Three monoclonal antibodies (MAbs) against nitrite oxidoreductase (NOR) of Nitrobacter hamburgensis were produced. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis and immunoblotting analysis of the purified enzyme showed that the MAbs named Hyb 153.1 and Hyb 153.3 both recognized a protein with a molecular mass of 64,000 Da, while Hyb 153.2 recognized a protein with a molecular mass o...
Females in a variety of taxa mate with more than one male during a single oestrus and exhibit mate preferences for genetically compatible males, but the influence of female mate choice on siring success is not clearly understood. Whether females choose to mate with more than one male or endure forced copulations is also often unknown. Here, we examined the effects of genetic relatedness on fema...
The effects of ultraviolet B (UV-B; 295-320 nm) radiation on certain vital physiological (photosynthesis), biochemical (production of reactive oxygen species - ROS) and behavioral (motility and orientation) characteristics were investigated in the unicellular photoautotroph, Euglena agilis Carter. The photosynthetic performance of E. agilis was recorded after exposure of between 15 and 60 min f...
The conditions present in both in vitro and in vivo ecosystems determine the microbial population harbouring it. One commonly accepted theory is that a species with a high substrate affinity and low growth rate (k-strategist) will win the competition against a second species with a lower substrate affinity and higher growth rate (r-strategist) if both species are subjected to low substrate conc...
In aerobic granular sludge (AGS), the growth of nitrite oxidizing bacteria (NOB) can be uncoupled from the nitrite supply of ammonia oxidizing bacteria (AOB). Besides, unlike for conventional activated sludge, Nitrobacter was found to be the dominant NOB and not Nitrospira. To explain these experimental observations, two possible pathways have been put forward in literature. The first one invol...
We report the draft genome sequence of Lactobacillus agilis strain Marseille, isolated from stool samples of a child suffering from kwashiorkor. This strain can use two metabolic pathways allowing the assimilation of glucose and xylose. Here, we present the first draft genome of the Lactobacillus agilis species.
Intestine samples of Bufo sp. tadpoles with parasitism confirmed for Giardia agilis were studied by transmission electron microscopy. The G. agilis trophozoites were long and thin. The plasma membrane was sometimes undulated and the cytoplasm, adjacent to the dorsal and ventral regions, showed numerous vacuoles. The two nuclei presented prominent nucleoli. The cytoplasm was electron-dense with ...
An analysis was made of the influence biotope temperature regime on body Lacerta agilis in local populations floodplain middle reaches Khoper river (Saratov region). The rectal active L. out-side their shelters shown to be 18.3–35.1°С and 18.2–34.8°С for males females, respectively. females spring period does not differ significantly. optimal agilis, which activity individuals is observed at, s...
Nitrate reductase induction by nitrate and repression by NH,+ has been studied extensively in the simple eukaryote Aspergillus nidulans (Pateman & Cove, 1967; Cove & Pateman, 1968). Wild-type cells grown on minimal medium, with 20m~-NaNO~ as the nitrogen source, rapidly lose nitrate reductase activity when transferred either to minimal medium without N (-N medium) or to minimal medium without C...
