Regeneration Potential of Alginite for the Depletion of Organic Contaminants from Wastewater

The publication aims to present some knowledge about the less-known but at the same time very scarce bituminous rock alginite with comprehensive practical use in the form of a brief overview. Alginite is an organic-bituminous rock that was formed about six million years ago from dead fossil algae Botryococcus braunii Kütz and diatoms in the area of today's Pannonian Basin. In Europe, alginite deposits have been discovered in Hungary, Austria and Slovakia in Pinciná village. Alginite mining is mostly used in Hungary in the Gerce area. Alginite is grey to dark grey, in the wet state dark laminated, clayey with the form of disintegrating clay. Alginite has very valuable physical, mechanical and chemical properties. It is a natural bituminous rock with a favourable content of basic nutrients (P, K, Ca, Mg and S) for plants except for nitrogen content. Alginite contains a large number of microelements, which increase the agrochemical possibilities of its use. It can be applied in its natural form without chemical treatment. It is an ecological raw material that improves the soil and does not negatively affec the environment. Alginite has become the subject of research in many workplaces. The overview presents the basic physical, mechanical and chemical properties of alginite and selected knowledge and research results that have enabled the practical use of alginite in natural or technologically modified form in agriculture in the formation of growth, development and crop formation and quality of seeds and fruits of cultivated crops, forestry, remediation and improvement of soil and water properties, decomposition of herbicides, stabilization of beneficial microorganisms in animal organisms and other areas.

“…Alginite was found in Slovakia in Maar near Pinciná village northeast of the town of Lučenec (Vass et al, 1997). A study of alginite and its effect on plant growth was conducted by several research groups (Barančíková et al, 2003;Gömöryová et al, 2009;Brindza et al, 2021a;2021b;Kropp et al, 2021).…”

Stimulation Effect of Alginite on Rhodiola rosea L. in vitro Growth

Stimulating the growth of plants, increasing their productivity, and resistance to stress factors are important tasks facing scientists and producers of agricultural products. Different compounds of natural origin can be used as biostimulants. Such chemicals as humic, fulvic, and salicylic acids, mineral elements, amino acids, chitosan, vitamins, poly-, and oligosaccharides are the typical components of biostimulants. They affected not only plant growth. Biostimulants also improve biosynthetic activity, including chlorophyll synthesis, and accumulation of plant metabolites. Alginite, founded in Slovakia in Maar near Pinciná village northeast of Lučenec, was studied as a plant growth stimulator. The application of biostimulants to medicinal plants allows increasing in their biomass and productivity. The effect of alginite on in vitro growth of Rhodiola rosea L. plants and their antioxidant activity has been analyzed in this study. Adding 1 or 10 mL.L -1 of MS medium alginite extract solution diluted to the concentration of 1% resulted in intensive plant growth. Shoots weight increased 4.48-6.64-fold compared to the control. Adding alginite extract solution also stimulated root growth (3.00-5.58-fold). Despite the decrease in the specific content of flavonoids in the plants, grown on media with alginite, the total content of flavonoids in these plants was higher than in the control ones due to a significant increase in biomass. The antioxidant activity of the samples grown on the alginite medium was higher than that of the control plants. Thus, alginite, a compound of natural origin, can stimulate the growth of R. rosea and increase the bioactivity of these plants.

“…The alginite has high water absorption capacity -up to 110 % and high specific surface (313-654 m 2 special features of the organic matter (kerogen type II) and by the presence of smectite (Brindza et al, 2021a). According to many authors, alginite, due to its exceptional chemical composition, improves the soil properties, thereby affecting the growth and development of plants, contributes to increase yields (Rauch and Földényi, 2012;Kádár et al, 2015;Benei and Rauch, 2016;Bednárová, 2019;Kropp et al, 2021).…”

Biological Effects of Alginite on Tomato Plants (Lycopersicon esculentum) and Some Insects (Leptinotarsa decemlineata, Galleria mellonella and Halyomorpha halys)

2021

The purpose of our work was to study the effect of Slovak origin alginite on germination of tomato seeds, growth and development of plants, as well as to evaluate biological activity of alginite against to insect pests. Tomato seeds with low germination capacity were treated by immersion in alginite solutions of concentration 0.0001-0.1 %. Alginite solutions with concentrations of 0.1-5.0 % were used for testing against insects. The application of alginite solutions significantly increases the germination of tomato seeds in laboratory conditions by 9.2-13.0 %. There was a significant increase in the length of seedlings and roots by 1.87-2.98 cm and 3.54-4.51 cm. In a greenhouse presowing treatment of tomato seeds with 0.001 % alginite solution significantly increased germination in comparison with the control (by 33.2 %) and 0.01 and 0.1 % alginite solutions (by 22.2 and 25.0 %). Monitoring of plant height showed that a month after the first seedlings emergence the average plant height was significantly higher in the variant 0.001 % alginite solution and reached to 11.41 cm. The yield of fruits in the variants treated with alginite solutions significantly exceeded the control by 316.53-327.71 g per one tomato bush. It was found that alginite solutions at a concentration of 0.1-1.0 % had low ovicidal (2.73-13.19 %) and insecticidal (5.0-33.3 %) effects against insects belonging to different orders -Leptinotarsa decemlineata (Coleoptera), Galleria mellonella (Lepidoptera) and Halyomorpha halys (Hemiptera). Alginite solutions did not have contact insecticidal activity; the death of insects was caused mainly by the consumption of treated feed. At the same time, a high antifeedant effect was revealed from 45.0 to 85.0 % against adults and larvae of 2-3 instars of L. decemlineata and larvae of 2-3 instars of G. mellonella. To conclude, the application of alginite contributed to an increase in seed germination and plant productivity, and it did not reveal significant biological activity against insects.
