Biofilm Forming Bacteria during Thermal Water Reinjection

Persistence of non-native spore forming bacteria in drinking water biofilm and evaluation of decontamination methods.

Persistence of Bacillus globigii spores, a surrogate for Bacillus anthracis, was studied on biofouled concrete-lined slides in drinking water using biofilm annular reactors. Reactors were inoculated with B. globigii spores and persistence was monitored in the bulk and biofilm phases, first in dechlorinated water and later with free chlorine concentrations of 1 and 5 mg/L. In the dechlorinated s...

Susceptibility of drinking water biofilm bacteria to sodium hypochlorite

Study of biofilm in bacteria from water pipelines.

CONTEXT A biofilm is a layer of microorganisms contained in a matrix (slime layer), which forms on surfaces in contact with water. Their presence in drinking water pipe networks can be responsible for a wide range of water quality and operational problems. AIM To identify the bacterial isolates, obtained from water pipelines of kitchens, to evaluate the water quality & to study the biofilm pr...

A New Method of Forecasting the Thermal Breakthrough Time During Reinjection in Geothermal Reservoirs

Success of a reinjection process depends on the method used for estimating the thermal -ugh time. Estimating the thermal breakthrough time may be based solely on tracer data. Alternatively. it may be estimated solely by using thermal interference tests. While the tracer method usually yields ambiguous estimates, thermal interference tests are infeasible because durations of these tests are simi...

Draft Genome Sequences of Biofilm-Forming and Non-Biofilm-Forming Nontyphoidal Salmonella enterica Serovars

The genetic basis for biofilm formation among nontyphoidal salmonellae (NTS) remains poorly understood. This draft genome submission provides initial insights on the genetic differences between biofilm-forming and non-biofilm-forming clinical and environmental NTS serovars.
