“…In the CE case, BOD, COD and TON were reduced by 3, 1.6 and 40.9%, respectively and in the case of ChE, BOD and TON were reduced by 3 and 50%, respectively. The findings of the present study are in agreement with those reported by Mueller et al [21] who found that a complete assimilation of carbon compounds into biomass is not achievable under natural conditions, due to the fact that some compounds are recalcitrant or are metabolized slowly over long periods.…”

Some effluents ((Whey Effluent (WhE); Orange Effluent (OE); Carrot Effluent (CE) and Chocolate Effluent (ChE)) were bioremediated using some allochthonous microorganisms (Lactobacillus delbrueckii subsp. bulgaricus, Saccharomyces cerevisiae Y-1347 and Dekkera bruxellensis). The highest biodegradable efficiency of the Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD) and Total Organic Nitrogen (TON) of the effluents under investigation was noticed when using the allochthonous microorganisms together with the autochthonous one. Saccharomyces cerevisiae Y-1347 proved to be the best utilizer of Whey (WhE) organic and nitrogenous compounds with the reduction of BOD, COD and TON by 12.36, 20.09 and 68.42%, respectively. Dekkera bruxellensis proved to be the organism of choice on using Orange Effluent (OE) where BOD, COD and TON were reduced by 18, 20 and 53.39%, respectively. Lactobacillus delbrueckii subsp. bulgaricus proved to be the best utilizer of the Carrot Effluent (CE) constituents by reducing BOD, COD and TON by 24.27, 19.33 and 63.63%, respectively. Dekkera bruxellensis proved to be the best utilizer of the Chocolate Effluent (ChE) constituents by improving its quality and reducing BOD, COD and TON by 18.36 and 15.86 and 73.07%, respectively. A successful trial was made to use the treated effluents in the irrigation of Lens culinaris and Phaseolus vulgaris seeds for germination.

“…Because of these properties, PAHs have been included in the U.S. Environmental Protection Agency's list of priority pollutants. The removal of PAHs from soil is necessary during soil remediation to comply with relevant cleanup standards and is based on individual PAH standards (4,14,22,33).…”

“…It has been applied to a variety of soils and contaminant types (i.e., creosote, coal tar, petroleum) and is generally preferred over non-biological approaches such as stabilization, chemical oxidation and incineration (Mueller et al, 1995). The focus of landfarming is to stimulate the degradation capabilities of natural microbial communities by providing oxygen and nitrogen, and to use physical mixing of the soil to distribute the contaminants over a greater surface area and bring them into contact with the microorganisms.…”
