The work is devoted to the study of the physico-chemical and adsorption properties of synthetic and natural sorbents contaminated with oil products. The parameters such as sorption capacity for petroleum products, water adsorption and moisture content, bulk density, as well as parameters characterizing the sorption equilibrium in the surface layers (distribution coefficients, maximum adsorption values, Henry constants, Gibbs energy changes, adsorption coefficients and filling degrees) were determined. Adsorption isotherms for all sorbents are almost identical in character with a pronounced linear region in the region of low concentrations of oil products and correspond to isotherms of monomolecular adsorption. The sorption capacity of the sorbents under study varies from 10 to 50 mg of oil products per 1 g of sorbent. The maximum sorption capacity among the sorbents studied the Ol-Ex Hard possesses. This sorbent belongs to sorbents of the silicate group and Ol-Ex 82, based on polyurethane. The lowest moisture content is also characteristic for silicate sorbents and does not exceed 0.5 % of their mass. The maximum moisture adsorption is typical for sorbents of SONET Sorb and MGS Sorb. It was revealed that the surface of Ol-Ex Hard is almost completely filled with oil (q → 1), while for shungite the surface will be filled only by 13%. The most effective for trapping oil products should be considered the sorbent Ol-Ex Hard, for which the highest values of adsorption parameters are characteristic.Forcitation:Gusev G.I., Gushchin A.A., Filippov D.V., Grinevich V.I., Izvekova T.V.

Wood-inhabiting fungi are crucial to wood decay and decomposition in S. psammophila sand barriers, which in turn consumingly influence nutrient dynamics in desert soils. In the case of an extremely arid desert, as opposed to forests, little of known about the fungal community composition of decaying wood and the effects of decomposing wood on soil physical and chemical properties. Combined with high-throughput gene sequencing technology, we investigated the relationships between microenvironment factors with fungal community composition and diversity during the decomposition of Salix psammophila sand barriers. The results showed that the destruction of lignocellulose components during the decay process of S. psammophila sand barrier alters the physical and chemical properties of the surrounding soil. Compared with one-year sand barrier, lignin and cellulose of seven-year S. psammophila sand barrier decreased by 40.48% and 38.33%, respectively. Soil available potassium and available nitrogen increased by 39.80% and 99.46%, respectively. We confirmed that soil available nitrogen, soil pH and soil moisture content significantly affected the fungal community distribution of S. psammophila sand barriers. Sordariomycetes are mainly affected by the positive correlation of soil pH, while Eurotiomycetes are most affected by the positive correlation of soil moisture content and soil porosity. Although our results highlighted the importance of bidirectional interactions between fungi in decayed sand barriers and soil properties, their contribution to the desert ecosystem still needs further confirmation from future studies. However, overall our findings improved the current understanding of the sand barrier-soil interactions on the process of ecological restoration.

ObjectivesEnhancement of beef with non-meat ingredients is a common practice to improve both palatability and chemical characteristics. However, the delivery method of brine solutions has not been well studied and could play a role in the activity of certain ingredients, ultimately influencing meat characteristics. This study was designed to determine if different enhancement methods impacted the overall physical and chemical properties, including pH, percent pick-up, slice shear force (SSF), and cooked moisture content, of enhanced (water, salt and sodium tripolyphosphate) rectus abdominus.Materials and MethodsUSDA Select beef flank steaks (rectus abdominus) were procured from a beef abattoir and processed at 10 d postmortem. Steaks (n = 100; 20/treatment) were denuded and assigned randomly to one of the five treatments: untreated control (CNT), vacuum tumbled without marinade (TCNT), vacuum tumbled with marinade (TUMB), needle injected with marinade (INJ), and injected with marinade plus vacuum tumbled (IPT). Initial weight and pH were collected pre-enhancement for TUMB, INJ, and IPT. Samples were weighed again immediately after enhancement and 20 min after enhancement. Three weights were collected for IPT: pre-enhancement, post-injection and post-tumble. After flank enhancement, they were sliced in half parallel to the muscle fiber. One half was designated for laboratory analysis. The halves were then frozen and thawed 24 h prior to cooking. A 50-g raw sample was obtained from each flank prior to cooking for SSF to analyze raw moisture content. Each flank was cooked to an internal temperature of 72°C and allowed to rest for 3 min prior to slicing for SSF.ResultsTreatment influenced final pH (P < 0.01), with final pH increasing in INJ, TUMB, and IPT. Differences were noted in final pH between treatments; INJ had the highest pH (6.15), followed by IPT (6.06), TUMB (5.83), CNT (5.76), and TCNT (5.71), with a difference observed between each treatment (P < 0.05). Treatment also impacted (P < 0.01) SSF. The addition of marinade through injection and tumbling reduced (P < 0.05) SSF values, as CNT and TCNT had greater SSF values compared to all other treatments. Injection further reduced SSF values, as INJ and IPT had lower SSF values compared to TUMB (P < 0.05). Cooked moisture was also influenced (P < 0.01) by treatment. IPT and TUMB had greater moisture percentage compared to all other treatments; INJ was intermediate, and CNT and TCNT similarly had lower moisture percentage than the remaining treatments (P < 0.05). Of the three treatments that involved marination, initial and final percent pick-up and drip loss were all influenced by treatment (P < 0.01). Initially, INJ (14.5%) had the greatest percent pick-up, IPT was intermediate (12.9%), and TUMB had the lowest percentage (11.8%). However, drip loss was greatest for INJ (2.3%), intermediate for TUMB (0.2%), and lowest for IPT (0.0%). Final percent pick-up was now greatest for IPT (12.9%), intermediate for INJ (11.9%), and lowest for TUMB (11.5%).ConclusionEnhancement methods can influence physical and chemical traits in terms of moisture, SSF and pH. Injection influenced shear force more than tumbling, whereas tumbling had greater effects on moisture than injection. Combining injection with tumbling had the most positive effect on shear force as well as moisture retention.

1. Six cheese of Cheddar type were made under conditions as similar as possible, except that the consistency of the curd at pitching, and in two cases the rate of scald, were varied.2. Chemical and rheological analyses, as well as measurements of moisture content and vapour pressure, were made on the cheese and also judgements of firmness under various conditions were given by cheese-makers, bakers and non-experts.3. A table is given in which the orders of placing of the cheese are compared as between the objective tests and the subjective judgements. The cheese-makers and the non-expert testers gave, in general, characteristically different orders, the orders given by the bakers tending to fall between the two.4. It appears that the consistency of the curd at the pitching point (W/h as determined by the Scott Blair-Coppen method) and probably the rate of scald, are prime factors in determining the firmness of the cheese.5. The whole experiment is preliminary in character and it is intended to repeat it in an extended form in the near future.
