Improvement of protein content and decrease of anti-nutritional factors in olive cake by solid-state fermentation: A way to valorize this industrial by-product in animal feed

Publication date: Available online 16 May 2019Source: Journal of Bioscience and BioengineeringAuthor(s): Salima Chebaibi, Mathilde Leriche Grandchamp, Grégoire Burgé, Tiphaine Clément, Florent Allais, Fatiha LaziriThe present work investigates the bioconversion of the olive cake (OC) generated by olive oil industries in Morocco through solid-state fermentation using selected filamentous fungi to increase its nutritional values for subsequent valorization as ruminants feed. The fungi, namely Beauveria bassiana, Fusarium flocciferum, Rhizodiscina cf. lignyota, and Aspergillus niger were cultured on OC for 15 days. Chemical composition as well as enzymes activities were determined. Results showed (i) an increase in protein content of up to 94% for treated OC and (ii) significant (P

Conclusions A serum Aspergillus-specific IgG test is a valuable tool for the serologic diagnosis of CPA and SAIA, while an Aspergillus-specific IgM test is only modestly specific for the diagnosis of SAIA. Overall, the Aspergillus-specific IgG test is more valuable compared to IgM for the treatment duration monitoring.

Controlling aflatoxigenic Aspergillus flavus (Af) and aflatoxins in grains and food during storage are great challenge to humans worldwide. Alcaligenes faecalis N1-4 isolated from tea rhizosphere soil can produce abundant antifungal volatiles, and greatly inhibited the growth of Af in un-contacted face-to-face dual culture tests. Gas chromatography tandem mass spectrometry revealed that dimethyl disulfide (DMDS) and methyl isovalerate (MI) were two abundant compounds in the volatile profiles of N1-4. DMDS with the highest relative abundance (69.90%, to the total peak area) in N1-4 volatiles eventually prevented the conidia...

AbstractThe authors report a case ofAspergillus aortitis and aortic valve endocarditis that developed after coronary artery bypass surgery resulting in recurrent, embolic, bilateral lower extremity ischemia. This necessitated multiple lower extremity embolectomies followed by redo ‐sternotomy, extensive annular debridement, root reconstruction with a modified Bentall technique, and hemiarch replacement. This case highlights the challenges in diagnosis and management of this rare disease entity and some of its devastating complications.

In this study, chemically pretreated SB was mixed with dry spent yeast (DSY) at a mass ratio of 60:40 before being fermented under solid-state fermentation (SSF) by Aspergillus niger TK1. The fermented solids at a concentration of 24 g/L (on a dry basis) was subsequently hydrolyzed to produce a hydrolysate, which was concentrated to contain 29.7 ± 0.6 g/L of reducing sugar and 585.1 ± 6.5 mg/L of free amino nitrogen. The concentrated hydrolysate was fermented by Saccharomyces cerevisiae TISTR 5339, yielding 8.98 ± 0.2 g/L of ethanol....

Biomass by-product of beer production is constituted by viable and non-viable flocculated yeasts which are discarded. To increase the value of this waste, the potential applications of the beer fermentation residue (BFR) as probiotic and bio-preservative were studied. Strains isolated from commercial brewing starters and BFRs were...

This study examines changes in phenolic compounds and the antioxidant activity of Mexican mango seed in the bioprocess of solid-state fermentation (SSF) with the fungus Aspergillus niger GH1. The chemical composition and evaluation of mango seed as solid fermentation substrate support was also evaluated. Because of the chemical composition and the rapid growth of the fungus, mango seed is a suitable material to be used in SSF. The results showed that SSF of mango seed mobilized the polyphenolic compounds and improved the nutraceutical properties. The total phenol content in ethanol extract increased (p
