Abstract Energy variety of amaranth (Amaranthus spp.) was grown in large-scale trials in order to verify the capability of its cultivation and use as a renewable energy source in a biogas plant. The possibility of biogas production using anaerobic co-fermentation of manure and amaranth silage was verified in the experimental horizontal fermentor of 5 m3 volume, working at mesophilic conditions of 38-40 °C. The goal of the work was also to identify the optimum conditions for growth, harvesting and preservation of amaranth biomass, to optimize biogas production process, and to test the residual slurry from digestion process as a high quality organic fertilizer. The average yield of green amaranth biomass was 51.66 t.ha-1 with dry matter content of 37%. Based on the reached results it can be concluded that amaranth silage, solely or together with another organic materials of agricultural origin, is a suitable raw material for biogas production.

Abstract The rising population and increasing demand for food place added pressure on the agricultural sector to maintain high process efficiency while implementing environmentally friendly methods. In this study, we investigate the effect of pre-hydrolysis of native rye starch and its influence on the yield of ethanol obtained by simultaneous saccharification and fermentation (SSF) from high gravity rye mashes with 25% and 28% w w−1 dry matter content. Fermentation was carried out in a 3-day system at a temperature of 35 ± 1 °C using the dry distillery yeast Ethanol Red (Saccharomyces cerevisiae). The characteristics of the tested raw material and changes in the native rye starch during enzymatic hydrolysis were analyzed using a scanning electron microscope (SEM). The SEM images revealed characteristic changes on the surface of the starch, which was found to have a layered structure, as well as interesting behavior by the yeast during SSF when the glucose concentration in the environment was lowered. Both in the mashes with 25% and 28% w w−1 dry matter, starch pre-hydrolysis did not significantly increase either the initial amounts of sugars available to the yeast or the fermentation efficiency and ethanol yield in comparison to the mashes without this pre-treatment.

The Relationship

The correlation between dry matter (DM) content, electrical conductivity (EC) and ash content was found to be linear in grass and alfalfa during drying. While minerals in grass and alfalfa were very stable components during drying, their concentrations and EC increase accordingly; therefore, the EC value could serve as a measurement to determine DM content. Results indicated that EC measurement in grass and alfalfa during drying was simple, accurate, fast and easily repeatable, and could serve as an alternative method for DM determination.

The Impact

This paper deals with the Reynoutria × bohemica and Reynoutria japonica under conditions of the Czech Republic. It evaluates the impact of soil, weather conditions and various terms of harvest (autumn, spring) on the yield, dry matter content, phytomass loss, ash content, and basic elements content change in plants. Heavy metals content was determined in soil where plants were grown and consequently in plants themselves. The average yield of dry matter at the fully closed stands of Reynoutria japonica were 9.06 t/ha in autumn, Reynoutria × bohemica from 13.23 to 21.41 t/ha, according to the site. The yield losses within the winter period were found on average 42% for Reynoutria japonica and 34% for Reynoutria × bohemica. The moisture decrease of Reynoutria japonica was found from 68% in the autumn to 24% in the spring, and of Reynoutria × bohemica from 67% to 23%, respectively. Decreased content of nitrogen, phosphorus, potassium, calcium, and magnesium in the knotweed phytomass was found during the latter (spring) harvest periods in comparison with the earlier harvest periods. Decreased elements content in phytomass during the latter harvest period (spring) increases the phytomass quality as a fuel from both aspects – technical and emissions generation. The ash content in plants varied according to the site, on average from 3.12% in Ruzyně to 4.6% in Chomutov. None of the heavy metals monitored in knotweed plants reached the maximum admissible values determined for the food or feed purposes in the Czech Republic. From the results of combustion experiments, it is evident that Reynoutria × bohemica is a good fuel. Energy sorrel shows the extreme CO concentration in flue gases in comparison with other monitored fuels. According to the ČSN EN 12809 (2001) standard it does not meet even the third class of requirements. On the contrary, knotweed and wood bark fulfill the requirements for the first class. The surprising fact is that both of these fuels show the lower level of CO emissions, than the wooden briquettes. Concentrations of nitrogen oxids are comparable with biofuels, except of wood, and probably are related to the nitrogen content in heating material.

Background. Representatives of the genus Allium L. are valuable food and medicinal plants that have long been used for nutrition and human health. Modern research has proved their high biological activity. Earlier, we investigated the aboveground organs of a number of wild onion species in the consumer ripeness phase. Higher content of secondary metabolites has been observed in the hemiephemeroid species A. aflatunense B. Fedtsch., A. microdictyon Prokh., and A. rosenbachianum Regel. The aim of this work was to determine the content of bioactive compounds in the green biomass of Allium species during flowering.Materials and methods. We studied the freshly harvested raw materials – leaves and flower scapes. Dry matter content was measured by drying 1 g of raw material at 100–105°C to constant weight. The amounts of phenolic compounds, pectic substances, total sugars and carotenoids were assessed spectrophotometrically using the SF-56 (Russia) and SF Agilent 8453 (USA) instruments, and ascorbic acid was measured by the titrimetric method. The result was taken as an average of three measurements for each indicator calculated on absolute dry weight of raw material (except ascorbic acid).Results and conclusions. The green biomass of Allium species was found to contain 8,2–16,2% of dry matter; 4,5–12,0% of phenolics (catechins, flavonols and tannins); 6,9–32,4% of total sugars; 9,5–12,6% of pectic compounds (pectins and protopectins); 20,8–102,5 mg% of carotenoids, and 38,0–197,7 mg% of ascorbic acid (wet weight). A significant range of variation in the content of secondary metabolites was due to the species’ characteristics and weather conditions of the growing season. A. microdictyon had a higher content of dry matter, flavonols and tannins, whereas A. aflatunense and A. rosenbachianum were rich in ascorbic acid and sugars. The findings testify to the prospects of using Allium spp. as a source of bioactive compounds.

Whey proteins, which are mainly composed of β-lactoglobulin (β-lg) and α-lactalbumin (α-la), account for about 20% of the proteins of bovine milk. In this study we investigated the effect of pH, dry matter content, concentration factor, heat treatment and centrifugation on the separation of α-la from β-lg using clarified whey as raw material, α-La precipitation was highest, 23.3%, when the dry matter content ranged from 5.8% to 25.7%. The optimum pH of α-la precipitation depended on the dry matter content. The separation efficiency increased when the concentration factor and heat treatment time at 55°C increased. A longer centrifugation time and higher separation speed did not have a marked effect on the separation efficiency. Separation was more efficient with a higher centrifugation speed at concentration levels 30 X and 60 X. The separation efficiency did not improve when the temperature was raised from 55°C to 65°C but it was better at a concentration level 120 X than at 60 X and 30 X, and also at concentration level 60 X than with 30 X.

The urgency of the use of blood components as a raw material for the production of products from it that contribute to the prevention and treatment of iron deficiency states is beyond doubt. In addition, protein compounds in the blood of cattle have a high digestibility of the human body, and the complex of essential amino acids determines its attractiveness as an additive in the development of a wide range of meat products. The only possible way at present to thicken thermo labile blood compounds is cryoconcentration, carried out in a temperature range close to the cryoscopy temperature. The kinetic features of cryoconcentration of cattle blood were investigated on an experimental apparatus of cyclic action. It is shown that the conditions of cryoconcentration are determined by the boiling point of the refrigerant in the evaporator of the installation, the flow rate of the original blood washing the heat exchange surface and the content of soluble compounds in the initial liquid. Experimental data are presented in the form of growth curves of frozen ice on the heat exchange surface with an area of 0.2 m2. Using mathematical planning methods, equations are obtained that describe the amount of ice frozen for 1 hour per unit of surface area of the freezing plant, the specific energy input for freezing one kilogram of ice, and the dry matter content of the blood in the solution obtained by melting the frozen ice. The solved problem of optimizing the process of blood cryoconcentration made it possible to find rational intervals for changing the operating parameters of the freezing plant, ensuring the maximum amount of frozen ice, minimal energy costs and minimal content of soluble substances in the solution obtained by melting frozen ice. The suboptimal intervals of the indicated parameters were the following: refrigerant boiling point 256– 260 K, blood consumption (0.20–0.205)·10-3 m3/s, dry matter content 22.5–23.0 %.

For the production of high quality silage, and reduction of losses of biological yield, the use of effective biological preparations is topical. In order to reveal the effectiveness of the preservation of nutrients from plant raw materials, a number of laboratory studies were carried out in 2016-2017 in the Tatar Scientific Research Institute of Agriculture (TatNIISKh). The object of research was haylage harvested from the green mass of alfalfa, grown on the experimental field “TatNIISh” in Laishevsky district of the Republic of Tatarstan. The nutritional value of the conserved green mass of the alfalfa (Medicago sativa) variety Aisleau in the phase of budding with different moisture was analyzed. Preservation of the planted plant mass was carried out using biological preparations Biotrof (St. Petersburg), Ferbak-Sil (Kazan), Bioamid-3 (Saratov). The variant with biological preparation Biotroph served as the control. The maximum content of exchange energy (EE), with an increased concentration of phytomass moisture, was established in the control sample, which was 2.36 MJ/kg and was higher than the experimental samples with Bioamid-3 and Ferbak-Sil preparations at 6.78 and 3.82 %. With an increased dry matter content in the green mass of alfalfa, this indicator was the maximum in the sample with the preparation Bioamid-3 (3.67 MJ/kg), which was higher than the control by 4.56%. The leader in the concentration of crude protein and crude fiber, with a high moisture content of raw materials, was set in a control sample and amounted to 6.11 and 6.07%, which were higher than the prototypes with Bioamid-3 and Ferbak-Sil preservatives by 0.33 and 0.16%, 0.76 and 0.48% respectively. The leading preservative for the preservation of raw protein and crude fiber, with reduced moisture content of raw materials, showed the drug Bioamid-3, whose indices were above the control by 0.39 and 0.23%.

Seeds are usually infected by microorganisms and pests during storage, causing deterioration and reduction in the nutritive and market value of these seeds. In this study, the proximate composition of Vigna unguiculata seeds inoculated with different fungal organisms was determined to ascertain the level of deterioration caused by fungi on the seeds. The fungi used in the study were Botryodiplodia theobromae, Fusarium oxysporum, Rhizopus stolonifer and Aspergillus niger. There was a significant increase (p<0.05, 0.008) in the protein content of seeds inoculated with fungi. Fusarium oxysporum (29.45%) caused the highest increase in protein followed by Aspergillus niger (28.14%), Botryodiplodia theobromae (27.85%) and Rhizopus stolonifer (27.50%). The increase could be attributed to the proteineous content of the fungal mycelia. There was a significant increase (p<0.05, 0.005/0.014) in moisture and ash content of inoculated seeds respectively. Fusarium oxysporum caused the highest increase in ash (7.93) while Rhizopus stolonifer (5.4) caused the lowest increase. The increase in ash content is due to the presence of minerals like potassium and phosphorus in the mycelia of the fungi. There was a significant decrease (p<0.05, 0.019) in the carbohydrate, lipid, fibre and dry matter content of fungi-inoculated seeds when compared with the control. Fusarium oxysporum (36.6) caused the highest decrease while Rhizopus stolonifer (43.2) caused the lowest decrease in dry matter of inoculated seeds. Decrease in dry matter may be as a result of production of enzymes by these fungi.

The research was undertaken to determine the amounts of precipitate formed in the milk plasma due to mixing of different levels of heated milk with raw milk, and to establish a turbidity index, which will be helpful as a field method in detecting the extent of addition of heated milk. The tests were conducted on five different treatments namely, Milk sample A (100% Heated milk), Milk sample B (75% Heated milk + 25% Raw milk), Milk sample C (50% Heated milk + 50% Raw milk), Milk sample D (25% Heated milk + 75% Raw milk) and Milk sample E (100% Raw milk). Samples were examined by chemical analysis including fat content, protein content, dry matter content, ash content, pH, acidity, turbidity test, and precipitation content of plasma. There was a highly significant difference (p<0.001) in case of fat, protein and precipitate contents of plasma as affected by extent of addition of heated milk. A statistically significant difference (p<0.05) was also found for ash content. On the other hand, no significant difference was found in case of dry matter content, pH and acidity of milk. A strong correlation (R2=0.819) was observed between the amount of precipitate and proportion of heated milk mixed with raw milk. A field method was devised on the basis of extent of turbidity, which was in fact amount of precipitate formed in the milk plasma as a function of extent of the addition of heated milk to raw milk.DOI: http://dx.doi.org/10.3329/bjas.v43i2.20708 Bang.
