Nanotechnology is quickly becoming one of the most essential and transformative areas science. Physical, chemical, mechanical, biological approaches are all used to create nanoparticles. Plants or microorganisms frequently in methods metal ion reduction because they clean, nontoxic, safe, biocompatible, ecologically friendly. Fourir transform infra-red spectroscopy (FT–IR), scaning electron mic...

This study aimed to facilitate efficient arsenic detoxification by inducing the microbial methylation of inorganic arsenic. Recombinant Escherichia coli strains K31 was transformed overexpress methyltransferase, and evaluated using enzyme extracted from strain. To ensure continuous reactions maintaining enzymatic activity, immobilized in microcapsules (MC) catalyze The total yield methylated or...

Alkaline Protease enzyme produced from Bacillus Licheniformis PTCC1331 in optimum Condition(Temperature 37 ?C, 150 rpm, PH=10), is immobilized in different concentrations of Sodium Alginate using entrapment method, to increase its thermal resistance in detergents, and its activity is measured thereafter. Maximum enzymatic activity of 46 was obtained in 2%w/v Sodium alginate solution. Investiga...

Tendon never restores the complete biological and mechanical properties after healing. Bone marrow and recently adipose tissue have been used as the sources of mesenchymal stem cells, which have been proven to enhance tendon healing. Stromal vascular fraction (SVF), derived from adipose tissue by an enzymatic digestion, represents an alternative source of multipotent cells, which undergo differ...

Enzymatic catalysis has been pursued extensively in a wide range of important chemical processes for their unparalleled selectivity and mild reaction conditions. However, enzymes are usually costly and easy to inactivate in their free forms. Immobilization is the key to optimizing the in-service performance of an enzyme in industrial processes, particularly in the field of non-aqueous phase cat...

The use of enzymes as industrial biocatalysts is currently a solution for many problems of modern organic chemistry, which tries to carry out the most complex reactions under the rules of green chemistry [1]. In this context, enzyme immobilization is a critical point for the implementation of many processes [2]. This technique has been developed to obtain a heterogeneous biocatalyst, and thereb...

Enzymes have been widely studied for their excellent efficiency, selectivity and environmentally benign nature. However, the development of biocatalytic applications is severely limited by lack stability reusability. Nanostructured materials demonstrated as efficient hosts immobilization enzyme due to large surface areas well higher activities long-term stability. Furthermore, nanomaterials wit...

Biofuel cells have been widely used to generate bioelectricity. Early biofuel cells employ a semi-permeable membrane to separate the anodic and cathodic compartments. The impact of different membrane materials and compositions has also been explored. Some membrane materials are employed strictly as membrane separators, while some have gained significant attention in the immobilization of enzyme...

BACKGROUND Immobilization of microbial cells is an important strategy for the efficient use of whole-cell catalysts because it simplifies product separation, enables the cell concentration to be increased, stabilizes enzymatic activity, and permits repeated or continuous biocatalyst use. However, conventional immobilization methods have practical limitations, such as limited mass transfer in th...
