Several varieties of heat-sterilized broiler litter with 60% (wet basis, wb) moisture content were substrate in solid-state fermentations to produce biocontrol agents. Litter varieties included litter produced by one flock of broilers from medicated and non-medicated controlled rations, and litter produced by two flocks and four flocks on a single application of bedding material from medicated commercial...
Broth for the growth of Bacillus thuringiensis subsp. kurstaki was prepared by extraction of broiler litter with water. Filamentous growth occurred during the first 6 h of fermentation in the full strength and in a 2:1 extract dilution. Of the five dilutions examined, the 2:1 dilution of the extract having a total organic carbon concentration of 1.7 g/l produced the highest spore count, 2.46 x 10...
