background; the aim of this study is to compare uv, ferrate (vi) and uv/ferrate (vi) methods for removal of hydrogen sulfide and chemical oxygen demand (cod) from municipal wastewater under a continuous condition. methods; the experiment was divided into three parts: 1) pollutants removal by using ferrate (vi) alone; 2) pollutants removal using uv alone; 3) pollutants removal using a combinatio...

Pantoea ananatis AMG 501 is a plant growth-promoting bacterium isolated from rice leaves. Its genome was estimated at 5,102,640 bp with 4,994 coding sequences, encompassing genes related to the metabolism of carbohydrates, to the synthesis of auxins, siderophores, and homoserine lactones, and to the type I, II, III, IV, and VI secretion systems.

The experiment was conducted taking Fifteen genotypes of sweet potato were evaluated in RBD with three replications during kharif season 2019 & 2020 at the K.V.K Dhenkanal District ,Odisha. Among characters studied, different high PCV and GCV observed for like vine length, internodal number branches per plant, leaves total leaf area, roots root yield β-carotene content, starch sugars, reduc...

Extensive industrial activities resulted in an increase chromium (Cr) contamination the environment. The toxicity of Cr severely affects plant growth and development. is also recognized as a human carcinogen that enters body via inhalation or by consuming Cr-contaminated food products. Taking consideration enrichment environment its toxic effects, US Environmental Protection Agency for Toxic Su...

Epigenetic gene silencing by aberrant DNA methylation of gene promoter regions is a nonmutagenic but heritable epigenetic mechanism that may mistakenly cause the silencing of important cancer-related tumor suppressor genes. Using a transgenic, V79-derived, mammalian cell line (G12) that contains a bacterial gpt reporter gene in its DNA, we can study carcinogen-induced gene inactivation by mutag...

Vibrio owensii GRA50-12 was isolated from symbiotic green algae of coral. The genome contains genes encoding toxin production, virulence regulation, stress response proteins, types II, IV, and VI secretion systems, and proteins for the metabolism of aromatic compounds, which reflects its pathogenic potential and its ecological roles in the ocean.

Research Objectives: Microbiological reduction and immobilization of U(VI) and Tc(VII) has been proposed as a strategy for remediating radionuclide-contaminated environments. Numerous studies focusing on the reduction kinetics and speciation of these metals have been carried out using contaminated sediment samples, microbial consortia, and pure bacterial cultures. While previous work with model...

On the contrast to the well known, that there are other different genes involved in symbiotic nitrogen fixation in addition to nod, nif and fix genes. In this review we will discuss up to date the function of genes that can play a significant role in symbiotic N fixation such as nodulation, nitrogen fixation, production of 2 exopolysaccharides, Type I to Type VI secretion systems and other diff...

Chromium through natural processes and human activities enters the air, soil and water. Chromium-resistant bacteria are capable of reducing toxic Cr(VI) to less toxic Cr(III). In this work, batch studies were conducted to evaluate the effect of environmental factors on the rate of Cr(VI) reduction from synthetic wastewater of metal plating industry by Bacillus cereus under aerobic conditions. T...
