| Abstract | Bacillus thuringiensis is a well-known species of entomopathogenic bacteria that is widely used as a biopesticide against many insect pests. Insecticidal proteins, coded for by genes located in plasmids, form typical parasporal, crystalline inclusions during sporulation. In this report, an unusual strain of B. thuringiensis subserovar oyamensis (LBIT-113), isolated from living larvae of Anopheles pseudopunctipennis in Mexico, was characterized by its ultrastructure, the protein composition of its parasporal crystal, plasmid pattern, and toxicological properties against several insect and noninsect targets. The parasporal crystal is enclosed within the spore's outermost envelope (exosporium), as determined by transmission electron microscopy, and exhibits a square, flat shape. Its main components are two proteins with sizes of 88 and 54 kDa. Despite some crystal morphology resemblance, both proteins are immunologically unrelated to the Cry IIIA protein, as shown by immunoblot analysis, when probed with antisera raised against the 88-kDa protein and the Cry IIIA protein. Partial N-terminal sequence of the 88-kDa protein revealed a unique amino acid arrangement among the Cry proteins. Solubilization of the crystal proteins was achieved at 3.3 M NaBr, and its digestion with trypsin showed only one ca. 60-kDa peptide, as observed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The patterns of three plasmids of strain LBIT-113 were considerably different from those of B. thuringiensis subspp. kurstaki, tenebrionis, and israelensis. Parasporal crystals showed no toxicity to larvae of four species of caterpillar, three species of mosquito, two species of beetle, one species of cricket, one species of ant, one species of aphid, one species of nematode, one species of ostracod, one species of ameba, and one species of rotifer. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
