The diversity of fungi, bacteria, yeast, actinomycetes and protozoa were analysed in the gut and casts of Eudrilus eugeniae, Lampito mauritii, Eisenia fetida and Perionyx excavatus, both qualitatively and quantitatively as influenced by different feed substrates like clay loam soil, cowdung and pressmud. While actinomycetes (Streptomyces albus, S. somaliensis, Nocardia asteroides, N.

The effect of glucose oxidase (GOX)-catalase with different GOX-catalase ratios and of the Chemicals produced by GOX, gluconic acid and hydrogen peroxide, were evaluated on four microorganisms usually present in shrimp. Growth inhibition was independent of the enzyme ratio within the limits tested. Hydrogen peroxide inhibited Pseudomonas fluorescens , Hansenula polymorpha and Acinetobacter calcoaceticum .

LPS and lipid A were also prepared as reference compounds from Escherichia coli UKT-B.
