Squids belong to the cephalopod family, which composes more than 5% of the total annual fishing volume of southern Iran as by- products; however, these do not have significant usage in Iran. This product was studied to extract the high-value products, i.e. marine oils rich in unsaturated multiple-band fatty acids from 50kg squid (Loligo loligo) obtained from Chabahar fishing port and transferre...

polyhydroxyalkanoates (phas) is known to be temporarily stored by microorganisms in activated sludge, especially in the anaerobic-aerobic processes. the main objective of this study was to investigate the effects of fatty acids (vfas) compounds coexistence in substrate of sbr on phas productivity of activated sludge. it has been found that addition of different concentrations of vfas results in...

Slurry ice is a biphasic system that has recently shown a number of advantages when employed as a chilling medium for fish species. Its use for a crustacean species of high commercial value -namely Norway lobster (Nephrops norvegicus)was evaluated in parallel to traditional flake icing. Quality parameters related to microbial spoilage and biochemical breakdown (aerobe and psychrotroph counts, p...

Volatile compounds produced during the processing stages of Paínho de Portalegre, a portuguese traditional dry fermented sausage, were extracted and analyzed by a purge and trap gas chromatography flame ionization detector system (PT/GC/FID). A total of fourty five volatile compounds were detected, which included aldehydes (13), ketones (12), alcohols (9), esters (2), volatile fatty acids (3), ...

This study investigated the effect of sunlight-dark conditions on volatile fatty acids (VFAs), total ammonium nitrogen (TAN), total alkalinity (TA) and pH during pig manure (PM) digestion and then the subsequent influence on biogas yield of PM. PM1 and PM2 were performed in a transparent reactor and a non-transparent reactor, respectively. Two sets of experiments were conducted with a temperatu...

This work describes a methodology for the valorization of non-food biomass production biosourced molecules via biohydrogen and metabolites fermentations such as volatile fatty acids. The commercial anion exchange resin Amberlite IRA-400(Cl) was chosen extraction carboxylic Different operating conditions were set up namely amount to be used, activation methods, pH their effects on capacity solve...
