dead yeast cells are an abundant residue of the brazilian ethanol industry and the industries still don’t have a proper or desirable destiny for all these cells, which means tons of vitamins and proteins that have not a major end. in the other hand, heavy metal residues are a problem, especially for leather industry, where brazil is also a great producer. in this work, dead yeast cells were us...

microbial cells have been successfully used as biosorbents to remove heavy metals from wastewater. in some cases, dead cells appear to offer more advantages than living cells in the removal and recovery of heavy metal ions from industrial wastewater. maintaining higher biosorption capability and understanding the biosorption properties of dead cells are the keys to heavy metal removal and recov...

The overall goal of this study was to fabricate multifunctional core-shell microcapsules with biological cells encapsulated within the polymer shell. Biocompatible temperature responsive microcapsules comprised of silicone oil droplets (multicores) and yeast cells embedded in a polymer matrix (shell) were prepared using a novel microarray approach. The cross-linked polymer shell and silicone mu...

With the need to obtain new methods protect seed material from Ditylenchus dipsaci (KĂźhn, 1857) nematodes, a study was conducted evaluate nematicidal effects of several plants' essential oils on mortality D. dipsaci. Tests were performed under in vitro conditions; concentration 2 000 ppm tested, nematodes added into diluted oils, and numbers living/dead scored after 4 24 h. The results show si...

In Latin America, Ecuador, Colombia, and Honduras have the highest oil palm production, diseases that quickly spread in plantations affect this production. That is why it important for these countries to control over plagues. Using pesticides produces environmental pollution respiratory problems workers. Therefore, necessary apply precision farming technologies can prevent from having use when ...

In the present paper, chemical shift imaging techniques are applied to quantitative in vivo evaluation of fat and water content in interscapular brown adipose tissue (BAT). The experiments have been carried out on five female Sprague-Dawley rats after calibration and testing with suitable phantoms containing known amounts of water and oil. We found that, in the interscapular BAT, the fat is abo...
