Present research on prebiotics focuses on either polysaccharides or polyphenols. This study compared the individual and combined impact of polysaccharide, quercetin, and gallic acid (GA) treatment on three human faecal strains. In vitro pure culturing and correlation analysis confirmed that the growth of both beneficial microbe B. longum subsp. longum (0.695, 0.205: R2, slope, respectively) and pathogenic C. perfringens (0.712, 0.085: R2, slope, respectively) increased due to polysaccharide treatment, and only GA treatment would inhibit C. perfringens (0.789, –0.165: R2, slope, respectively) growth. In vivo studies also revealed that genome copies of Bifidobacterium increased and C. perfringens decreased in the faeces, when a blend of the three nutrients rather than single polysaccharide or polyphenols were fed to rats. These data suggested that combined prebiotic treatment improved human faecal strain composition better than single treatment.

Our research target was to utilise vine-branch, existing in huge amounts, for energetic purposes. During our experiments, microwave (MW) treatments of different powers (400–1600 W), pressures (1–5 bar), temperatures (120–180 °C), and treatment times (3–30 min) were applied to change the physical condition of vine-branch. After MW, enzymatic hydrolysis (EH) was used (85–100 h, 37 °C). In addition, beside MW, comparisons were made regarding various treatment methods: untreated (UTE), cooking plate (CP), and autoclave (AC), to determine to what extent they affect the final glucose yield. This yield can even further be increased by MW pre-treatment (50 W, 3–30 min, 40 °C) of the enzyme used during the hydrolysis, which reinforces the argument that enzyme activity can be increased by irradiation. A difference of 22.1% was detected among the glucose yield values in untreated and treated enzyme processes.

Diverting household waste from landfill had become a must for EU member states. The mechanical and biological treatment of household wastes is one of the key method to reach this goal. The object of the mechanical handling is to separate the recyclable fraction and transform the non-recyclable part into Refuse Derived Fuel (RDF) for energetic use and produce fraction for biological treatment. Our challenge to identify the ideal technology for RDF production for the North-Balaton Regional Waste Management System, by studying the existing technologies, and emerging needs from the growing market especially for Cement Industry and pyrolitic technologies.

This study was to examine how encapsulated Lactobacillus casei 01 combined with pasteurized longan juice colonized a digestive system by using a simulator of the human intestinal microbial ecosystem. The results showed that encapsulated L. casei 01 and longan juice stimulated an increase of colon lactobacilli, bifidobacteria, lactic acid and various short-chain fatty acids for which acetate was substantially present in both colons followed by propionate and butyrate. On the contrary, the treatments triggered off the reduction of faecal coliforms, clostridia, and total anaerobes. To sum up, the denaturing-gradient-gel electrophoresis supported that treatment conditions stimulated diversities of bacteria communities occurring in both colons.
