The world fisheries and aquaculture supplied about 142 million tons of fish in 2008, of which 115 million tons was used as human food, providing around 17 kg (live weight equivalent) per capita/per person. Aquaculture accounted for 46% of total food fish supply, a slightly lower proportion with respect to that reported in the past. Huge amount of fish and other marine organisms were eliminated ...

Immobilized Candida tropicalis cells in freeze dried calcium alginate beads were used for production of xylitol from lignocellulosic waste like corn cob hydrolysate without any detoxification and sterilization of media. Media components for xylitol fermentation were screened by statistical methods. Urea, KH2PO4 and initial pH were identified as significant variables by Plackett-Burman (PB) desi...

A recent trend in sustainable bioethanol production is the use of agricultural waste or food as an inexpensive and most available feedstock. Bread major that could be successfully used for bioethanol. The aim this study was to optimize ethanol by response surface methodology (RSM) using bread hydrolysate. Waste hydrolysate obtained crude hydrolytic enzymes produce bacterial isolate Hymenobacter...

the study was conducted at haramaya university poultry farm to evaluate the effects of locally processed fish waste meal (fwm) in the diet of white leghorn layers on the performance and hatchability, egg quality, sensory flavor and profitability of the rations. one hundred eighty chickens at five months of age were randomly distributed (15 layers per each 12 pens). the pens were randomly assign...

A method was devised to construct stable and steep chemical gradients in slide cultures to study the movements of gliding cells. The movement of Myxococcus xanthus individual cells and small swarms was studied in these gradients. There was no response to gradients of Casitone and yeast extract that were previously reported to stimulate a positive chemotactic response with M. xanthus.

Actinopyga lecanora, a type of sea cucumber commonly known as stone fish with relatively high protein content, was explored as raw material for bioactive peptides production. Six proteolytic enzymes, namely alcalase, papain, pepsin, trypsin, bromelain and flavourzyme were used to hydrolyze A. lecanora at different times and their respective degrees of hydrolysis (DH) were calculated. Subsequent...

With the development of marine biorefinery concept, utilisation algal waste during industrial processing as well some “green tide” biomass has become an important research topic. In this work, a single-step microwave process was used to hydrolyse Laminaria japonica (LJW) and Enteromorpha prolifera (EP), producing growth medium suitable for microbial cultivation. The contained range mono- polysa...

An experiment was conducted to analytically define several novel fish substrates and determine the effects of feeding diets containing these substrates on total tract nutrient digestibilities and on immune status of senior dogs. The control diet contained poultry by-product meal while test diets contained 20% milt meal (MM), pink salmon hydrolysate (PSH) and white fish meal (WFM) added at the e...

Biodegradable waste is by definition degraded by other living organisms. Every day, meat industry produces large amounts of a specific type of biodegradable waste called slaughterhouse waste. Traditionally in Europe, this waste is recycled in rendering plants which produce meat and bone meal and fat. However, feeding animals with meat and bone meal has been banned since the outbreaks of bovine ...

Summa y and Cmlusions The losses of nutrients in the cooking and plate waste of milk, eggs, fish and meat and the losses in the storage and preparation of vegctables have been studied. Records are presented also of waste in school and other canteens. Scrambling is the most wasteful method of cooking eggs. Thermostatically controlled panv would reduce the waste in cooking eggs. The filleting of ...
