screening of3000 soil samples collected from cities of four different provinces of iran for starch-hydrolysing bacteria revealed that the nature is enriched with streptomyces species capable of producing amylolytic enzymes. among the bacterial isolates, one of the high starch-degrading strains was selected for further microbiological identification and also amylolytic enzyme(s) characterization...

background & objectives: campylobacter jejuni is a gram negative, microaerophilic, non-spore-forming and a small curved bacillus which is able to cause foodborne infection in human. in this study the occurrence of c. jejuni in poultry and beef meat was investigated. materials & methods: forty raw meat samples including 22 poultry samples and 18 beef samples were investigated for the presence of...

we investigated the microbiological quality of raw vegetables in mashhad, iran. in order to document the incidence of indicator and pathogenic microorganisms in this area. ninety eghit raw vegetable samples collected during 7 months were analyzed. all samples were examined for the presence of aerobic mesophilic bacteria, coliforms, enterobacteriaceae, escherichia coli, escherichia coli o157:h7,...

We concentrate on a family of discrete event systems obtained from a simple modular design principle that include in a controlled way primitives to deal with concurrency, decisions, synchronization, blocking , and bulk movements of jobs. Due to the functional complexity of such systems, reliable throughput approximation algorithms must be deeply supported on a structure based decomposition tech...
