Comparison of optical density, total cell protein, and number of viable cells (via fluorescent straining) as measures of microbial growth kinetics in suspended and biofilm cultures during biodegradation of naphthalene
… considerable uncertainty in reliably predicting rates of biodegradation for design of treatment processes for environmental pollutants. This research focused on measurement of bacterial growth rates and activities in suspended cultures and biofilms using Pseudomonas putida (ATCC 17484) for …

DEVELOPMENT OF BIO-ACTIVE FOOD PACKAGING FILMS
… for grapefruit seed extract (GSE). The influence of molecular weight (MW) of chitosan on the blend was investigated. Lower MW chitosan accelerated the release of GSE that led to significant improvement in plasticization, hydrophilicity and inhibition of the growth of Escherichia coli. Albeit it …

A statistical approach to assess the efficiency of bioremediation methods
There are a number of Superfund sites in which biotreatability studies are used to assess whether an addition of some surfactants have a positive effect on the rates of biodegradation of PAH concentrations when compared to a control. U.S. EPA, in many situations, will require a minimum of 40% …

Bioremediation of modelled petroleum-contaminated soils of the Niger Delta and the impact of zeolite augmentation
The bioremediation of modelled petroleum oil-contaminated soils of the Niger Delta by a mixed culture of three hydrocarbon-degrading bacteria, Acinetobacter sp, Rhodococcus sp and Pseudomonas sp, was investigated. These bacterial strains were selected based on criteria that they were able to …

Assessment of Microbial Biodegradation of Mixed Soil Contaminants at the Santa Susan Field Laboratory Using TRFLP, qPCR, and Culturing
<p>The potential for biodegradation of contaminants in soil was assessed using an array of molecular methods, including terminal restriction fragment length polymorphism (TRFLP), quantitative polymerase chain reaction (qPCR), and traditional culturing techniques combined with sequencing of the 16S …
