Currently, the ability to convert raw materials from lignocellulose-rich biomass by traditional methods has many limitations. Therefore, the objective of the thesis is to exploit a variety of biocatalysts (hydrolases) from fungi to efficiently convert lignocellulose-rich biomass from ABP into sugars (C5 and C6) capable of fermenting for bioethanol production. The thesis uses "enzyme cocktail" synergistic catalyst to increase the ability of biological transformation.

Dosimetry is of crucial importance in radiation processing of food. Among others, plastic film has been widely used for dosimetry in radiation therapy since its density is quite similar to the equivalent biological materials. In this study, the depth dose distribution was estimated by using gafchromic film for the purpose of dosimetry in food irradiation.

In this article, we present a process to synthesize new material using urea modified nitrogen TiO2 nano using the hydrometallurgical method. A solution that was a mixture of TiCl4, (NH2)2CO, NH4NO3 and PVA was hydrolyzed at a „suitable‟ temperature and stirring speed and then calcined at 600 oC in 3 hours

Citings of Marshall’s horseshoe bat in areas where it has been previously found have been rare. Prior to this study, little was known about this species. By making use of data and material that were obtained in a series of field surveys conducted between 2006 and 2011, this paper provides an extensive view of the species and presents new findings important to future systematic studies and conservation assessments.

In this study, linoleic acid is obtained by hydrolysis of soybean oil in ethanol/KOH, separation and enrichment using the urea-fatty acid complex formation method for the fractionation of fatty acids. The process involves the formation at 60 ◦C of a homogeneous solution of free fatty acid and urea in 95% ethanol, followed by cooling the resultant urea complex slurry to -5 ◦C and separation by filtration.

Melon shows a broad diversity in fruit morphology and quality, which is still underexploited in breeding programs. The knowledge of the genetic basis of fruit quality traits is important for identifying new alleles that may be introduced in elite material by highly efficient molecular breeding tools.

Why study chemistry in an anatomy and physiology course? The answer is simple. Your entire body is made up of chemicals, thousands of them, continuously interacting with one another at an incredible pace. Although it is possible to study anatomy without much reference to chemistry, chemical reactions underlie all physiological processes—movement, digestion, the pumping of your heart, and even your thoughts. This chapter presents the basic chemistry and biochemistry (the chemistry of living material) you need to understand body functions.

Before we begin to study in detail the structure and activities of genes, and the experimental evidence underlying those concepts, we need a fuller outline of the adventure that lies before us. Thus, in this chapter and in chapter 3, we will fl esh out the brief history of molecular biology presented in chapter 1. In this chapter we will begin this task by considering the behavior of genes as molecules.

Polymerase Chain Reaction is widely held as one of the most important inventions of the 20th century in molecular biology. Small amounts of the genetic material can now be amplified to be able to a identify, manipulate DNA, detect infectious organisms, including the viruses that cause AIDS, hepatitis, tuberculosis, detect genetic variations, including mutations, in human genes and numerous other tasks.

Peptides which should be generated from the neuropeptide FF (NPFF) precursor were identified in a neuronal (human neuroblastoma SH-SY5Y) cell line and in COS-7 cells after transient transfection of the human proNPFFAcDNA and were comparedwith those detected in themouse spinal cord. After reverse-phase high performance liquid chromatogra-phy of soluble material, NPFF-related peptides were im-munodetected with antisera raised against NPFF and identified by using on-line capillary liquid chromatography/ nanospray ion trap tandem mass spectrometry. ...

Structural elucidation of the lipopolysaccharide (LPS) from three nontypeable Haemophilus influenzaeclinical isolates, 1209, 1207 and 1233 was achieved using NMR spectro-scopy and ESI-MS on O-deacylated LPS and core oligo-saccharide (OS) material as well as ESI-MS n on permethylated dephosphorylated OS. It was found that the organisms expressed a tremendous heterogeneous glyco-form mixture resulting from the variable length of the OS chains attached to the common structural element of H.

The cytochromeb559 content was examined in five types of isolated photosystem II D1-D2-cytochromeb559reaction center preparations containing either five or six chlorophylls per reaction center. The reaction center complexes were obtained following isolation procedures that differed in chromatographic column material, washing buffer compo-sition and detergent concentration. Two different types of cytochromeb559assays were performed. The absolute heme content ineachpreparationwas obtainedusing theoxidized-minus-reduced difference extinction coefficient of cyto-chrome b559 at 559 nm. ...

Feruloyl esterases hydrolyse phenolic groups involved in the cross-linking of arabinoxylan to other polymeric structures. This is important for open-ing the cell wall structure making material more accessible to glycoside hydrolases. Here we describe the crystal structure of inactive S133A mutant of type-A feruloyl esterase fromAspergillus niger(AnFaeA) in complex with a feruloylated trisaccharide substrate.

Normally, any ferromagnetic or ferrimagnetic material undergoes a transition to a paramagnetic state above its Curie temperature. Superparamagnetism is different from this standard transition since it occurs below the Curie temperature of the material. Superparamagnetism occurs in nanoparticles which are single domain. This is possible when their diameter is below 3–50 nm, depending on the materials.

For 30 years, the field of medical device technology has struggled to identify the specifications for optimal biocompatibility. For the vast majority of devices, clinical experience has eventually confirmed that the best performance is achieved when biocom-patibility is equated with biological safety that is materials are selected on the basis of maximizing bioinertness and minimizing toxicity and irritation.

The nano-scale spatial organization of metallic and other inorganic materi-als into 1D objects is a key task in nanotechnology. Nano-scale fibers and tubes are very useful templates for such organization because of their inherent 1D organization. Fibrillar biological molecules and biomolecular assemblies are excellent physical supports on which to organize the inor-ganic material.
