Preparation and modification of chitosan particles for Rhizomucor miehei lipase immobilization

Biochemical Engineering Journal, 2011
Chitosan particles, suitable as immobilization support, were prepared by precipitation and modified by reductive amination in order to graft linear aliphatic chains of 12 carbon atoms to their native amine groups. Their physical characterization was performed by different techniques: differential scanning calorimetry (DSC), X-ray diffraction (XRD ...

Enzymatic Knoevenagel condensation in dual‐functionalized water‐mimicking ionic liquids and tertiary amide solvents

Journal of Chemical Technology &Biotechnology, Volume 99, Issue 4, Page 780-787, April 2024.
Abstract BACKGROUND Knoevenagel condensation is an important tool for building carbon–carbon (CC) bonds, especially when catalyzed by enzymes to enable a potentially high chemo‐, regio‐ and/or stereoselectivity. Although many Knoevenagel condensation reactions are carried out in aqueous solutions, insoluble hydrophobic substrates often lead to poor ...

Transesterification of Palm Olein by Immobilised Microbial Lipases [PDF]

, 1996
Enzymatic transesterification of palm olein in organic solvent was studied. The enzyme was first immobilised to celite, lyophilised for 4 h and then added to a reaction medium composed of water-saturated hexane containing of 10% (w/v) palm olein.

The mutual value of histopathology and ITS sequencing in the diagnosis of mucormycosis

Histopathology, Volume 84, Issue 4, Page 702-706, March 2024.
Aims Mucormycosis is a fast‐progressing disease with a high mortality rate. The most important factor determining survival of patients is early and accurate diagnosis. Although histopathology often recognises invasive mould infections at first, histomorphology alone is insufficient in providing an accurate diagnosis.

Glicerólise de óleo de peixe catalisada por lipase comercial de Rhizomucor miehei em meio com surfactante de grau alimentício Glycerolysis of fish oil catalyzed by a commercial lipase from Rhizomucor miehei in reaction media containing food grade surfactant

Química Nova, 2013
Omega-3 enriched partial acylglycerols are beneficial for human health. The aim of this study was to obtain monoacylglycerols (MAG) and diacylglycerols (DAG) by means of glycerolysis of fish oil catalyzed by a lipase from Rhizomucor miehei in the ...

Improved activity of lipase immobilized in microemulsion-based organogels for (R, S)-ketoprofen ester resolution: Long-term stability and reusability

Biotechnology Reports, 2015
Microemulsion-based organogels (MBGs) were effectively employed for the immobilization of four commonly used lipases. During the asymmetric hydrolysis of ketoprofen vinyl ester at 30 °C for 24 h, lipase from Rhizomucor miehei and Mucor javanicus ...

Enzymatic Transesterification Of Palm Olein And Cod Liver Oil By Immobilized Rhizomucor Miehei And Pseudomonas Cepacia Lipases [PDF]

, 2001
Enzymatic transesterification of palm olein (POo) and cod liver oil (CLO) in a solvent free system was studied using immobilized enzymes, with the aim of enriching POo with essential fatty acids/polyunsaturated fatty acids (PUF A) from CLO.

An Organic Solvent-Tolerant Lipase with Both Hydrolytic and Synthetic Activities from the Oleaginous Fungus Mortierella echinosphaera [PDF]

, 2018
Lipase enzymes of the oleaginous fungal group Mortierella are rarely studied. However, considering that most commercial lipases are derived from filamentous fungal sources, their investigation can contribute to the cost-effective development of new ...

Determination of free amino acids in whole-fat Turkish White Brined Cheese produced by animal and microbial milk-clotting enzymes with and without the addition of starter culture

Mljekarstvo, 2012
Coagulating enzymes are essential ingredients for the production of different cheese varieties. The objective of this research was to summarize the effect of rennet type (calf rennet and microbial rennet from Rhizomucor miehei) and starter culture on the
