Abstract
The co-immobilized enzymes and cofactors onto porous microparticles work as self-sufficient heterogeneous biocatalysts whose catalytic activity can be easily monitored by means of the cofactors autofluorescence. The reduction step of some cofactors as NAD+ and FAD+ to NADH and FADH2, respectively, involves an increase of its autofluorescence. This phenomenon is harnessed to image and analyze the enzymatic reactions catalyzed by cofactor-dependent enzymes at real time and single-particle level during the operational process. Due to the universality and highly accessibility of fluorescence microscopy, the strategy described here allows a straightforward and more accurate analysis at micro-scale of heterogeneous biocatalysts. These studies promote and support the rational design and optimization of biocatalysts toward highly efficient heterogeneous biocatalytic reactions.

Abstract
Multiple enzyme systems are being increasingly used for their high-efficiency and co-immobilization is a key technology to lower the cost and improve the stability of enzymes. In this study, poly glycidyl methacrylate (PGMA) spheres were synthesized using suspension polymerization, and were used as a support to co-immobilize glucose oxidase (GOx) and catalase (CAT). Surface modification was carried out via a combination of plasma and amination to promote the properties of the catalyzer. The co-immobilized enzymes showed a more extensive range of optimum pH and temperature from 5.5 to 7.5 and 25 to 40°C, respectively, compared to free enzymes. Furthermore, the maximum activity and protein adsorption quantity of the co-immobilized enzymes reached 25.98 U/g and 6.07 mg/g, respectively. The enzymatic activity of the co-immobilized enzymes was maintained at ~70% after storage for 5 days and at 82% after three consecutive cycles, indicating that the immobilized material could be applied industrially.

Abstract
Unspecific peroxygenases (UPOs) are highly promiscuous biocatalyst with self-sufficient mono(per)oxygenase activity. A laboratory-evolved UPO secreted by yeast was covalently immobilized in activated carriers through one-point attachment. In order to maintain the desired orientation without compromising the enzyme’s activity, the S221C mutation was introduced at the surface of the enzyme, enabling a single disulfide bridge to be established between the support and the protein. Fluorescence confocal microscopy demonstrated the homogeneous distribution of the enzyme, regardless of the chemical nature of the carrier. This immobilized biocatalyst was characterized biochemically opening an exciting avenue for research into applied synthetic chemistry.

Abstract
Pollution of polycyclic aromatic hydrocarbons (PAHs) has drawn much attention around the world. Recent years have seen an upsurge of interest in developing low cost and reliable methods for the detection and precise determination of Polycyclic Aromatic Hydrocarbons (PAHs), because of their carcinogenicity and toxicity. A comprehensive review focusing on sources, accumulation and toxicity of Polycyclic Aromatic hydrocarbons is presented. The review also highlights the current best practices for analysis of PAHs and discus in details the potential cancer risk assessment of Human risk exposure to PAH via three pathways. There is an increased need for laboratories in developing countries to determine such class of chemicals. A major focus revealed the need for low cost method that can be easily implemented such as Dispersive liquid–liquid micro-extraction.

Abstract
In this study, three different approaches for the covalent immobilisation of the horseradish peroxidase (HRP) onto epoxy-activated acrylic polymers (EupergitC) were explored for the first time, direct HRP binding to the polymers via their oxirane groups, HRP binding to the polymers via a spacer made from adipic dihydrazide, and HRP binding to hydrazido polymer surfaces through the enzyme carbohydrate moiety previously modified by periodate oxidation. The periodate-mediated covalent immobilisation of the HRP on hydrazido EupergitC was found to be the most effective method for the preparation of biocatalysts. In this case, a maximum value of the immobilised enzyme activity of 127 U/g(support) was found using an enzyme loading on the support of 35.2mg/g(support). The free and the immobilised HRP were used to study the elimination of phenol in two batch reactors. As expected, the activity of the immobilised enzyme was lower than the activity of the free enzyme. Around 85% of enzyme activity is lost during the immobilisation. However, the reaction using immobilised enzyme showed that it was possible to reach high degrees of phenol removal (around 50%) using about one hundredth of the enzyme used in the soluble form.
