Title: Isolation and characterization of Bacillus thuringiensis strains from Angola
Issue Date: 31-Dec-1996
Publisher: Elfos Scientiae
Citation: Biotecnologia Aplicada (ISSN: 0684-4551) Vol 13 Num 2
Abstract: Biotechnologia Aplicada 1996; Vol 13, No.2 B Paglietti, M Mura, G Scarpellini, I Pintus, A Satta, P Cappuccinelli, S Rubino and R Prota Code Number: BA96064 Sizes of Files: Text: 4.0K Graphics: No associated graphics files Bacillus thuringiensis is a sporigen bacterium widely distribuited in soil. During sporulation B. thuringiensis is characterized by production of parasporal crystals composed of protein molecules of different weights (27-140 KDa) known as delta-endotoxin or insecticidal crystral proteins that are toxic to various insects. In insects, after ingestion, delta-endotoxins are converted in smaller polipeptydes by proteases. The interaction between active toxin and the midgut epithelium causes pores in the cellular membranes of the epithelium and successively osmotic shock. Copyright 1996 Elfos Scientiae
