Biogeneration of 1-octen-3-ol by lipoxygenase and hydroperoxide lyase activities of Agaricus bisporus
2001
Abstract The biogeneration of 1-octen-3-ol by lipoxygenase and associated hydroperoxide lyase activities of a homogenate of the cultivated mushroom Agaricus bisporus was investigated using linoleic acid as a substrate. The optimal substrate and protein concentrations were 1.5 mM and 1.5 mg ml −1 , respectively. The V max value for the enzymic coupled reaction lipoxygenase–hydroperoxide lyase was 6 μg of 1-octen-3-ol ml −1 min −1 , with a K m value of 0.3×10 −3 M. The highest enzymic activity was observed in the presence of pure oxygen (22.9 μg of 1-octen-3-ol ml −1 ), with a bioconversion yield of 36%. The production of 380 μg 1-octen-3-ol per g of mushroom homogenate was demonstrated using…
Evaluation of pulsed electric field-assisted extraction on the microstructure and recovery of nutrients and bioactive compounds from mushroom (Agaric…
2022
Pulsed electric field (PEF) is a sustainable innovative technology that allows for the recovery of nutrients and bioactive compounds from vegetable matrices. A. bisporus was chosen for its nutritional value and the effect of PEF pretreatment was evaluated using different conditions of electric field (2–3 kV/cm), specific energy (50–200 kJ/kg) and extraction time (0–6 h) to obtain the best conditions for nutrient and bioactive compound extraction. Spectrophotometric methods were used to evaluate the different compounds, along with an analysis of mineral content by inductively coupled plasma mass spectrometry (ICP-MS) and the surface was evaluated using scanning electron microscopy (SEM). In …
First Report of Agaricus aridicola in Saudi Arabia and Ecological Notes on Agaricus bisporus
2015
Agaricus aridicola is reported for the first time from Saudi Arabia while Agaricus bisporus is a new record for Northern region of Saudi Arabia. This study includes notes on taxonomy, ecology and distribution of both the species. It was also reported that the habitat of A. aridicola and A. bisporus are characterized by calcareous sandy soil, poor in organic matter, with presence of little amount of salinity.
