The biotechnological applications use stable and eco-friendly biocatalysts, with good operational properties, reusable easily separable. An efficient method of improving the stability enzymes as biocatalysts may be immobilization. immobilization research objectives are obtaining versatile insoluble enzyme preparations high enzymatic activity, capable catalyzing reactions their natural unnatural...

Gold nanorods (AuNRs) are successfully employed in drug delivery, biosensors, and biotechnologies. Their wide success is due to their unique chemical properties, biocompatibility, easy, cheap versatile synthesis. In this framework, AuNRs were synthetized with the aim obtain strongly hydrophilic nanomaterials, suitable as delivery system. by seed mediated methods two steps. After careful purific...

Halophilic and halo-tolerant bacteria are micro-organisms that living in hyper saline environments. They have many potential several fields life such as Industry agriculture. In this study a total of 17 isolates were obtained from the four ponds Qarun Lake on Nutrient Agar (NA) medium prepared using ponds' water. The 16S rRNA analysis showed our affiliated with groups, Firmicutes (47.06% isolat...

Lipases are the most pliable biocatalyst and bring about a wide range of bioconversion reactions, such as hydrolysis, interesterification, esterification, alcoholysis, acidolysis and aminolysis. Lipases can act on a variety of substrates including natural oils, synthetic triglycerides and esters of fatty acids. They are resistant to solvents and are exploited in a broad spectrum of biotechnolog...

Pyrolysis mass spectrometry is a rapid and high-resolution method for the analysis of otherwise non-volatile material and has been widely applied for discriminating between closely related microbial strains. Recent advances in statistical and neural network methods based on supervised learning have now permitted exploitation of pyrolysis mass spectrometry in the quantitative analysis of many di...

Bioleaching is a proven bioprocess for metal recovery by solution from solid matrices, while a bioprecipitation or biomineralization approach is of potential for biorecovery from solution. Fungi can directly and indirectly mediate the formation of many kinds of minerals, including oxides, phosphates, carbonates and oxalates, as well as elemental forms of metals and metalloids such as Ag, Se and...
