Draft Genome Sequence of Bacillus sp. Strain CDB3, an Arsenic-Resistant Soil Bacterium Isolated from Cattle Dip Sites
Bacillus sp. strain CDB3, isolated from cattle dip sites in Australia, is highly resistant to arsenic. It contains 22 arsenic resistance (ars) genes, of which 17 are organized in 3 ars clusters. Here, we report the draft genome sequence of CDB3, which will assist us in understanding the overall ars mechanism.
متن کاملSpeciation and absolute bioavailability: risk assessment of arsenic-contaminated sites in a residential suburb in Canberra.
Watson is a fully developed suburb of some 30 years in Canberra (the capital city of Australia). A plunge dip using arsenical pesticides for tick control was operated there between 1946 and 1960. Chemical investigations revealed that many soil samples obtained from the study area contained levels of arsenic exceeding the current health-based investigation levels of 100 mg kg-1 set by the Nation...
متن کاملArsenic status and distribution in soils at disused cattle dip in South Africa.
The status and the distribution of arsenic in soils from a disused cattle dip were determined. Elevated total arsenic levels (1,033-1,369 mg/L) were detected in the soils. Significant difference (p < 0.05) between the values for the soils obtained from the contaminated sites and control site (0.15 mg/L) was observed. The level of total arsenic decreased with increase in depth. The peak total ar...
متن کاملArsenic speciation and distribution in an arsenic hyperaccumulating plant.
Arsenic-contaminated soil is one of the major arsenic sources for drinking water. Phytoremediation, an emerging, plant-based technology for the removal of toxic contaminants from soil and water, has been receiving renewed attention. Although a number of plants have been identified as hyperaccumulators for the phytoextraction of a variety of metals, and some have been used in field applications,...
متن کاملAssessment Effect of Organic Matter and Arsenic on Transfer Coefficient, Tolerance Index and Phytoremediation in Cress (Lepidium sativum L.)
Soil contamination with heavy metals such as arsenic has harmful effects on human health and agricultural products. Arsenic (AS) is one of the heavy metals which are highly toxic and carcinogenic. This research was conducted to study the effect of organic manure on increasing the Arsenic absorption ability by Cress plant in the greenhouse of the Agriculture and Natural Resources Research Center...
