“…However, concerns were raised for the use of miscanthus, as the liquid waste after washing of miscanthus showed an inhibitory effect on the growth of seedlings (Winzer, University of Bonn, Germany, personal communication). Furthermore, an antimicrobial effect on Pseudomonas strains and Clostridium beijerinckii was detected [ 44 , 45 ].…”

BackgroundPretreated lignocellulosic biomass is considered as a suitable feedstock for the sustainable production of chemicals. However, the recalcitrant nature of cellulose often results in very cost-intensive overall production processes. A promising concept to reduce the costs is consolidated bioprocessing, which integrates in a single step cellulase production, cellulose hydrolysis, and fermentative conversion of produced sugars into a valuable product. This approach, however, requires assessing the digestibility of the applied celluloses and, thus, the released sugar amount during the fermentation. Since the released sugars are completely taken up by Trichoderma reesei Rut-C30 and the sugar consumption is stoichiometrically coupled to oxygen uptake, the respiration activity was measured to evaluate the digestibility of cellulose.ResultsThe method was successfully tested on commercial cellulosic substrates identifying a correlation between the respiration activity and the crystallinity of the substrate. Pulse experiments with cellulose and cellulases suggested that the respiration activity of T. reesei on cellulose can be divided into two distinct phases, one limited by enzyme activity and one by cellulose-binding-sites. The impact of known (cellobiose, sophorose, urea, tween 80, peptone) and new (miscanthus steepwater) compounds enhancing cellulase production was evaluated. Furthermore, the influence of two different pretreatment methods, the OrganoCat and OrganoSolv process, on the digestibility of beech wood saw dust was tested.ConclusionsThe introduced method allows an online evaluation of cellulose digestibility in complex and non-complex cultivation media. As the measurements are performed under fermentation conditions, it is a valuable tool to test different types of cellulose for consolidated bioprocessing applications. Furthermore, the method can be applied to identify new compounds, which influence cellulase production.Electronic supplementary materialThe online version of this article (doi:10.1186/s12934-016-0567-7) contains supplementary material, which is available to authorized users.

“…Some beneficial Bacillus species have been used in the disease management of Agaricus bisporus ( Stanojevic et al, 2019 ). In some cases, sanitation with waterlogging reduces Trichoderma inocula in mushroom cultivation ( Bruno et al, 2015 ; Tong et al, 2020 ). The high diversity of Trichoderma and their rapid population growth in GL mushrooms suggest a further evaluation to control individual species.…”

Ganoderma lucidum (GL) is a well-known medicinal mushroom that has been extensively cultivated. Our previous study has shown that abundant Trichoderma colonies grow on the casing soil surface, posing cultivation obstacles for GL. However, an understanding of species-level characteristics of Trichoderma strains and their adverse effects on GL growth is limited. This study aimed to investigate the diversity and potential effects of Trichoderma from GL-cultivated soils. Over 700 Trichoderma isolates were collected from two trails in Longquan Country, southeast China. Eight Trichoderma species, including T. atrioviride, T. guizhouense, T. hamatum, T. harzianum, T. koningiopsis, T. pleuroticola, T. sp. irale, and T. virens, were identified based on the combination alignment of tef-1α and rpb2 sequences. The number of Trichoderma colonies increased dramatically during GL cultivation, with an increase of 9.2-fold in the Lanju trail. T. virens accounted for the most colonies (33.33 and 32.50% in Lanju and Chengbei, respectively) at the end of GL cultivation. The Trichoderma species growth varied but was satisfactory under different temperature or pH conditions. Moreover, Trichoderma species showed different adverse effects on GL growth. The non-volatile metabolites from T. virens and volatile metabolites from T. atroviride displayed the strongest antagonistic activity. Furthermore, the volatile 6-pentyl-2H-pyran-2-one (6-PP) showed a significant inhibitory effect on GL growth with an 8.79 μl mL−1 headspace of 50% effective concentration. The different Trichoderma spp. produced different amounts of 6-PP. The most efficient 6-PP producer was T. atroviride. To the best of our knowledge, this study is the first to demonstrate the abundance of competitive Trichoderma species associated with GL cultivation. Our results would contribute to.

“…13). The SELWs that have been obtained from pre-treatment of wheat straw, giant reed and miscanthus have been directly tested for their antimicrobial properties (Table 2) as fungicide against plant pathogenic fungi (De Corato et al, 2014), as nematocide against plant parasitic nematodes (Crow and Luc, 2014) and as bactericide towards mushroom pathogenic bacteria (Bruno et al, 2015). As aforementioned, SELWs have also been used in increasing suppressive properties of three green composts sourced from a feedstock of agro-energy co-products and agricultural wastes (De Corato et al, 2016).…”

Market implementation of integrated biorefinery requires reliable and advanced processing units combined with ecofriendly and economically profitable production chains. Future developments of the biorefinery systems should include either crop cultivation with selected genotypes that maximize full chain performance either the use of marketable agricultural residual biomass and agro-waste. The aim of the present work was to review the main biorefining opportunities of disposable agricultural residues, agricultural co/by-products and agro-wastes into a broad range of green chemicals and high-value added co/by-products valuable in some emerging technological sectors. The current status and future perspectives of conversion starting from agricultural residual biomasses and agro-wastes into highvalue co/by-products, green chemicals and energy recovery by an approach of integrated biorefinery has been considered. After a recognition on nature, origin and European classification of the main categories of organic residuals from crops, forestry, agro-industrial food processing, aquaculture, fisheries and agro-wastes, this paper has focused its challenge on the main biofuel co/by-products associated to the thermochemical and biological conversion processes.The high-value added co/by-products from the biofuel chains related to some chemical basic-platforms (e.g., succinic acid, cellulose, lignin, glycerin, etc.) have been presented and discussed. Then, a special attention towards potential U. De Corato et al. / Renewable and Sustainable Energy Review 2 applications of the high-value added co/by-products and green chemicals in three emerging fields (renewable and sustainable farming systems, bioplastic industry and cell and tissue engineering in biomedical applications) for actual and future players has been given and discuss. Finally, this paper has addressed own concern on the actual and potential biorefining opportunities in the EU and in Italy.
