Compost-derived liquid fertilizers are uncostly and nutrient-enriched; however, its dark brown appearance limits light uptake of microalgae during autotrophic cultivation. Here, integrated UV irradiation/ozonation pretreatment was employed to decolourize the compost solution prior Aforesaid could accomplish 16.52 % (8 h) or 40.88 (24 decolorization efficiency by using optimal parameters (initia...

Sacha inchi (Plukenetia volubilis) shell is a potential source of phenolics with an-tioxidative activity and its extract can be used to prevent lipid oxidation in some food matrices. However, the sacha has been fully exploited due dark brown colour properties associated pigments. Thus, de-colourization shells before extraction using solvents could means bring about lighter colour, which applied...

In this paper the microbubble technology was employed to increase the mass transfer rate of ozone as well as to enhance the ozone oxidation. Experiments were performed using the microbubbles generator and the bubble contactor, which is commonly used in ozonation system, for the purpose of comparison. The microbubble generator produced a milky and high intensity microbubble solution in which the...

The methanolic extract of Musa ABB cv Pisang Awak was investigated for the polyphenolic contents and antioxidant activity. The total phenol and flavonoid contents of the fruit extract were found to be 120 mg gallic acid equivalents (GAE) and 440 mg quercetin equivalents (QE)/100 g of sample dry weight, respectively. The antioxidant activity of the Pisang Awak methanol extract (PAME) (20-500 mic...

Polyamide matrices, such as membranes, gels and non-wovens, have been applied as supports for enzyme immobilization, although in literature he enzyme immobilization on woven nylon matrices is rarely reported. In this work, a protocol for a Trametes hirsuta laccase immobilization sing woven polyamide 6,6 (nylon) was developed. A 24 full factorial design was used to study the influence of pH, spa...

Textile industry is considered as one of the important factors of the economic growth in Tunisia. However, this prominent role has certainly some drawbacks mainly represented by the huge amounts of textile wastewaters generated that become a real menace to nature. Many previous studies showed the purifying potential of some activated sludge and bacteria (Pseudomonas putida) to decolourize texti...
