This article provides a study of the molecular, physiological, biochemical and morphological features of R-, S- and M-dissociants of Rhodococcus ruber - 8/4/1. The sequence similarity of the genome fragments of R- and S-dissociant forms encoded by 16S rRNA was demonstrated. MALDI spectra were obtained for the R. ruber-8/4/1 strain and its dissocian...

In this review, the data on the use of bacteria of the genus Rhodococcus in the biocatalytic synthesis of amides and other compounds by biotransformation of the corresponding precursors have been presented. An adaptation ability of these bacteria to various extreme environmental conditions, the synthesis of different enzymes and the participation i...

Aims: The study is to characterize the local strain of Rhodococcus sp.-3/4/3, isolated from environmentally polluted wastewater, to study the ability of the strain to synthesize BS. Methodology and results: The natural strain of Rhodococcus sp.-3/4/3, a biosurfactant (BS) producer, was isolated from the polluted wastewater of Navoiyazot JSC. Based...

This paper describes an express method, which has been developed for the primary screening of the acid-forming mycelial fungi belonged to Aspergillus and Penicillium genus on selective solid nutrient (SSN) medium. It was established that eight strains of mycelial fungi had the highest acid-forming ability on SSN medium among the isolated 63 natural...

https://doi.org/10.5281/zenodo.8368209 Abstract. In order to select bacteria, producing thermostable α-amylase, 62 isolates isolated from soil samples of Kashkadarya, Samarkand and Tashkent regions have been screened for starch hydrolysis properties. As a result, 8 bacterial strains belonging to the genus Bacillus were selected as potential α-amy...

https://doi.org/10.5281/zenodo.8372639 Аbstract.The wide application and development of effective technologies for the production of industrial enzymes with the help of microorganisms attracts a growing number of researchers in this field. The aim of the present work was to screen bacteria of the genus Bacillus from the local collection of the Ins...

This article presents the results of a study on the possibility of intensifying the process of destruction of oil and oil products by a balanced methanogenic association of microorganisms (obtained after fermentation under thermophilic conditions) (BTMAM) by introducing into them a strain of the bacterium Rhodococcus sp. HN4. The amount of inoculum...

21 века. Их значение на мировом рынке растет: сегодня рынок биоПАВ оценивается в 2374 млн долл. США, и по прогнозам в течение 2022-2027 гг. среднегодовой темп роста составит более 5,5 % [1, 2]. В настоящее время проводятся много-численные исследования по выделению биоПАВ из различных микроорганиз-мов, однако бактерии рода Acinetobacter заслуживают...

In the experiment, bacteria were isolated from soil contaminated with oil residues and identified in a MALDI TOF mass spectrometer. The characteristics of the formation of biological surfactants were studied in the separated samples according to the emulsification index. The growth of the samples in nutrient media with different carbohydrate source...

The research on studies of the various gamma-irradiation doses effect for survival and ability of mutant strains to synthesize biosurfactants has been conducted. It was shown that gamma-irradiation with inducing dose in 2-3 kGr for bacteria of the genus Rhodococcus, more than 1.4 times increasing of biosurfactant biosynthesis and surviving of cells...

In order to isolate active strains of microorganisms, producers of biosurfactants, oil sludge and smeared wastewater samples of the Bukhara refinery plant and oil-gas wells of Kashkadarya region were used. As a result, 29 strains of bacteria belonging to the genus Bacillus have been isolated in pure culture. The totality of data obtained during the...

Partially purified enzyme preparation with specific activities of 153.7 U/mg for α-amylase and 0.15 U/mg for protease was produced by selective adsorption on starch. Enzymes were purified until homogeneous electrophoretically by gel-filtration over HW-55 TSK-gel with specific activities of 245 U/mg for α-amylase and 1.44 U/mg for protease. The opti...
