Characteristics and the use as culture media of protein hydrolysate from Locusta migratoria were determined in comparison with different peptones. After powdering, it was hydrolyzed chemically (acid hydrolysis) obtained product Locust Peptone (LP). The contents protein, fat, nitrogen, ash, minerals, total sugars amino acids LP seen that has both organic inorganic materials enough to a component...

INTRODUCTION Many insects possess two types of eye: a compound eye and a simple eye or dorsal ocellus. Much work has been done on the powers of vision in insects, and it is known that these are almost entirely due to the presence and form of the compound eye. The perception of form and colour, and the appreciation of movement in the visual field, are its recognized functions. No such clearly de...

The complete amino acid sequence of a structural protein, protein 8, isolated from the pharate cuticle of the locust Locusta migratoria was determined. Protein 8 contains 148 amino acid residues and has an Mr of 15,224. By the extensive use of information obtained by plasma-desorption mass spectrometry (p.d.m.s.) it was possible to reduce the need for conventional sequence determination and to ...

Global warming is currently of great concern. Yet the ecological effects of low-frequency climate variations remain largely unknown. Recent analyses of interdecadal variability in population abundance of the Oriental migratory locust (Locusta migratoria manilensis) in China have revealed negative associations with temperature and positive associations with Yangtze drought and flood frequencies ...

Escherichia coli K1 infection is a major cause of neonatal meningitis, with high rates of mortality and disability. Despite years of research, only a small number of factors contributing to E. coli K1 virulence have been identified. The Tat (twin-arginine translocation) protein export system is found in the cytoplasmic membrane of E. coli and is involved in the transport of folded proteins. In ...
