- Abstract:
- ... An industrial process for black table olives fermentation was followed in order to study the effect of immobilized halophile culture and the initial halophile culture concentration in combination with temperature for a period of 30 days. For comparison, three types of batch fermentation were investigated: (a) fermentation with the indigenous microbiota (control), (b) inoculated fermentation with i ...

- Abstract:
- ... Food safety, especially with respect to pesticide-contaminated products, has received considerable attention in recent years. In this study, the effects of food processing steps on pesticide residues in apples were analyzed on the basis of processing factors (PFs) via a chemometric approach. Based on the PFs data, the removal efficiencies of beta-cypermethrin, chlorpyrifos, tebuconazole, acetamipr ...

As alternative antimicrobial and antibiofilm agent selenium nanoparticles (SeNPs) were biosynthesized by treatment of 1 mM SeO2 with the free-cell supernatant of Bacillus licheniformis isolated from food wastes. The biosynthesized SeNPs ...

Acidic hydrolyses of these oligosaccharide mixtures revealed that they were mostly composed of glucose, galactose and mannose. Microbial utilizations of the obtained oligosaccharide mixtures showed that they were able to promote t ...

The procedure is based on coprecipitation of Sn(II) on N-Benzoyl-N,N-diisobutylthiourea without carrier element. While Sn(II) can be quantitatively precipitated on N-Benzoyl-N,N-diisobutylthiourea in the pH range of 8.0–9.0, recovery of Sn(IV) was below 10%. Total tin was determi ...

Pathogenic biofilms that form on food processing equipment/surfaces are of great concern, because these can readily lead to food spoilage, bio-fouling, food-borne illness, and their recalcitrance can result in the acquisition of multi-drug resistance. Currently available coatings do not completely inhibit microbial growth and an increased demand for such coatings means that new products will need ...
