Opis:
This research aimed to measure the impact of provenance on the yield, chemical profile and antimicrobial activity of Rosmarinus officinalis essential oil (EO) collected from cultivated and wild plants from two different regions in Morocco (Fez and Figuig). The chemical composition analysis was accomplished utilizing the GC-MS techniques. Sixteen compounds were identified in the EO of both samples, dominated by 1,8-cineole (32.18%), camphor (16.20%) and α-pinene (15.40%) in cultivated type. The α-pinene (51.19) presents the majority compound in the rosemary samples collected from the wild populations.The antimicrobial activity was investigated by using the broth dilution methods against yeast, four bacterial strains and two molds. Rosemary aerial part provided EO with the highest yield and comes from Figuig. The GC-MS analysis demonstrated the existence of two chemotypes of oils: α-pinene as well as 1,8-cineole/camphor/α-pinene. Both EOs showed good antimicrobial activity against all microbial strains. The essential oil produced by Fez plants was the most effective against the selected microorganisms having MIC values of 0.315–2.5 mg/L.

Opis:
In this study, the effectiveness of using natural bio-coagulants and bio-flocculants to treat textile wastewater through the coagulation-flocculation method was examined. These bio-based agents have several advantages over chemical agents, including biodegradability, natural abundance, low toxicity, and low cost. A bio-coagulant (holm oak acorn (HOA)) and a bio-flocculant (cactus juice) were used to investigate the capacity for turbidity removal and decolorization of textile wastewater. The UV spectrophotometer was used to characterize the discharges before and after treatment, and the chemical oxygen demand (COD) and biological oxygen demand (BOD5) levels were calculated. Box-Behnken design (BBD) coupled with response surface methodology (RSM) were utilized to optimize the process and reduce turbidity and decolorization in textile wastewater. The obtained results show that under the optimal conditions (0.5 g•L-1 of HOA, 15 mL•L-1 of cactus juice, and a pH of 7), decolorization and turbidity removal were achieved at 69% and 90%, respectively. This study demonstrates the potential of using bio-coagulants and bio-flocculants in the treatment of textile wastewater.

Opis:
In the present review article, a soil from the region of Fez-Sefrou Morocco was screened for some physicochemical characteristics using the Plackett-Burman model in order to determine the most important factors that promote its fertility. Five independent variables were selected: pH, electrical conductivity, humidity, organic matter, and C/N ratio. These variables were evaluated by statistical analysis, based on their significance, the value of the coefficient of determination and the Pareto chart. The results suggest that humidity and C/N ratio have an influence with a high level of confidence, while the other three show no significant effect on the content of nutrients in the soil. The analysis of the R2 variance value also showed that the models used for prediction were large and significant factors (p less than 0.05). Pareto chart plots for each response and its characteristics provided accurate data to select well-fitting variables for further optimization.
