Compost has a broad application in terms of the improvement of the soil properties. This research work was conducted to present the molecular implications of using compost obtained from different substrates to improve soil parameters for cucumber seedlings cultivation. In the experiment, the following compost mixtures were used: sewage sludge (80%) + sawdust (20%); sewage sludge (40%) + sawdust (10%) + biodegradable garden and park waste (50%); biodegradable garden and park waste (90%) + sawdust (10%); sewage sludge (80%) + sawdust (20%) + ; sewage sludge (40%) + sawdust (10%) + biodegradable garden and park waste (50%) + ; biodegradable garden and park waste (90%) + sawdust (10%) + .

Variability of Properties Modulating the Biosynthesis of Biologically Active Compounds in Young Barley Treated with Ozonated Water.

This paper presents the effects of irrigating barley plants with different type of water solutions saturated with gaseous ozone generated from atmospheric air. The study investigated the effects of the applied types of water on the modulation of the biosynthesis of selected bioactive compounds (content of total polyphenols, small molecule antioxidants, vitamin C) in the produced plant material. A number of transformations of reactive oxygen species (ROS) and nitrogen compounds have also been postulated; these are observed during the saturation of water with gaseous O and 30 min after the end of the process.

The Modification of Substrate in the Soilless Cultivation of Raspberries ( L.) as a Factor Stimulating the Biosynthesis of Selected Bioactive Compounds in Fruits.

Raspberry fruits are a valuable source of bioactive compounds. The study used the modification of the substrate (coconut fibre), consisting of the use of various organic and mineral additives, in the soilless cultivation of raspberries. The additives influenced the biosynthesis of bioactive compounds in the raspberry fruits by modifying the sorption properties and the abundance of the substrate.

Induction of Biosynthesis Antioxidant Molecules in Young Barley Plants by Trioxygen.

Young barley plants are a good source of bioactive compounds. This paper presents the effects of gaseous O (trioxygen or ozone) on the biosynthesis of compounds, determining the antioxidant potential of young barley plants. The total content of polyphenols was determined along with their profile, as well as total antioxidant potential and vitamin C content.

Fruits of Nutt. ex M. Roem.

Characterisation of Some Phytochemicals Extracted from Black Elder ( L.) Flowers Subjected to Ozone Treatment.

Elderflowers are a well-known source of bioactive compounds. The amount of isolated bioactive compounds may be increased by applying various abiotic and biotic factors. Gaseous ozone (10 and 100 ppm) was used in the process of preparing flowers.

Effect of Ozone Treatment on the Quality of Sea Buckthorn ( L.).

The aim of this research was to show the effect of the ozonation process on the quality of sea buckthorn ( L.). The quality of the ozonated berries of sea buckthorn was assessed.

Effects of Ozone Treatment on Microbial Status and the Contents of Selected Bioactive Compounds in L. Plants.

This study presents the effects of ozone treatment on microbial status and contents of selected bioactive compounds in marjoram plants. L. is a widely used plant which in the course of production is affected by microbial infections.

Influence of Drying Method on Some Bioactive Compounds and the Composition of Volatile Components in Dried Pink Rock Rose ( L.).

This study investigates the effects of various drying methods applied to leaves of L. on the contents of polyphenols and the composition of the volatile fraction. The following four drying methods were used: convection drying at a temperature of 40 °C (CD 40 °C), 50 °C (CD 50 °C), and 60 °C (CD 60 °C); vacuum-microwave (VMD 240 W); combined drying, involving convection pre-drying (50 °C) and vacuum-microwave (240 W) finish drying (CPD-VMFD) as well as freeze-drying (FD).

Mechanism of nutrition activity of a microgranule fertilizer fortified with proteins.

Background: A microgranule fertilizer was designed for localized fertilization of soil with controlled release of nutrients. The microgranule matrix was fortified with proteins, which were obtained from food industry byproducts or waste, i.e.

The effect of drying methods on the energy consumption, bioactive potential and colour of dried leaves of Pink Rock Rose ().

This study aimed to investigate the changes in the total polyphenolic content and antioxidant properties after subjecting Pink Rock Rose () leaves to three different drying procedures, including convection drying (CD) at 40, 50 and 60 °C; vacuum-microwave drying (VMD) at 240 W microwave power; and combined drying consisting of convective pre-drying at 50 °C followed by vacuum-microwave finish drying at 240 W microwave power (CPD-VMFD). The total polyphenolic content and antioxidant properties (DPPH, ABTS) of leaves subjected to these three drying methods were spectrophotometrically determined. The results show that convection drying at 40 °C and vacuum-microwave drying yielded dried leaves with the highest bioactive potential in terms of the total polyphenol content and antioxidant activity, with the highest and lowest values of final specific energy consumption, respectively.

Phytochemical Compounds and Antioxidant Activity in Different Cultivars of Cranberry (Vaccinium Macrocarpon L).

Unlabelled: Cranberries can be a component of a healthy diet, because they are a great source of health-promoting compounds and nutrients. The aims of this study were to evaluated phytochemicals and antioxidant activity in 6 cultivars of cranberry fruit grown in Poland. The content of polyphenols, carotenoids, chlorophylls, and triterpenoids were determined with the use of UPLC-PDA-MS/MS, although antioxidant activity was examined with DPPH, ABTS, and FRAP assays.
