OBJECTIVES Recombinant protein production processes in Escherichia coli are usually operated in fed-batch mode; therefore, the elaboration of a fed-batch cultivation protocol in microtiter plates that allows for screening under production like conditions is particularly appealing. RESULTS A highly reproducible fed-batch like microtiter plate cultivation protocol for E. coli in a micro-bioreac...

Batch and fed-batch cultivation of Bacillus thurillgiellsis var. kurstaki was carried out to achieve high cell and spore density with maximum insecticidal activity. Cell cultivation was done in fully equipped fermentors under controlled conditions at different feed rates. Increased cell mass, high spore counts and improved insecticidal activity were achieved with fed-batch cultivation system. W...

abstract soil compaction is a main factor that reduces the cane yield in sugarcane fields, in southwest of iran, especially in ratoon cropping system. therefore, sub-soiling practices could alleviate adverse effects of compaction and increased yield. in according to this aim, a study was to evaluate the effect of  ratooning practice systems consisting of control (no subsoiler), two and four sha...
