Bacterial Profile of the Cotton Dust, from Cotton Grown in the Mississippi Delta Region, Collected for the Second Endotoxin Assay Round Robin Study

D. T. Chun and R. E. Harrison


 
ABSTRACT

Cotton dust was collected in 1998 on PVC (polyvinyl chloride) and glass filters from the 1997-Harvest year cotton grown in the Mississippi Delta region. The dust was collected using vertical elutriators from strict low middling (grade 41) cotton, low middling light spotted (grade 53) cotton, and a 1:1 mixture of the two grades of cotton. The bacterial profile of the cotton dust approximately 1 year after collection will be presented: this will include the population density as well as the most common bacterial genera found on the dust from the three cotton sources and the two filter types used for collection. Filter samples used to develop the profile will be from the surplus set of filters not used in the second endotoxin assay round robin study.
