Biocomposites based on collagen and keratin with properties for agriculture and industrie applications

vegetation, to cover the silicves and to prevent the dehiscence. In these reference works, only the collagen hydrolysates from fish skin has been tested also in rapeseed germination. The present papers refer to application of collagen-based products from bovine skin and wool keratin to stimulate germination of rape seeds and plants nutrition in the start of vegetation. Correlation of this information with other specific data (e.g. with soil characteristics) can lead to the initiation of high-performance rapeseed cultures, reducing the contribution of synthetic

Optical properties of translucent zirconia: A review of the literature

favorable mechanical properties and esthetic performance at 0,5-1mm ( 67 ). Conventional zirconia has excellent strength, but its color is white and opaque as chalk; to individualize the color and translucency of a natural tooth, it is required important post-milling work, like stratification of feldspathic porcelain. The introducing of translucent zirconia blocks, which are directly milled into monolithic restorations has been one of the most challenging innovation of the last decade in dentistry. In addition, the translucent zirconia discs are provided in a high

Real time human micro-organisms biotyping based on Water-Assisted Laser Desorption/Ionization

and published ( 18 , 20 ). The identifications were performed directly on the tissue by doing a full scan first to verify the presence of the targeted masses. Then after switching to MS/MS mode, they were subjected to collision-induced dissociation (CID) in the transfer cell with respectively 20 and 35 V. The resulting spectra were annotated manually, and assignments were verified by interrogating the high accuracy mass measurements of the precursor ions using the LipidsMap database.

Lachish River event monitored for toxicity using bioluminescent reporter organisms

waste ( 10 ). The river is being monitored for coliform concentration weekly by the Ashdod-Yavne regional association for environmental protection. If any cause for alarm does occur, the association tests the contaminated water using conventional analytical approaches. Examples of these techniques are total organic carbon (TOC), biological oxygen demand (BOD), chemical oxygen demand (COD), TSS and coliforms. In addition to that, gas chromatography (GC), inductively-coupled plasma mass spectrometry (ICP-MS) and high-performance liquid chromatography (HPLC), which are

Solid-state fermentation of paper sludge to obtain spores of the fungus Trichoderma asperellum

solubility, while very high water content decreased interparticle airspace causing a lower oxygen transfer, phenomenon previously observed ( 27 ), determining that increases in water content in solid cultures, improved the performance of the anaerobic bacterium C. thermocellum . In this way, it was decided to continue this work using a water content of 60% to avoid limitations due to water excess or defect. It has been determined the feasibility of SSF using PS as substrate to obtain Trichoderma spores ( 23 ). However, these processes gave lower yields than those

Advanced approaches to produce polyhydroxyalkanoate (PHA) biopolyesters in a sustainable and economic fashion

: degree of polymerization; *: chiral carbon atom in most PHA building blocks. The improvement of large-scale productivity, cost efficiency, and strain performance demands optimization procedures of different process steps. This includes the quest for new wild type and genetically modified microbes, development of a process design adapted to the kinetic characteristics PHA production, and ecologically benign and efficient techniques for separation of PHA and residual non-PHA biomass. Only the synopsis of these steps allows ecologically feasible and sustainable
