Screening Filamentous Tropical Fungi for their Nutritional Potential as Sources of Crude Proteins, Lipids and Minerals

Abstract

The use of fungal and yeast biomass in foodstuff, either as supplements or as major ingredients in formulations is an area of growing interest for the modern food industry. The aim of this study was to evaluate the nutritional potential of biomasses obtained from filamentous fungi Penicillium sclerotiorum, Penicillium janthinellum, Rhizopus stolonifer and Syncephalastrum racemosum. Biomasses presented 26-37% of total proteins, 1.7-3.5% of lipids and 4.6-9.1% of ashes. The humidity level reached 75-83%. Ashes were screened for minerals contents with a special outcome for S. racemosum biomass that presented 3438 mg/100 g (dw) of magnesium. Fatty acids present in the biomasses were screened and the palmitic (C16:0), estearic (C18:0), elaidic (18:1n9-t), oleic (18:1n9-c), linolelaidic (C18:2n6-t), linoleic (C18:2n6-c) and γ-linolenic (C18:3n6) acids were found to be the most abundant, from a total of 88-90% of identified fatty acids. Overall data indicate that the filamentous fungi studied have good nutritional properties, possessing a combination of good level of proteins, low level of fat, and presence of essential fatty acids, including omega-3 derivatives, along with the presence of Ca, Mg, Zn and Fe.

Feeding Values of Non-Biodegraded and Biodegraded Cassava Root Sievate for Goats Using in vitro Gas Production Technique

“…The lower values reported for the CF and the fibre fractions may be due to the hydrolytic nature of the fungi species, which could have delignified the lignocelluloses complex and utilised them by microbes during fermentation thus converting them to more useful components like protein or NFE. This conforms with the report of Carvalho et al 27 that enzymes from most fungi can improve not only the non-starch polysaccharides but also the crude proteins, minerals and fatty acids. Akinfemi et al 4 , Barde et al 20 and Ochepo 21 have earlier reported improved ash values on agro by-products degraded using Pleurotus spp.…”

Evaluation of fungal single cell protein as aqua feed on carcass analysis and growth performance of Cirrhinus reba fingerlings

“…oryzae biomass produced in SSL (60%) (Asadollahzadeh et al, 2018). Carvallo et al (2010) found a much lower Ca content (4.90±0.30 and 258.40±2.28 mg/100gm) of different filamentous fungi than the present study. The contents of Zn and Fe of the present study were much higher than those found in the biomass of different filamentous fungi reported by Carvallo et al (2010).…”

“…The presence of in A. niger ‐SCP indicated that it was a good choice as a feed supplement as vitamin A is required for fish growth and development. A few studies were reported on the vitamin B complex content of fungal SCP (Adedayo et al, 2011) and filamentous fungi (Carvallo et al, 2010). To the best of the existing knowledge, for the first time, vitamin A, D 2 , D 3 and E of A. niger ‐SCP from whey were reported.…”
