Archaea are unique microorganisms that are present in ecological niches of high temperature, pH and high salinity. Archaea may be present freely or associated with plant rhizosphere. The plant-microbe interactions may be implicit to plants adaptation to abiotic stress of hypersalinity. With an aim to look for population dynamics of archaea at different seasons of the year in hypersaline environments...
In the present study, physiological and biochemical responses of Dunaliella salina exposed to acrylamide were investigated. The indicators were as follows: the growth, photosynthetic pigments, the contents of carbohydrate and protein, antioxidant system of Dunaliella salina. Besides, the ultrastructure and cell cycle distribution were also analyzed. The results showed that acrylamide could significantly...
Allelopathic inhibition activity of Spirogyra and Ceratophyllum demersum (C. demersum) on Microcystis aeruginosa were compared using a series of experiments. Culture solution of Spirogyra was found to inhibit growth of M. aeruginosa resulting in the destruction of chlorophyll-a and increased MDA content of the algae. The inhibitory effect was increased with greater concentrations of macrophyte culture...
Antimicrobial resistance is one of the major threats faced in aquaculture systems. Hence the present study is mainly focused on to determine the antimicrobial susceptibility associated with pathogens derived from diseased freshwater ornamental guppy fishes. Around fifteen isolates were resolved from the infected fishes and subjected to antimicrobial susceptibility testing, phenotypic and genotypic...
Microorganisms enriched from activated sludge were found to attach to phosphate rock (PR) through biofilm formation. In the present study with a column bioreactor, the microorganisms both in biofilm and solution were characterized by Illumina high-throughput sequencing. The results from Illumina 16S rRNA gene MiSeq analysis revealed Alphaproteobacteria being the dominant bacterial group at the class...
Documentation of avian assemblages in different ecosystems is very important from environmental monitoring perspective. We assessed the species richness and foraging guilds of birds in different habitats of a suburban area in lower Gangetic plains (Bongaon, West Bengal, India) where no such studies have been done so far. Overall, 119 species of birds were recorded during the study period (June 2015...
Echinacea purpurea L. (2n = 2x = 22), is one of the most popular medicinal plants in developed countries containing important secondary metabolites including caffeic acid derivatives, amongst which chicoric acid is the most significant. Chicoric acid has positive effects on human immune system. Hairy roots culture of E. purpurea is an efficient method for producing chicoric acid, because of their...
The aim of this study was to evaluate the spatio-temporal variation and influence of environmental factors on the reproduction of H. pudibundus, and to estimate the size at the onset of sexual maturity (CW50). Samples were taken monthly from January to December 2000 in nine transects ranging from 2 to 40 m of depth. Bottom temperature, salinity, and sediment texture were recorded at each transect...
Withaferin-A (WA) is a major bioactive compound in the roots of Withania somnifera. It is reported to possess inhibitory effects against breast cancer, liver cancer, melanoma cancer and prostate cancer cells. We developed an elicitation based on the hairy root culture (HRC) protocol for the enhancement of the WA production. Agrobacterium rhizogenes strain R1000 was used for the establishment of hairy...
Silicon is considered to be a beneficial element for plants, improving their potential to overcome various stress conditions. Accumulation of silicon differs across different plant species and during plant development, leading to differences in their sensitivity to environmental constraints. We studied the leaf contents of silicon and some other elements for barley (Hordeum vulgare L.) and spelt (...
The aim of the study was to investigate the effect of pine needles and vitamin E powder on blood biochemistry and carcass characteristics of female Japanese quails. A total of 180 female Japanese quails were obtained from the open market and maintained at deep litter housing pens system for 42 days. After adaptation, all female quails were divided into the following groups, group 1, control QC; group...
In this study, we focused on the potential production of descendant ramets in sexual, asexual, and mixed ramet clusters of Solidago ×niederederi Khek (Asteraceae), a natural hybrid between the North American S. canadensis and the European S. virgaurea. We selected eight populations of the hybrid occurring in southern Poland. The ANOVA results proved the significant effect of cluster type and population...
The type specimens of Hydnobius punctulatus Hampe, 1861 were examined, redescribed and illustrated. Lectotype as well as paralectotypes were fixed by inference. The species is characterised by the form of the aedeagus with sinuate parameres and by the wide and pale antennal club. Variability is commented on basis of additional material collected in Slovakia. Records from Slovakia represent the northernmost...
The relationships between the distribution and diversity patterns of benthic invertebrates in forest ponds used for different recreational activities were examined in this study. The study was based on sampling of benthic invertebrates, plant coverage, physical and chemical analysis of water samples and multivariate species analysis. Mining ponds varied in their solution chemistry and plant cover,...
