Sterile peat used as biofilter medium, was amended with four different concentrations of a nutrient solution, inoculated with a toluene-utilizing consortium. Samples were incubated over 120 days in closed environments microcosms with water vapor and toluene saturation to emulate the conditions prevailing in biofilters. An improvement on toluene consumption rates, associated with microbial growt...

The effect of salinity and nitrogen on yield, vitamin C, citric acid and nutrient distribution of tomato in hydroponics culture was investigated. Tomato seeds were first let germinate in yonolit pots with wet coco peat and then their seedlings were transferred to plastic tanks containing 5 liters nutrient solution. Treatments were three levels of salinity (0, 30 and 60 mM as NaCl and CaCl2) and...
