Oil contamination in the soil has been a major threat to the environment because of the poor solubility. Crude oil can be accidentally or deliberately released into the environment leads to serious pollution problems (Trindale et al., 2005). Bioremediation is a waste management technique that involves the use of the organisms to remove or neutralize pollutants from a contaminated site. An alter...

Isolation of proteins from rice bran was studied, comparing alkaline- and carbohydrase-aided extraction. It was found that protein extractability could be effectively improved using carbohydrases (Viscozyme L and α-amylase), especially when mechanical force was incorporated. Then, rice bran protein hydrolysates (RBPH) were prepared at various degrees of hydrolysis (DH), and employed to stabiliz...

Functional polysaccharide was isolated from Momordica charantia, with a yield of 36% (w/w). M. charantia bioactive polysaccharide (MCBP) was an acidic and branched heteropolysaccharide with a molecular weight of 92 kDa. Fourier transform infrared spectroscopic analysis indicated that MCBP was a pectin-like polysaccharide with an esterification degree of 53% and it contains numerous monosacchari...

Many bacteria synthesize extracellular polysaccharides (EPSs) with commercially significant physiological and therapeutic activities. Microbial polysaccharides have also been reported to have potential therapeutic applications. Recently, much attention has been devoted to the microbial exopolysaccharides (EPSs) due to their numerous health beneûts.EPSs from lactic acid bacteria are reported to ...

In this study, the effects of limited hydrolysis and/or high-pressure homogenization (HPH) treatment in acid conditions on the functional properties of oyster protein isolates (OPI) were studied. Protein solubility, surface hydrophobicity, particle size distribution, zeta potential, foaming, and emulsifying properties were evaluated. The results showed that acid treatment led to the dissociatio...

This study describes the potential use of olive oil and olive oil-pomegranate juice sauces as antioxidant, preservative and flavoring agent in fish marinades. The olive oil and sauces, produced from emulsifying of olive oil and pomegranate juice with gums, were blended with marinated anchovy (Engraulis encrasicholus) fillets. The aim of the present study was to produce a new polyphenol-rich mar...

Composting of oiled bleaching earth with waste sludge and corn straw was carried out to investigate the ability of microorganisms to synthesize biosurfactants that might decrease the surface tension of composts. Analytical results and changes in the surface tension suggest that biodegradation of fatty by-products was the consequence of emulsifying properties of higher fatty acids. The surface t...

A novel sodium N-fatty acyl amino acid (SFAAA) surfactant was synthesized using pupa oil and pupa protein hydrolysates (PPH) from a waste product of the silk industry. The aliphatic acids from pupa oil were modified into N-fatty acyl chlorides by thionyl chloride (SOCl2). SFAAA was synthesized using acyl chlorides and PPH. GC-MS analysis showed fatty acids from pupa oil consist mainly of unsatu...
