Protein enhancement of sugar beet pulp by fermentation and estimation of protein degradability in the rumen of sheep

Mediterranean agro‐industrial wastes as valuable substrates for lignocellulolytic enzymes and protein production by solid‐state fermentation

“…All fungi increased the protein content; however, A. ibericus MUM 03.49 showed the maximum increase in each waste studied. The fungal biomass protein is considered a good source of dietary protein for the feeding of ruminants and improves animal performance . In the same way, the fungal biomass protein was successfully tested in fish diets…”

“…On the other hand, lignocellulosic wastes are considered as being of low digestibility, but SSF by fungi can improve the digestibility by enzymes production, since these can break the bonds of hemicellulose and cellulose with the lignin. In addition, the SSF of lignocellulosic materials can increase the degradability of dietary protein in the rumen . Thus, several nutritional aspects of agro‐food wastes can be improved in the same biotechnology process, increasing the value of wastes.…”

Kandungan Fraksi Serat Pelepah Sawit Hasil Biodelignifikasi Menggunakan Kapang Phanerochaete chrysosporium dengan Penambahan Mineral Ca dan Mn

“…Semakin tinggi kandungan hemiselulosa maka akan semakin banyak sumber energi yang mudah dimanfaatkan oleh mikroba rumen, hal ini disebabkan hemiselulosa merupakan struktur karbohidrat kompleks yang tersusun atas polimer pentosa (xylosa, arabinosa), heksosa (mannosa, glukosa, galaktosa) dan asam gula (Church dan Ponds, 1982;Dashtban et al, 2009;Hendriks dan Zeeman, 2009); hemiselulosa mempunyai berat molekul lebih kecil dibandingkan selulosa dengan cabang rantai pendek terdiri dari gula berbeda (Perez et al, 2002) sehingga lebih mudah dihidrolisis (Hendriks dan Zeeman, 2009). Hidrolisis hemiselulosa dapat dilakukan oleh beberapa mikroorganisme yang mampu menggunakan gula sebagai substratnya sehingga terjadi pemecahan hemiselulosa pada tahap awal fermentasi dan bakteri asam laktat akan merombak hemiselulosa setelah karbohidrat habis terpakai dan membentuk asam organik (McDonald, 2010 lulosa 55% pada fermentasi pulp produk samping gula beet menggunakan kapang T. reesei (Iconomou et al, 1998). Kandungan selulosa pada dinding sel tanaman berkisar 35% (Lynd et al, 2002) sampai 45% (Perez et al, 2002) dari berat kering tanaman.…”

Bio-processing of agro-byproducts to animal feed

“…Generally, agro-byproducts have low protein content (2-6%) and fungal growth can improves it to 10-15% (Shojaosadati et al, 1999). However, the degradability of dietary protein in the rumen from fermented lignocellulosic byproduct was higher compared with unfermented byproducts (Iconomou et al, 1998). Besides protein, an increase of total lipid and fatty acids was observed after solid-state fungal fermentation of agricultural residues (Abu et al, 2000).…”
