Three bacteria from a tobacco industry effluent and one from a sewage sample were isolated on a medium comprising of 1% tobacco powder as sole source of nutrients. Bacteria isolated from the industrial waste water were identified as Bacillus cereus, B. alvei and B. circulans. While, Lactobacillus sp. was isolated from the sewage sample. The bacteria were optimized for various growth conditions ...

Tomato polygalacturonase is a cell wall enzyme secreted in large amounts during tomato fruit ripening. Polygalacturonase is synthesized as a glycoprotein precursor that undergoes numerous cotranslational and post-translational processing steps during its maturation, yielding three isozymes in tomato fruit, PG1, PG2A, and PG2B. To investigate the physiological roles of the three isozymes and the...

Although most research on the effect of tobacco warnings has been focused on attitude changes following the presentation of tobacco warnings, this paper takes a somewhat new perspective by investigating cognitive processing of tobacco warnings by adolescents of different ages (i.e., 14-, 16-, and 18-year-olds). More specifically, this paper investigates the way adolescents encode different text...
