“…It is unlikely to determine the kinetic profiles of the reducing sugar generation and consumption during the SSF system, as the sugars can be consumed simultaneously by the fungal cell growth, enzyme generation, and metabolic production. The residual sugars can be generated by the biochemical reactions induced by the fungal cell growth, while being consumed by the metabolic reactions during the course of fermentation (Karpe et al, 2015a). Thus, the overall residual sugars measured from the SSF tests were the difference between the generation and consumption of the total sugars.…”

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.

“…There are a few of recent studies which were conducted to use fungi for degrading hemicellulose biomass from winery (Karpe et al, 2015a(Karpe et al, , 2015b. There is a need to develop a technology for conversion of winery wastes to value-added products, leading to sustainable waste management strategy.…”

“…Of note, each sample site was collected in triplicate and then subsequently analyzed in triplicate. All samples were derivatized prior to analyses by gas chromatography-mass spectrometry (GC-MS) as mentioned in previous studies [43,44,45]. Briefly, a 1.0 mL aliquot of ice cold methanol (LC grade, ScharLab, Sentemanat, Spain) and MilliQ water (50:50 v/v ) were added to each sample pellet, then vortexed briefly before centrifugation at 572.5 g for 15 minutes at 4 °C.…”

A multi-omics approach was applied to an urban river system (the Brisbane River (BR), Queensland, Australia) in order to investigate surface water quality and characterize the bacterial population with respect to water contaminants. To do this, bacterial metagenomic amplicon-sequencing using Illumina next-generation sequencing (NGS) of the V5–V6 hypervariable regions of the 16S rRNA gene and untargeted community metabolomics using gas chromatography coupled with mass spectrometry (GC-MS) were utilized. The multi-omics data, in combination with fecal indicator bacteria (FIB) counts, trace metal concentrations (by inductively coupled plasma mass spectrometry (ICP-MS)) and in-situ water quality measurements collected from various locations along the BR were then used to assess the health of the river ecosystem. Sites sampled represented the transition from less affected (upstream) to polluted (downstream) environments along the BR. Chemometric analysis of the combined datasets indicated a clear separation between the sampled environments. Burkholderiales and Cyanobacteria were common key factors for differentiation of pristine waters. Increased sugar alcohol and short-chain fatty acid production was observed by Actinomycetales and Rhodospirillaceae that are known to form biofilms in urban polluted and brackish waters. Results from this study indicate that a multi-omics approach enables a deep understanding of the health of an aquatic ecosystem, providing insight into the bacterial diversity present and the metabolic output of the population when exposed to environmental contaminants.

Tannins are secondary metabolites widely distributed in the plant kingdom. They act as growth inhibitors towards many microorganisms: upon microbial attack, they are released helping to fight the infection of plant tissues. Extraction of tannins from plants is an active industrial sector with several applications from the beginning of the industrial era. Actually, tannins have many industrial applications in oenology, animal feeding, mining and chemical industry and, in particular, in the tanning industry. But tannins are also considered very recalcitrant pollutants in wastewaters of different origins. The ability to grow on plant substrates rich in tannins and on industrial tannin preparations is traditionally considered peculiar of some species of fungi that have developed mechanisms to tolerate the toxicity of tannins producing a complex enzymatic pattern active in the transformation of these substrates, mainly by hydrolysis and oxidation. Filamentous fungi capable of degrading tannins could have a strong environmental impact as bioremediation agents mostly in the treatment of tanning wastewaters.
