures make it difficult to compare results between studies.

Extracellular neuraminidase production by group B streptococci [PDF]

open access: yesInfection and Immunity, 1977
Neuraminidase (sialidase) activity in concentrated culture filtrates of group B streptococci was measured with bovine submaxillary mucin as substrate. Group B streptococcal neuraminidase was not active on human alpha-1 acid glycoprotein and did not show increased activity on bovine submaxillary mucin that had been O-deacetylated by alkaline treatment ...
