Black rot, caused by Xanthomonas campestris pv. campestris, is one of the most important diseases of cruciferous crops which causes significant yield losses. Biological control of black rot by microbial biocontrol agents represents a promising alternative to chemical treatments and good agricultural practices which show only limited success. This study was carried out to assess a potential of different antagonists, including genera Bacillus, Pseudomonas, Lactobacillus, Streptomyces, Saccharomyces and Trichoderma, for biological control of black rot. Cultivation broth samples and their filtrates were examined against seven Xanthomonas campestris strains, isolated from diseased cruciferous plants, using the diffusion-disc method. Bacillus velezensis has showed the highest inhibition zone diameter of 35.62?3.76 mm. Afterwards different combinations of carbon and nitrogen sources were used in cultivation medium to maximize antagonistic activity of Bacillus velezensis. The best combinations were glycerol and yeast extract, lactose and peptone, as well as sucrose and yeast extract, suggesting the potential of biodiesel, dairy and sugar industry effluents in the production of bioactive compounds effective against the black rot pathogen. Validation experiment was performed in a laboratory-scale bioreactor, in order to investigate bioprocess kinetics of biomass growth and carbon source consumption, using cultivation medium containing the optimal carbon and nitrogen source.

“…Furthermore, the promotion of single cell protein (SCP) production by kefir was revealed using orange juice containing orange pulp (Plessas et al., 2008) and orange peels were used for immobilization of Saccharomyces cerevisiae cells for successful alcoholic fermentation (Plessas et al., 2007). Moreover, as was recently reported an enhanced green production of xanthan gum was achieved by utilizing orange peels (Mohsina et al., 2018). Agro-industrial citrus side streams include (i) the discarded surplus of citrus fruits, (ii) the liquid effluent of citrus juices industry and (iii) its citrus peel.…”

The current investigation reveals new findings concerning the substantial promotional activity of orange juice, orange peel and molasses on whey fermentation using single cell culture of kefir microflora. Specifically, the addition in whey of only 1 % v/v orange juice or 1% v/v molasses - 4% w/v orange peel reduced the fermentation time to 10 from 70 hours. But the lowest fermentation time (9 h) was observed when a composite biocatalyst consisted of cells entrapped with orange peel in corn starch gel was used, where also the highest 14 C-labeled lactose uptake rate by kefir was recorded. Bio-ethanol concentrations were increased using all the aforementioned promoters too and volatile byproducts such as esters were raised during the whey-orange juice mixtures fermentations, while terpenes by composite biocatalyst. The findings could be the base for new research projects for the rapid production of novel food stuffs and chemicals using whey as raw material.

“…New peaks appeared only in the FTIR spectra of the orange juice stored in the active package at 4 °C after 4 days and 9 days of storage, respectively. Signals at 2,864 and 2,936 cm −1 are assigned to the axial deformation of C‐H due to the absorption of symmetrical and asymmetrical stretching of C‐H (Mohsina et al, ; Saberian, Hamidi‐Esfahani, Gavlighi, & Barzegar, ). The signal is strong for the sample after 4 days of storage and weak for that stored 9 days.…”

An active package from cardboard coated with titanium dioxide was designed for storage of fresh prepared orange juice. The organoleptical changes of the orange juice were statistically significant and revealed the preservation role of the active cardboard at 4 C. Statistically significant positive effect on the reducing the rate of ascorbic acid degradation and on the increasing the catalase activity, respectively, was generated by coating TiO 2 , revealing that the semiconductor favors the preservation of the orange juice during storage. FTIR spectra revealed new compounds in the juice stored in the active package at 4 C, but these substances has no significantly affected the characteristics of the juice. This study reveals that the TiO 2 -cardboard is a promising solution to package fresh prepared orange juice and to store it in safety conditions at 4 C for 7 days. The mechanism that ensure the preservation of juice as a result of TiO 2 particles photoactivity was discussed. Practical applicationsThe study report about a new type of active package made from cardboard coated with TiO 2 designed for storage of fresh prepared orange juice. The results showed the statistically significant and positive influence of TiO 2 on preserving the organoleptical parameters, ascorbic acid content and catalase activity of the orange juice during storage for 9 days. This study reveals that the TiO 2 -cardboard is a promising solution to package fresh prepared orange juice and to store it in safety conditions at 4 C for 7 days.
