“…A good fitted model should have a minimum R 2 of 80% an R 2 -value that is greater than 0.9 proves a very high degree of correlation [40]. The results of data analysis showed that the R 2 values of the models are 0.96, 0.94, and 0.98 respectively for VMA1, VMA7 and VMAO.…”

This study aimed to investigate optimal fermentation conditions of biological acetic acid fermentation for vinegar production. Optimization was performed on 3 acetic acid bacteria strains namely VMA1, VMA7 and VMAO using Response Surface Methodology (RSM). A Box-Behnken-Design (BBD) was achieved with three different independent process parameters involving: fermentation temperature, original alcohol concentration and original acetic acid concentration and one dependent variable (acetic acid yield). The results showed that the mathematical models describe correctly the relationship between responses and factors (F values of the models (p < 0.05), R 2 (coefficient of correlation) respectively 0.96, 0.94, 0.98, and adjusted R 2 0.95, 0.92, 0.98).The maximum acidity was obtained respectively at fermentation temperatures, original alcohol concentrations and original acetic acid concentrations ranging from [37.5˚C -45˚C], [16% -20% (v/v)], [1.5% -2% (w/v)] for VMA1, [40˚C -45˚C], [14.5% -20% (v/v)], [1.7% -2% (w/v)] for VMA7 and [42˚C -45˚C], [17% -20% (v/v)], [1.5% -2% (w/v)] for VMAO. The use of these acetic strains in the production of vinegar may seriously lead to a decrease or even an ablation of the costs related to the cooling of bioreactors especially in warm and hot countries, in the context of global warming.

Liquid phase microextraction is a state-of-the-art micro-analytical work with numerous advantages documented in the scientific literature. One of the most intriguing subclasses is the CO 2 -effervescence assisted dispersive liquid−liquid microextraction method. Working theory was based on an acid-based reaction involving a proton donor and a carbon dioxide source. The paper outlines the considerations regarding the microextraction performance that can change in terms of physical, chemical properties, and its application for environmental sample analysis. A wide range of the developed and applied novel methods clearly indicates that CO 2 -effervescence is still in demand among researchers looking for new achievements in green analytical chemistry. This review focuses on the method application for the extraction and preconcentration of different classes of micropollutants (organic or inorganic) in environmental waters. New breakthroughs in the microextraction process show enhanced performance of the system in terms of sensitivity, accuracy, precision and the attempt to reduce extraction steps during separation or retrieval processes for low concentrations of analytes. Future direction refers to the improvement of green parameters in the microextraction, use of extracting agents as co-dispersers (solid or liquid), removal of elution dependency in solvents by the use of super-paramagnetic properties, etc. The success stories of the method development are widely documented in the literature. This microextraction technique will continue to serve as a reliable tool for the determination of micropollutants in environmental samples.
