ABSTRACT
The distribution of mycoflora inhabiting bird's feather was studied. All the fungi were screened
for keratinolytic activity. Chrysosporium spp having high keratinase activity was taken for
further studies. The biochemical changes during biodegradation of transgenic poultry feathers
were studied. Bacillus sp, was also included for rapid degradation of poultry wastes. The
keratinase from Chrysosporium spp., was purified and homogeneity was confirmed by
polyacrylamide gel electrophoresis

Abstract

Songbirds apply ants to their feathers during anting behavior, possibly as a method of reducing
feather parasites. We tested polar and nonpolar ant secretions and pure formic acid for
bactericidal and fungicidal effects on microbial ectoparasites of feathers. Microbial inhibition
trials were run with the bacteria Bacillus licheniformis (strains OWU 138B and OWU 1432B)
and B. subtilis; and with the fungi Chaetomium globosum, Penicillium chrysogenum, and
Trichoderma viride. Ant chemicals were derived from Camponotus pennsylvanicus, Pheidole
dentata, Aphaenogaster rudis, Crematogaster lineolata, and Lasius flavus worker-caste ants.
Although pure formic acid strongly inhibited all bacteria and fungal hyphae tested,
concentrations of formic acid found in the bodies of formicine ants did not. Neither hexane ant-
chemical extracts nor ant suspensions in deionized water inhibited the microbial species.
Consequently, the hypothesis that birds apply ants to control feather parasites was not supported.
