As a result of rapid expansion of the industrial sector and increasing population, the environment has been under phenomenal stress. The volume of sewage and other effluents has increased tremendously in the last century. Globally, approximately .12 million tonnes of dry sludge biomass is produced and discarded of by landspreading, landfilling, incineration or dumping in lagoons and oceans. The discharge of industrial effluents into receiving waters has been documented to be the cause of severe environmental contamination. Heavy metals have been the cause of particular environmental concern. Their toxic and carcinogenic potentials at low concentrations, as well as the large quantities disposed to the environment, have prioritised them as leading contaminants. Current technologies of remediating heavy metal containing effluents are expensive and, in most cases, ineffective. Locally, most industries are merely diluting their effluents, thus resulting in the loss of valuable water resources. Waste sludges have shown the ability to adsorb heavy metals from their aqueous environment. Therefore, the current study attempted firstly, to compare biosorptive capacities of various waste sludges for a range of heavy metal ions, and secondly, to establish a relationship, if any, between biosorptive capacity and sludge surface charge. Finally, a laboratory scale biosorption process, encompassing desorption and recovery of metal ions from sludge surfaces, would have to be developed. Effluents used included pure, metal solutions of divalent zinc, cadmium, copper, nickel, trivalent and hexavalent chromium. In addition, synthetic effluents comprising a cocktail of the above-mentioned metal ions as well as an industrial effluent from a metal plating company were used. Five waste digested sludges were prepared and challenged against pure metal solutions to determine and compare their respective biosorptive capacities. Mechanisms of biosorption were elucidated using the Langmuir adsorption isotherm model. Sludge surface charge was determined using the millivolt quantification method. Upscaling of bioreactor trials to fully mixed laboratory scale was also investigated. These experiments encompassed the use of three sludges showing the greatest potential for biosorption and desorption using the selected mineral acid, H2S04, In addition, a simultaneous fully mixed biosorption and desorption process was designed and optimised. Subsequent trials involved comparing the latter process with a packed bed configuration whereby biomass was immobilised using poly sulfone resin. The overall comparative adsorptive capacities of the sludges (SI-SS) for metal ions in single solutions was S3 > S2 > S4 > SS > SI. Surface charge determination showed S3 to contain the most electronegative charge, with other sludges following in the same descending order as mentioned above. These findings…

The purpose of this investigation was to determine the effect of Colibacillinum and co-trimoxazole in terms of it's effect on the growth rate and cellular morphology of E. coli in order to contribute towards the understanding of the use of Colibacillinum in E. coli infections. The strain of E. coli used in this study was isolated from a patient with cystitis. The experiment consisted of 2 trials. During the first trial, E.coli was tested for sensitivity to co-trimoxazole. The method of choice was the serial-dilution-agar-plating procedure. Samples were removed Oh, 6h, 12h, 24h and 48h after inoculation, serially diluted' and incubated for 24h. During the second trial, E. coli was tested for sensitivity to Colibacillinum 5CH, 7CH, 9CH, 12CH and 15CH by employing the method stated above. From the data obtained the growth rate, specific growth rate, maximum cell population reached and lag phase were computed. Colibacillinum 7CH proved to be the most effective potency, of the various potencies tested. Colibacillinum 7CH reduced the maximum population by 41.5% and cotrimoxazole reduced the maximum population by 97% relative to the maximum population of the control. The maximum specific growth rate of the E.coli treated with Colibacillinum 7CH increased by 0.609% and that treated with co-trimoxazole decreased by 67.33% when compared to the maximum specific growth rate of the control. The in vitro results indicate that co-trimoxazole is a far superior bacteriostatic chemotherapeutic agent than Colibacillinum. This is further supported by the changes in cellular morphology observed during scanning electron microscopy. The E. coli treated with co-trimoxazole was found to be shorter in length and irregular when compared to E. coli treated with Colibacillinum 7CH. Definitive conclusions could not be drawn from the results therefore Colibacillinum cannot be recommended as a front line agent in the treatment of cystitis. It's use in the treatment of E. coli infections, in conjunction with other forms of treatment, either homoeopathic or allopathic, may only be recommended once further studies have been conducted.
