متن کاملSCREENING FOR STARCH-HYDROLYSING BACTERIA
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) characteriza...
متن کاملMagentotactic bacteria and their applications
Magentotactic bacteria are the types of bacteria capable of orientation in an external magnetic field because of the ability to produce structures called magnetosomes. Magnetosomes, nanometer-scale structures, are present in most of the magnetotactice bacteria. They are intracellular organelles composed of magnetic iron mineral crystals individually surrounded by a phospholipid layer. Because o...
