Analysis of Surface Tension During Biodegradation of Hydrocarbons
Biodegradation of a model mixture of hydrocarbon (dodecane and hexadecane, 1:1 w/w), as well as hydrocarbon emulsified by synthetic and natural emulsifiers, and their mixtures were analyzed in the presence of Pseudomonas spp. and Bacillus spp. bacterial strains. Changes in surface tension were measured by the static and dynamic methods during biodegradation processes. During the biodegradation ...
متن کاملBiodegradation of Polycyclic Aromatic Hydrocarbons (PAHs) in Petroleum Contaminated Soils
Polycyclic aromatic hydrocarbons are a class of potentially hazardous chemicals of environmental and health concern. PAHs are one of the most prevalent groups of contaminants found in soil. Biodegradation of complex hydrocarbon usually requires the cooperation of more than single specie. In this research biotreatment of PAH (phenanthrene) was studied in a solid-phase reactor using indigenou...
متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Enzyme kinetics of multiple alternative substrates
An innovative theoretical approach that enables the complete characterisation of enzyme– substrate and enzyme–substrate–competitor reactions is generalised to systems with multiple alternative substrates. Based on the quasi-steady-state assumption, time-dependent closed form solutions are presented for cases with even, weak and mixed substrate competition. The analytic framework should facilita...
