Abstract
2-Nonenal is a long-chain aliphatic aldehyde containing nine carbons and an unsaturated bond. 2-Nonenal is the primary cause of odor associated with aging, with an unpleasant greasy and grassy odor. Lysosome, mitochondria, and peroxisome are significant organelles in eukaryotic cells that contain various hydrolases that degrade biomolecules. Proteins in mitochondria and peroxisome also contain aldehyde dehydrogenase. We performed trans-2-nonenal treatment using lysosomal-related enzymes extracted from hen egg white (HEW). As trans-2-nonenal is more structurally stable than cis-2-nonenal, it was selected as the target aldehyde. HEW contains various biologically active proteins and materials such as albumin, ovotransferrin, lysosome, peroxisome, and mitochondria. Here, complementary experiments were conducted to evaluate the role of lysosomal-related enzymes in the treatment of trans-2-nonenal. The activity of lysosomal-related enzymes was confirmed via antimicrobial test against E. coli. HPLC analysis was used to determine the reduction of trans-2-nonenal. The trans-2-nonenal treatment depended on the reaction time and enzyme concentration. Materials considered as an intermediate from trans-2-nonenal treatment were detected by GC/MS spectrometer. Under acidic conditions (pH 6), lysosomal-related enzymes were the most efficient in the treatment of trans-2-nonenal. Furthermore, based on differential pH testing, we found the conditions under which all the 50 ppm trans-2-nonenal was removed. Therefore, our results suggest that the lysosomal-related enzymes reduced trans-2-nonenal, suggesting clinical application as anti-aging deodorants.

Abstract
Human health is recently affected by several factors in which food contamination is one of the most dangerous elements that damage directly on our bodies. In this study, we provided a novel approach for the rapid detection of Salmonella sp. at the molecular level using the response of Saccharomyces cerevisiae's vacuoles. First, an augmentation of vacuoles intensity was observed by confocal microscopy after treating Salmonella strains with yeast cells. Second, the vacuolar enzymes were isolated and then analyzed by two-dimensional electrophoresis for the screening of specific biomarkers. After that, various recombinant yeasts containing exclusive biomarkers were constructed by fusing these biomarkers with several fluorescent proteins. Finally, the recombinant strains showed the ability to detect Salmonella strains specifically by appropriate fluorescent signals from 20 CFU/mL after 15 Min of exposure.

Abstract
Saccharomyces cerevisiae is the simplest and a favorite eukaryotic system that contains lysosome and thus, is a suitable organism for monitoring some toxic effects in environmental pollution. In this study, S. cerevisiae was transformed with two recombinant plasmids. Sporulation-specific glycoamylase (SGA1), which was upregulated in response to arsenic, was fused with the blue fluorescent protein (BFP) for the construction of an oxidative stress-causing chemicals sensor. Additionally, thioredoxin (TRX2), a protein overexpressed exclusively under tetracycline's influence, fused with the cyan fluorescent protein (CFP) to create a detector for this kind of chemical. In summary, we developed two recombinant S. cerevisiae that facilitate the detection of both kinds of toxic chemicals, specifically visualized by different color indicators.
