Aim. The purpose of the study was to investigate the effect of ultrasonic disintegration on the lignocellulosic raw materials (biomass of the non-cereal part of rape) with its subsequent use as a substrate for the production of biobutanol. Methods. Butanol-producing strains and the biomass of the non-cereal part of rape Brassica napus were used in the present study. Ultrasonic disintegration of lignocellulosic raw materials was performed on the specially designed equipment. Results. The effect of ultrasonic disintegration on lignocellulosic raw materials was investigated for further application in biofuel production based on microbiological conversion. The possibility of using the obtained components after the pre-treatment of lignocellulose by ultrasonic disintegration as a substrate for the microbiological synthesis of butanol was shown. The highest accumulation of butanol (2.4 g/l) was obtained with the use of 5% dry matter content in the medium, 5 min treatment and the specific power of ultrasonic disintegration of 0.72 W/ml. Conclusions. The possibility of producer strains of the genus Clostridium to use cellulose in the fermentation process has been shown. When using ultrasonic disintegration for pretreatment of the non-cereal part of the biomass of rape, the accumulation of butanol increased by 3 folds.

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%.

The article presents the investigation of the chemical composition of a collagen-containing broth obtained during gelatin production at the stage of defatting bony raw material. Collagen broth is a minor by-product from gelatin production. The aim of the research is to analyze the effect of the duration of the hydrothermal treatment of collagen raw materials on the concentration of high-protein broths by using spray drying. To carry out a set of experimental studies they used broth obtained by the method of hydrothermal treatment of bone at a temperature of 95±5°C for 90 to 180 minutes and its dry concentrate obtained later at the Mini Spray Dryer B-290 laboratory spray drying model (Buchi, Sweden). According to the research results, it has been revealed that the duration of the hydrothermal treatment affects the indicators of fat, protein, and dry matter content in broths. When being treated for 90 minutes, the dry matter content is in the range of 8,1 %, which is 46 % less than with a treatment time of 180 minutes. When the duration of the hydrothermal treatment of raw materials increases, the gelation time of the obtained broths reduces at temperature conditions of 4±2°C. After the spray drying process physicochemical parameters of the obtained dry collagen concentrates have been determined. In the dry concentrate the dependence of the indicator of the content of the mass fraction of protein on the duration of the hydrothermal treatment of broths is observed, the values range from 64,19 % to 82,89 %. The gelling capacity of all samples is high. The obtained dry concentrates are in the form of white to light cream color homogeneous powder.

Background. The disadvantage of the two-product technology of alcohol and baker’s yeast from molasses is the need to limit the concentration of dry matter of the source medium to 22% and, accordingly, the level of alcohol accumulation in mature malt not more than 8.0% vol. to prevent deterioration of baker’s yeast. The consequence of this is the high specific cost of steam for bragorectification and increase the specific yield of post-alcohol molasses bard in comparison with single-product technology (obtaining only alcohol). Materials and methods. Raw materials, intermediates and final products were analyzed according to the methods adopted in science and practice of molasses alcohol technology. The dry matter content; pH of the medium; the content of alcohol in the brew, yeast biomass and unfermented sugars; the lifting power of yeast and their color in the resulting products were determined. Results. The possibility of reducing the volume of post-alcoholic molasses bard by returning it for the preparation of molasses bard without deteriorating the quality of baker’s yeast and alcohol yield, as well as by increasing the dry matter concentration of fermented wort from 22 (traditional technology) to 27% and accumulation of alcohol in mature brew up to 10–11% vol. has been experimentally proven. Conclusion. The presented research results provide grounds for the development of energy-saving low-waste two-stage technology of alcohol and baking yeast from mo­lasses, which can be used to obtain high-quality baking yeast to increase the con­centration of alcohol in mature malt by more than 10% vol. This will significantly reduce the steam for bragorectification of alcohol and the volume of contaminated and difficult to dispose of production waste – post-alcohol molasses bard. The implementation of such technology will be the next step in the greening of the joint production of alcohol and baker’s yeast from molasses.

Vegetative Organs

The dry matter and moisture contents of the aboveground vegetative organs and kernels of four maize hybrids were studied in Martonvásár at five harvest dates, with four replications per hybrid. The dry matter yield per hectare of the kernels and other plant organs were investigated in order to obtain data on the optimum date of harvest for the purposes of biogas and silage production.It was found that the dry mass of the aboveground vegetative organs, both individually and in total, did not increase after silking. During the last third of the ripening period, however, a significant reduction in the dry matter content was sometimes observed as a function of the length of the vegetation period. The data suggest that, with the exception of extreme weather conditions or an extremely long vegetation period, the maximum dry matter yield could be expected to range from 22–42%, depending on the vegetation period of the variety. The harvest date should be chosen to give a kernel moisture content of above 35% for biogas production and below 35% for silage production. In this phenophase most varieties mature when the stalks are still green, so it is unlikely that transport costs can be reduced by waiting for the vegetative mass to dry.
