Optimization of the microbiological composition of the biological product for cultivation of Lotus corniculatus

L.I. Domracheva, D.V. Kozylbayeva, A.L. Kovina, L.V. Trefilova, Yu.N. Zykova, M.N. Gripas & V.A. Izotova
In a field experiment the effectiveness of presowing treatment of seeds of Lotus corniculatus by mono- and multicomponent microbial associations has been investigated. The associations were based on the nodule bacteria (NB) of Rhizobium loti, cyanobacteria (CB) Fischerella muscicola and actinobacteria (AB) Streptomyces hygroscopicus A4. Evaluation of effectiveness was carried out by the analysis of morphometric parameters of the aerial part and the plants biomass, as well as the intensity of the tubercles formation. The...

Alternative energy: methanol, ethanol and alcohol esters of rapeseed oil as eco-friendly biofuel

А. Marchuk, V. A. Likhanov & O. P. Lopatin
The authors of the article explain the necessity of using eco-friendly biofuel for motor vehicles. The possibilities and ways of using biofuel in motor vehicles on the basis of alcohols (methanol, ethanol) and methyl ester of rapeseed oil are analyzed. The physical and chemical properties of these biofuel types are presented. In order to develop, determine and optimize the composition of eco-friendly biofuel for motor diesel engines, the authors have tested them during their work...

Biosorption of heavy metals by micromycetes: specificity of the process, mechanisms, kinetics

S.G. Skugoreva, G.Ya. Kantor & L.I. Domracheva
One of the ways to remove heavy metal (HM) compounds from the environment is biosorption. Most studies on biosorption are carried out on microorganisms, among which micromycetes occupy leading positions. They have a high degree of adaptation and resistance to the action of HM, are able to accumulate and transform HM compounds, show high sorption activity in relation to them. A feature of the cell wall of micromycetes is the predominance of polysaccharides (in particular,...

Отклик почвенной цианобактерии Nostoc paludosum на действие cульфата меди(II) в присутствии глутатиона восстановленного

А.И. Фокина, Е.И. Лялина, Л.В. Трефилова & Т.Я. Ашихмина
Изучено влияние растворов CuSO4 с концентрациями ионов Cu2+, равными 1, 2, 3, 4 и 5 мг/дм3 , с добавлением трипептида – глутатиона восстановленного (GSH) и без него на почвенную цианобактерию (ЦБ) Nostoc paludosum 18. Продолжительность экспозиции культуры с растворами составила 72 часа. В ходе эксперимента наблюдали за формированием биоплёнок ЦБ из гомогената, как за показателем восстановления исходной популяции; измеряли концентрацию растворённого O2 в суспензиях ЦБ; определяли долю клеток ЦБ, способных к образованию формазана из 2,3,5-трифенилтетразолий...

Problems of state regulation of the organization of protection zones for hunting resources

I.A. Grebnev
The subject of the research is the legislation regulating the organization of zones of protection of hunting resources. On the basis of theoretical assumptions, analysis of normative-legal acts, the author identifies areas and proposes concrete measures to improve legislation and law enforcement practice in the field of territorial protection of hunting resources (wild animals being objects of hunting). Work was carried out on the basis of a systematic approach using formal-logical and comparative legal research...

Reducing the emission of odorous substances in industrial pig breeding enterprises

Yu.N. Terentyev, N.V. Syrchina, T.Ya. Ashikhmina & L.V. Pilip
Pig-breeding enterprises are a source of intense odor pollution of atmospheric air. The enlargement of the existing complexes and construction of new ones leads to a significant exacerbation of the problem of odor pollution and numerous public complaints about the state of the environment. The current situation determines the high relevance and practical significance of research aimed at solving the problem of reducing the emission of odorous substances. The purpose of this work is the...

Комплексный подход в оценке экологического состояния городских почв

С.Г. Скугорева, Кутявина Т.И., С.Ю. Огородникова, Л.В. Кондакова, В.С. Симакова, А.Л. Блинова, Ю.Н. Зыкова, Л.И. Домрачева & Т.Я. Ашихмина
Впервые проведена оценка состояния городских почв вблизи одной из автомоек г. Кирова с использованием различных методов физико-химического, микробиологического анализа и фитотестирования. Полученные данные свидетельствуют о высоком уровне загрязнения почв нефтепродуктами, содержание которых превысило условно фоновое значение в 27–173 раза. Токсический эффект исследуемых урбанозёмов проявился в снижении каталазной активности, видового разнообразия фототрофов, диаметра колоний азотобактера, увеличении фитотоксичности по отношению к растениям ячменя и резком снижении численности живых клеток в популяции цианобактерии Nostoc paludosuт. Между данными показателями...
