A Proteinase Produced by Pseudomonas aeruginosa Isolated from Chilo Suppressalis

Abstract

A Proteinase Produced by Pseudomonas aeruginosa Isolated from Chilo suppressalis Sir: A crystalline proteinase was obtained from culture broth of Pseudomonas aeruginosa isolated from Chilo suppressalis. Cultivation and purification were carried out as follows: Ps. aeruginosa was cultured in 2000 ml of glucose-bouillon medium. The medium was contained in shaking flasks of 5000 ml volume, which were placed on a rotary shaker and incubated at 28•`30•Ž for 2 days.

A Disease of Pale Western Cutworms (Lepidoptera: Noctuidae) Reared in the Laboratory

“…Toxins that could be produced by the microorganisms associated with the insect or its food may also be involved. For example, under certain conditions P. aeruginosa produces exotoxins (Amonkar et al 1967;Ogino et al 1970), which could contribute to symptoms of the disease. Furthermore, mycotoxins (Wogan 1966) produced by some common fungi are toxic to insects (Prasertphon 1967;Yendol et al 1968).…”
