A new organism belonging to the grey series of streptomycetes is described which produces 55 to 75 micrograms of daunomycin per ml in a sparged fermentor. This organism is not taxonomically related to other known daunomycin producers. Its proposed name in Streptomyces insignis ATCC 31913.
BACKGROUND Magnetotactic bacteria have long intrigued researchers because they synthesize intracellular nano-scale (40-100 nm) magnetic particles composed of Fe3O4, termed magnetosomes. Current research focuses on the molecular mechanisms of bacterial magnetosome formation and its practical applications in biotechnology and medicine. Practical applications of magnetosomes are based on their fer...
A solid state fermentation method was used to utilize wheat straw as substrates for citric acid production by using Aspergillus niger ATCC 9142. The Plackett Burman design (PBD) of experiments was used to test the relative importance of the variables affecting production such as moisture content, age of spore, inoculum size, initial pH of substrate, methanol conce...
Background and Objective: Haemophilus influenzae type b (Hib) is a gram negative bacterium and one of the most common causative agents of acute meningitis in infants and less than 5 years old children worldwide. The production of Hib capsular polysaccharide polyribosyl ribitolphosphate (PRP) is important for the production of conjugate vaccines against Hib infections. The aim of this study is t...
