“…Researchers found that the supplementation of different nitrogen sources, such as NH 4 H 2 PO 4 , urea and yeast extract, showed positive effect on the fermentation performance in the bioconversion processes (Diaz et al, 2012;Hu et al, 2011). Scientists (Botella et al, 2005;Hu et al, 2011) reported that supplementation of nitrogen sources and minerals could be beneficial for the fungal growth in SSF, which agreed with the findings in this study. Diaz et al (2012) stated that the addition of a nitrogen source and minerals in SSF of grape marc can enhance the enzyme production.…”

“…2b). Botella et al (2005) stated that a low sugar concentration of 0.05 mM was found after 22 h fermentation using A. awamori and a peak of 0.14 mM was achieved after 24 h. Cauto et al (2003) reported similar results in sugar consumptions on grape seeds using yeast.…”

“…The protein-enriched grape marc, as the target product of the SSF process, must fulfill certain requirements as an alternative feedstock (Botella et al, 2005;Sanchez et al, 2002). The bioconversion product using fungi must have a high protein content and digestibility, and is safe for human or animal consumption.…”

“…As these fungi have been used in food processing and enzyme production, the fungal biomass produced by these strains can be safe for human and animal consumption (Ghorai et al, 2009;Gummadi and Panda, 2003). Botella et al (2005) stated that solid grape wastes were competitive with other agricultural wastes when they were used as a substrate in a SSF process. Sanchez et al (2002) investigated the application of grape pomace for producing animal feed using Pleurotus sp.…”

Digestibility Fungi Protein enrichmentWinery biomass waste Solid state fermentation a b s t r a c t Grape marc and lees are main waste biomass in wine industry, which contain substantial amount of carbohydrates and nutrients, but currently deliver considerable carbon emission through landfill in Australia. This study was aimed to develop a biotechnological systematic approach to select suitable fungi for bioconversion of the winery biomass wastes into animal feed. The biotech-systematic approach was developed through assessment of nutrient/carbon source accessibility of the fungi, understanding of their metabolic reactions in solid state fermentation, and nutritive value of the fungi-fermented grape marc. From 13Aspergillus, Rhizopus, and Trichoderma fungal species, A. oryzae DAR 3699, A. oryzae RIB40 and T. reesei RUT C30 were determined as the best fungi due to their promising biochemical capabilities to enhance protein contents and in vitro digestibility of grape marc in mono-and co-cultivations. The mono-fungous-cultured SSF process used these selected fungi is able to convert grape marc to nutrient-rich feed by increasing the protein contents from ∼5% to 26% and the digestibility from ∼25% to over 50%. R. oligosporus 2710 with R. oryzae 6201 or T.viride 15719 showed promising protein enrichment to 18-23% and digestibility improvement by ∼50% in their co-cultivations. This preliminary bioengineering strategy will be useful for selecting microorganisms for the bioconversion of organic wastes to high valuable products.This "green cycle" bioprocess will be useful to promote the old-fashioned waste treatment technologies for the cleaner production in food processing industries.

“…strain using a mixture of orange bagasse, wheat bran and sugarcane bagasse. However, Botella et al (2005) found the maximum exo-PG activity on the 25th hour of the fermentation with an Aspergillus awamori strain cultivated on grape pomace. The productivity of this process was calculated as: 1.43 U g substrate −1 h −1 on the 4th day of incubation.…”

a b s t r a c tWheat bran, among various agro industrial by products, screened for the production of polygalacturonase (PG) in solid-state fermentation of Aspergillus sojae mutant strain, was found to be the most suitable substrate without the addition of any nutritive or inducing supplement. It was further characterized for its physicochemical composition and particle size distribution. The process conditions that favored the PG production using this substrate were determined as; 10 7 spore/g substrate inoculum concentration, 4 days of fermentation, 37• C of incubation temperature, 62% initial moisture content, water as the moistening agent, 100-250 m particle size of wheat bran, 3 times/day agitation and spore solution as the inoculum type which resulted into maximum PG activity of 535.4 U/g substrate. Overall, this optimization process resulted in 7.3 and 3.9 fold of significant enhancement in the PG activity and productivity, respectively.
