“…The results achieved for both these parameters showed that the biodegradation process was never evident in the first 5 days or more. This delay is completely in line with studies by other researchers [39,40]: the reason can be ascribed to the number of complex molecules (diesel oil compounds) that are not easily and quickly degradable by indigenous microorganisms. Vice versa, with simple compounds, their fast removal is shown by the rate of respiration activity, to say the CO 2 production rate [35].…”

This study aimed to monitor the aerobic bioremediation of diesel oil-contaminated soil by measuring: a) the CO2 production; 2) the fluorescein production; 3) the residual diesel oil concentration. Moreover, the complex dielectric permittivity was monitored through an open-ended coaxial cable. Several microcosms were prepared, changing the water content (u% = 8–15% by weight), the carbon to nitrogen ratio (C/N = 20–450), and the soil amount (200 and 800 g of dry soil). The cumulative CO2 and fluorescein production showed similar trends, but different values since these two parameters reflect different features of the biological process occurring within each microcosm. The diesel oil removal efficiency depended on the microcosm characteristics. After 84 days, in the microcosms with 200 g of dry soil, the highest removal efficiency was achieved with a water content of 8% by weight and C/N = 120, while in the microcosms with 800 g of dry soil the best result was achieved with the water content equal to 12% by weight and C/N = 100. In the tested soil, the bioremediation process is efficient if the water content is in the range 8–12% by weight, and C/N is in the range 100–180; under these operative conditions, the diesel oil removal efficiency was about 65–70% after 84 days. The dielectric permittivity was monitored in microcosms with 200 g of dry soil. The open-ended coaxial cable detected significant variations of both the real and the imaginary component of the dielectric permittivity during the bioremediation process, due to the physical and chemical changes that occurred within the microcosms.

“…Decesaro et al. () used phycocyanin, which is a biomass of Spirulina platensis , as a biostimulant in bioremediation. They obtained the highest accumulated carbon values with the phycocyanin (2997.37 milligrams [mg] C─CO 2 ), followed by microalgae biomass (2882.90 mg C─CO 2 ).…”

“…The soil possesses an acidic pH, low organic matter content, high clay content, low cation exchange capacity, and generally has low permeability typical of soils with a predominance of kaolinite clay minerals (Thomé, Reginatto, Cecchin, & Colla, 2014). Physical and geotechnical characterization of the soil was performed and reported in previous studies (Decesaro et al, 2016).…”

“…According to Decesaro et al (2017), solutions of 13 mg.mL -1 of phycocyanin presented the surface tension of 37.21 mN.m −1 , compared with a tension of 58.29 mN.m -1 in the solution with 0.13 mg.mL −1 phycocyanin and 69 mN.m −1 in the sample of pure water, which demonstrates the dependency of the surfactant capacity of phycocyanin with concentration. So, we aimed to verify the dependence of surface tension of ice cream bases or ice cream formulations according to their composition.…”

Purpose The phycocyanin is a pigment present in the microalga Spirulina that has been studied due to its applicability as food coloring; however, it can be used due to the ability to act as an emulsifier or stabilizer in function of its protein characteristic. The purpose of this paper is to use aqueous extracts of Spirulina containing phycocyanin (EP) as a substitute of additives in the production of ice creams. Design/methodology/approach The study was divided in two sections: first, the influence of addition of EP in ice cream bases (that represent the ice cream preparation before air incorporation step) and second, the influence of addition of EP in five ice cream formulations, in which the differences were the addition of EP in substitution of stabilizer, Chantilly or emulsifier, one at a time or in substitution of all additives together, by the EP. Findings The different ice creams developed presented centesimal composition according to Brazilian legislation in relation to the chemical parameters. The EP presented emulsifying and stabilizing activity in the ice creams formulations acting in substitution of emulsifier and stabilizer presented in the standard formulation, not influencing the overall acceptability of consumers. Originality/value The authors demonstrate that the aqueous extract of Spirulina containing phycocyanin can be used as a natural additive in ice cream in substitution of emulsifiers and stabilizers normally used in this product, contributing to produce more healthy foods, once phycocyanin is an protein of high nutritional value.
