“…Biodegradation of TOPW coupled with Aspergillus growth induced 64%, 62 % and 48 % of COD, color and phenolic compounds removals respectively after four days of culture.This high removal efficiency could be attributed to both degradation and adsorption of phenolic compounds. In somewhat analogous studies, Hamdi et al [28] reported that the decreased color intensity of the olive mill wastewater was possibly due to both the degradation of some phenolic compounds and the adsorption of the polyphenols and tannins onto the fungal mycelium. Moreover, Andleeb et al [9] showed that the high percentage of the decolorization of dyes by Aspergillus niger is due not only to microbial biotransformation but also to biosorption.…”

Aspergillus niger has been tested in a discontinuous process for the pretreatment of fresh green Table Olive Processing Waste waters (TOPW). The influence of seven factors like incubation time, initial pH, dilution, glucose, agitation, (NH 4 ) 2 SO 4 and inoculum size on decolorization was screened by employing a fractional factorial design 2 7-4 . Through factorial plots and analysis of variance, it was found that only glucose and agitation affected the decolorization. Further studies were carried out to adjust the level of determinant factors. Results showed that color removal (62%) was optimum at 150 rpm and 3 g/l glucose. HPLC and FTIR analysis of the treated TOPW suggested that the decolorization occurs through biosorption and biodegradation. Tannase and lignin peroxidase were detected in the cultures. However, only tannase is responsible for the color removal of the TOPW because lignin peroxidase is produced at a low level. Data are reported as mean ± standard deviation of results carried out in triplicate Characteristics

Article InfoFungi have been reported to play an important role in bioremediation processes. Hence the study was attempted using fungi to analyse the bioremediation effect. Results show that pH levels were found to decrease between 7.3 to 7.8 while nitrate levels decreased between 69.9 to 84% and phosphates between 79.2 to 83.4%. The BOD and COD levels showed reduction between 78.6 to 89.4% (BOD) and 82.6-85.6% (COD). Nevertheless, the maximum reduction was noticed in the setup which contained the consortium of organisms probably showing a synergistic effect.

Current and previous studies on bio-based (fruit) wastes and wastewaters, with a particular emphasis on research in South Africa, were reviewed. Previous studies have focused predominantly on the beneficiation and application of fruit waste as a feedstock for renewable energy. A definite gap in knowledge and application of fruit waste streams with regard to enzyme production as a value-added product is identified. The characteristics and composition of each type of fruit waste are highlighted and their potential as feedstocks in the production of value-added products is identified. The conversion of agri-industrial wastewaters to bioenergy and value-added products is discussed, with special mention of the newly published South African Bio-Economy Strategy, and the potential production of biofuels and enzymes from waste streams using recombinant Aspergillus strains. Finally, to maximise utilisation of waste streams in South Africa and abroad, a conceptual model for an integrated system using different technologies is proposed.
