В последние годы активно расширяется рынок микробиологических удобрений. Для того, чтобы новые биоудобрения эффективно работали, важно не только подбирать качественный и количественный состав микроорганизмов, но и изучать влияние этих бактерий на их численность, распространение и долговременность пребывания в почве, а также воздействие на растения. Цель исследования: выявить влияние способа получения удобрения на основе молочной сыворотки, содержащей Streptomyces coelicolor, на количество и длительность содержания этих бактерий в почве, а также на ростовые характеристики горчицы белой (Sinapis alba L.), посеянной в почву через длительный временной интервал после полива удобрением.</p></sec><sec><title>Методы</title><p>Методы. Биоудобрение получали, выращивая бактерии Streptomyces coelicolor на разведенной и автоклавированной молочной сыворотке. Инокулят для удобрения получали двумя способами: однократным культивированием на жидкой среде Ваксмана и последовательным культивированием в молочной сыворотке в возрастающих объемах. Культивировали без перемешивания и с перемешиванием в термостатируемом шейкере. Эффективность удобрений изучали в лабораторных условиях на почвах в контейнерах. Количество Streptomyces coelicolor в почве определяли через 0,5, 1,5, 2 и 4 месяца после полива удобрениями. Влияние удобрения на семена горчицы белой, посеянной через два месяца после полива, определяли по характеристикам качества семян, количеству листьев и ростовым параметрам листовых пластинок.</p></sec><sec><title>Результаты</title><p>Результаты. Удобрение, полученное путем последовательного культивирования инокулята и выращиванием стрептомицетов без перемешивания, содержало в десять раз больше стрептомицетов, чем удобрения, полученные другим способом, а также эффективнее увеличивало количество стрептомицетов в почве. После однократного применения удобрений стрептомицеты длительно сохранялись в почве. По влиянию на количество листьев и площадь листовой пластинки самыми эффективными оказались удобрения, культивируемые без перемешивания.</p></sec><sec><title>Заключение</title><p>Заключение. Удобрение, полученное методом последовательного культивирования инокулята в возрастающих объемах и выращивания стрептомицетов без перемешивания, способствует большему увеличению стрептомицетов в почве и более эффективно при выращивании горчицы белой, по сравнению с удобрениями, полученными другими способами. Оно эффективно действует на рост культур, посеянных в почву через длительное время после полива. Удобрение можно применять в комнатном растениеводстве и тепличных хозяйствах.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance. In recent years, we have seen an increase in the number of new bacterial fertilizers. New fertilizers must be effective, so it is important to select their qualitative and quantitative composition. It is equally important to study the effect of these bacteria on their number, dissemination and long-term residence in the soil, as well as their effects on plants.</p></sec><sec><title>Aim of the Study</title><p>Aim of the Study. This work studies the effect of the method of obtaining a fertilizer containing Streptomyces coelicolor grown on the whey on the amount and duration of these bacteria in the soil and on the growth characteristics of white mustard (Sinapis alba L.) sown into the soil after a long time after watering with fertilizer.</p></sec><sec><title>Methods</title><p>Methods. The whey was diluted and autoclaved, Streptomyces coelicolor were grown on this substrate. An inoculum for this biofertilizer was obtained in two ways. The first way: Streptomyces coelicolor were grown once on a Waksman`s media. The second way: the inoculum was sequentially grown on the whey, gradually increasing the volume. Bacteria in fertilizer were cultivated without mixing or by mixing in the temperature-controlled shaker. We studied the effect of biofertilizer on soil in containers in the laboratory. The amount of Streptomyces coelicolor in the soil was determined 0.5, 1.5, 2 and 4 months after watering by fertilizer. Seeds of white mustard were sown two months after watering with fertilizer. We studied the effect of fertilizer on growth characteristics of white mustard.</p></sec><sec><title>Results</title><p>Results. The fertilizer obtained by sequentially cultivating the inoculum and growing streptomyces without mixing contained ten times more streptomyces than fertilizers obtained by another method. This biofertilizer also effectively increased the number of streptomyces in the soil. Streptomyces from fertilizer have been preserved in the soil for a long time. The effect of biofertilizers obtaining without mixing on growth characteristics of white mustard was the most effectively.</p></sec><sec><title>Conclusion</title><p>Conclusion. The fertilizer obtained by sequentially cultivating the inoculum and growing streptomyces without mixing contributes to a more increase of streptomyces number in the soil and is more effective in growing white mustard then fertilizers obtained by other methods. Our biofertilizer is effective in growing crops sown in the soil for a long time after watering with fertilizer. The fertilizer can be used in indoor crop production and greenhouse farms.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>биоудобрение</kwd><kwd>молочная сыворотка</kwd><kwd>Streptomyces coelicolor</kwd></kwd-group><kwd-group xml:lang="en"><kwd>biofertilizer</kwd><kwd>dairy whey</kwd><kwd>Streptomyces coelicolor</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Shahwar D., Mushtaq Z., Mushtaq H., Alqarawi A.A., Younghoon Park Y., Alshahran T.S., Faizan S.
