Physiological And Biochemical Properties

The active strains of microorganisms capable of mobilizing phosphorus from sparingly soluble compounds were isolated from the vermicompost. Representatives of the genera Pseudomonas has dominated in association of phosphate mobilizing humus microbiota. The Pseudomonas sp. culture able to release the biggest amount of water-soluble phosphorus at vermicomposting of organic enriched with phosphorites was isolated. Basing on the analysis of morphological, cultural, physiological and biochemical properties studied strain was identified as Pseudomonas putida.

The data have been presented on physiological and biochemical properties (growth, acidogenic, proteolytic and antagonistic аctivity, resistance to NaCl) of lactic acid bacterial strains of Lactococcus lactis isolated from Belarus natural sources. These strains are promising for use as starter cultures for fermented dairy products, cheese.

Remediation Of Soil

Hexachlorocyclohexane (HCH) has been widely used in agriculture of our country to protect crops, vegetable fields, forest soils and plants from pests, and to treat scabies and other diseases in livestock. This pesticide is a highly toxic, carcinogenic, and banned substance that accumulates in human cells, tissues, and the environment over a long period of time. Incubated at 25°C for 3 days. The morphological, physiological, and biochemical characteristics of the two strains that differed in their biological properties and were dominant in the soil sample were determined. To determine the biochemical properties of these cultures, HCHDB1 (collection №1) culture was identified as 100% Bacillus circulans and HCHDB2 (collection № 2) culture was identified as 99% Brevibacillus brevis. Органик нэгдлээр бохирдсон хөрсийг микробиологийн аргаар цэвэршүүлэх боломж Гексахлорциклогексаныг манай улс хөдөө аж ахуйн салбарт өргөнөөр ашиглаж үр тариа, хүнсний ногооны талбай, ойн аж ахуйн хөрс, ургамлыг хортон шавжаас хамгаалах, мал амьтныг хамуу болон бусад төрлийн өвчнийг эмчлэхэд ашиглаж байсан. Энэхүү пестицид нь хүний эс, эд болон байгаль орчинд удаан хугацаагаар хуримтлагддаг, онцгой хортой, хорт хавдар үүсгэх нөлөөтэй, хэрэглэхийг хориглосон химийн бодис юм. Уг судалгаагаар гексахлорциклогексанаар бохирдсон хөрсний дээжинд илэрсэн бактерийн 12 омогийг 1%-ийн гексахлорциклогексан агуулсан хатуу (Nutrient agar) тэжээлт орчинд 25 хэмд 3 өдрийн турш өсгөвөрлөж ялган авсан. Биологийн шинж чанараараа ялгаатай бөгөөд уг хөрсний дээжинд доминант илэрсэн 2 омогийн морфологи, физиологи, биохимийн шинж чанарыг тодорхойлсон. Уг өсгөвөрүүдийн биохимийн шинж чанарыг тодорхойлоход HCHDB1 (коллекцийн №1) өсгөвөр 100%-иар Bacillus circulans, HCHDB2 (коллекцийн №2) өсгөвөр 99%-иар Brevibacillus brevis болохыг тус тус тодорхойлов.  Түлхүүр үг: гексахлорциклогексан, морфологи, физиологи, биохими, тэжээлт орчин
