In order to add value to potato peels and also curb their environmental pollution problems, this study investigated the protein enrichment of potato peels with Saccharomyces cerevisiae via Solid-State Fermentation (SSF). SSF is a fermentation process which involves solid matrix and is carried out in absence or near absence of free water. SSF of potato peel mashed was carried out with S. cerevisiae at 30°C, pH of 5.5, moisture adjustment between 40 and 90%, addition of ammonium sulphate and urea salts as nitrogen supplements for the microorganisms for 3 days. The results showed that the percentage crude protein content of all the fermented samples increased significantly when compared with the unfermented sample. 40% moisture content adjustment and ammonium sulphate as nitrogen source gave the best result. The crude protein increased from 12.5% to 21.86%, which is 74.88% increment for ammonium sulphate supplementation, and 12.5% to 18.42%, which is 47% increment for urea supplementation. Therefore, the fermented peels could serve as good source of cheap protein enriched feed for livestock. 展开更多

Background:Algae are widely recognized for their high oil content and for exponentially accumulating biomass with particular potential to provide single cell protein for human consumption or animal feed.It is believed that along with biodiesel from algae,the high protein de-oiled algal residue may become an alternative feed supplement option in the future.This study was conducted to investigate de-oiled algal residue obtained from the common Chlorella species,Thalassiosira weissflogii,Selenarstrum capricornutum,Scenedesmus sp.,and Scenedesmus dimorphus for assessment as potential feed supplements for ruminants by comparing with soybean(Glycine max) meal and alfalfa(Medicago sativa) hay.Results:With the exception of T.weissflogii,algal residue had higher concentrations of Cu,Zn,and Mn and lower concentration of Ca,Mg,and K than soybean meal and alfalfa hay.The algal residue CP(crude protein)concentrations ranged from 140 to 445 g/kg DM and varied among the de-oiled residues.In vitro rumen fermentation gas accumulation curves indicated that algal biomass degradation potential was less than that of soybean meal or alfalfa hay by up to 41.7%.The gas production curve,interpreted with a dual pool logistic model,confirmed that the fraction sizes for fast fermenting and slow fermenting of de-oiled algal residues were smaller than those in soybean meal and alfalfa hay,and the fermenting rate of the fractions was also low.Conclusions:Inferior in vitro rumen gas accumulation from the five de-oiled algal residues suggests that these algal byproducts are less degradable in the rumen. 展开更多

The effect of different extraction and purification conditions on the microbial protein obtained from solid-state fermentation(SSF)and the effect of periodical dynamic changes of air on protein have been studied.The mechanism of solid-state fermentation with periodical dynamic changes of air is also discussed.Compared with static solid-state fermentation,periodical dynamic changes of air afford a higher protein mass;from 1 g of the fermentation microbe,5.3 mg of the intracellular protein(an increase of 34.63%)and 9.09 mg of the extracellular protein(an increase of 17.8%)were obtained on the sixth day of fermentation.The filter paper activity and carboxymethyl cellulose activity(FPA and CMCase)of the extracellular protein are 1.739μmol/s and 109.592μmol/s,respectively,which represent increases of 60.1%and 21.2%over the corresponding values for static solid-state fermentation.The FPA and CMCase of the intra-cellular protein are 0.245μmol/s and 6.392μmol/s,respec-tively,which represent decreases of 22.2%and 38.7%over the corresponding values for static solid-state fermentation.The enzyme activity of the microbial extracellular protein in solid-state fermentation with periodical dynamic changes of air on the fifth day is nearly equal to that on the sixth day without periodical dynamic changes of air,so the period of fermentation can be shortened.The sodium dodecyl sulfate-polyacrylamide gel electrophoresis(SDS-PAGE)experiments suggest that pulsating air pressure stimulation leads to a decrease in the amount of protein component with molecule mass of about 80400Da,and an increase in the amount of protein component with molecule mass of about 28520Da. 展开更多

Animal nutritionists have incessantly worked towards providing livestock with high-quality plant protein feed resources.Soybean meal(SBM)has been an essential and predominantly adopted vegetable protein source in livestock feeding for a long time;however,several SBM antinutrients could potentially impair the animal's performance and growth,limiting its use.Several processing methods have been employed to remove SBM antinutrients,including fermentation with fungal or bacterial microorganisms.According to the literature,fermentation,a traditional food processing method,could improve SBM's nutritional and functional properties,making it more suitable and beneficial to livestock.The current interest in health-promoting functional feed,which can enhance the growth of animals,improve their immune system,and promote physiological benefits more than conventional feed,coupled with the ban on the use of antimicrobial growth promoters,has caused a renewed interest in the use of fermented SBM(FSBM)in livestock diets.This review details the mechanism of SBM fermentation and its impacts on animal health and discusses the recent trend in the application and emerging advantages to livestock while shedding light on the research gap that needs to be critically addressed in future studies.FSBM appears to be a multifunctional high-quality plant protein source for animals.Besides removing soybean antinutrients,beneficial bioactive peptides and digestive enzymes are produced during fermentation,providing probiotics,antioxidants,and immunomodulatory effects.Critical aspects regarding FSBM feeding to animals remain uncharted,such as the duration of fermentation,the influence of feeding on digestive tissue development,choice of microbial strain,and possible environmental impact. 展开更多

Protein sources are the second most important component in poultry diets.Due to the fluctuation in price of soybean meal(SBM) and persistent increase in feed prices,nutritionists have been exploring alternative protein sources.Replacement of SBM with alternative protein sources in poultry diets could reduce human-live stock competition for soybean and support the production of more animal protein.However,the use of alternative protein sources is limited to low inclusion due to the presence of antinutritional factors(ANF) such as glucosinolates(rapeseed meal),gossypol(cottonseed meal),nonstarch polysaccharides(NSP) in lupin flour,high fibre(palm kernel cake),total phenolic contents and phytic acid(canola meal) known to impair animal performance,nutrient digestibility and feed utilization.As a processing technique,solid-state fermentation(SSF) has been researched for a long time in the food industry.An important objective of SSF is the production of enzymes,organic acids and other metabolites of economic importance.In recent times,SSF has been employed to enhance nutrient bioavailability,inhibit gut pathogenic bacteria and reduce ANF in plant protein sources resulting in improved nutrient digestibility,thereby improving performance and gut health of broiler chickens.Unlike pigs,there is still a dearth of information on feeding solid-state fermented feed ingredients to broiler chickens.This review aims to describe the nutritional value of the solid-state fermented products of rapeseed meal,canola meal,cottonseed meal,palm kernel cake and lupin flour on performance and intestinal health of broiler chickens. 展开更多

With sustainable development of biotechnology,increasing attention has been placed on utilization of solid-state fermented feed(SFF).Solid-state fermented feed has been a candidate strategy to alleviate the contradiction between supply and demand of feed resources,ensure food hygiene safety,promoting energy conservation,and emission reduction.In production of SFF,a variety of organic acids,enzymes,vitamins,peptides,and other unknown growth factors are produced,which could affect performance of animals.Solid-state fermented feed produced by different fermentation techniques has great instability on different physiological stages of different animals,which hinders the application and standardized production of SFF.Herein,we summarize the current advances in the role of the characteristics of SFF prepared by different manufacturing technique and its research progress in animal experiments on growth performance,gastrointestinal ecology,and immune system,so as to provide references for further acquiring a relatively perfect set of SFF production and evaluation systems. 展开更多
