Abstract Slow-release urea fertilisers have been shown to present acceptable values for plant yield and mitigate the harmful effect of soil emission gases. This study synthesises a slow-release fertiliser containing fumed-nanosilica, nanofibrillated cellulose as well as sodium alginate as a urea carrier to analyse the growth parameters of Eucalyptus urograndis seedlings and potential emission of soil gases, N2O, CH4, CO2 and ammonia volatilisation. The developed supraparticles, arranged layered nanopar- ticle structure, presented a decrease in the normal nitrogen content of urea of 19%, which is attributed to the binding of this element. A good electrostatic interaction between the elements was confirmed by the FTIR with 20% of nitrogen content from its chemical composition and an increase in thermal degradation of the main components when synthesised. The profile of urea release presented to be as first-order with 85% of this compound was released only after 60 days. These characteristics led to statistically increased growth of Eucalyptus seedlings compared to the controls, which improves with higher dosages of urea. Values of biomass and characteristics of the plant were used for principal component analysis which resulted in good cluster formation based on the upward concentration of urea added to the plant. Nevertheless, flux gases were statistically higher for certain time periods on lower urea particle concentration, while increased concentration presented N 2 O emissions within standard rates with no significant variation in the other measured gases, which was attributed to the soil microbial targeted consumption. Therefore, this material can be beneficial in the agriculture industry.

This work aimed to evaluate the bioactivity of 3-(p-chlorophenyl)thio citronellal against planktonic and biofilm cells of S. aureus and its use in biodegradable films. 3-(p-chlorophenyl)thio citronellal demonstrated antimicrobial activity against planktonic (MIC=62.5 ± 0.5 μg.mL−1) and biofilm cells of S. aureus. Regarding barley starch films containing 3-(p-chlorophenyl)thio citronellal, after 4 h of contact there was a difference of 5 log CFU.mL−1 in relation to control film (without additives). The films prepared with 3-(p-chlorophenyl)thio citronellal and citral (its precursor) were more opaque and had lower tensile strength than the control film. However, the addition of the 3-(p-chlorophenyl)thio citronellal in the film had lower effect on the water solubility and tensile strength than the addition of citral. 3-(p-chlorophenyl)thio citronellal have activity against planktonic and biofilm cells of S. aureus and could be applied in biodegradable films as an alternative to inhibit the microbial growth on the surface of food, enhancing food safety. |
