“…At the present time, several SMs have been reported, and these are the main groups found in Trichoderma isolates: polyketides, peptaibols, terpenoids/steroids; pyrones and daucanes (Zeilinger et al 2016). The SMs may play an antibiotic function against plant pathogens (Daoubi et al 2009, Takhiro et al 2013), act as a plant growth regulator, and have pharmacological properties for use as antiaging agents, cholesterol lowering agents, cancer cell fighters, immunological suppressors (Keswani et al 2014) and flavoring for the food industry (Fadel et al 2015).…”

Antifungal potential of crude extracts of Trichoderma spp.

Antibiosis is the mechanism by which certain microorganisms respond to the presence of others, secreting compounds or metabolites capable of inhibiting or impeding their development. The crude extract of Trichoderma contains a mixture of secondary compounds, which may show antibiotic effect, and has been used for the prospect of this fungus for biological control and other industrial purposes. Faced with the increasing demand of agriculture for ecologically compatible alternatives for the management of diseases, this work aimed to investigate the spectrum of action of NonVolatile Metabolites (NVMs) of Trichoderma isolates against different plant pathogenic fungi. The antagonistic potential of NVMs was evaluated through the incorporation method of the filtered liquid extract in PDA medium. The assays showed that all the NVMs produced inhibited the fungus Sclerotinia sclerotiorum similarly. On the other hand, strains CEN1245 and CEN1274, both belonging to the species Trichoderma brevicompactum, showed broad spectrum against Sclerotium rolfsii, Colletotrichum gloesporioides, Verticillium dahliae, Fusarium oxysporum and Cylindrocladium sp. The present study describes isolates producing non-volatile metabolites with broad spectrum of antifungal action, as well as pathogen-specific. The Trichoderma spp. NVMs obtained from different soil samples cultivated with vegetables, cassava and maize were efficient in inhibiting plant pathogenic fungi belonging to other patossystems, such as forest or fruit, which could increase their potential application in biological control of plant diseases. In addition, these antagonistic fungi should be studied in greater depth for the identification of bioactive molecules of industrial interest or in commercial formulations of products for biological control of plant pathogens.Keywords: secondary metabolites, antagonism, inhibition of mycelial growth, plant pathogenic fungi.

“…Aromatic compounds were also expected to be indigenous resulted by SSF of Trichoderma viridae in Pandanus tectorius fruits since it showed difference aromatic compounds compositions obtained by SSF of Trichoderma viridae and Trichoderma harzianum grown in sugarcane bagasse (5,6,7,8). Therefore we concluded that aromatic compounds were potentially produced by SSF of Trichoderma viridae in Pandanus tectorius fruits.…”

“…We compared the nutritional composition between Pandanus tectorius fruit and sugarcane bagasse which were previously reported as potential substrates for aromatic compounds production by SSF of Trichoderma viridae and Trichoderma harzianum [5][6][7][8] . Compared to sugarcane bagasse, total sugars content in Pandanus tectorius fruits were found lower than sugarcane bagasse, while protein and moisture content of the substrates were higher than sugarcane bagasse.…”

Production of microbial aromatic compounds by solid-state fermentation is increasing lately, due to the ability of microbial to use agro-industrial wastes as their substrates. The aim of this research was to know potential of aromatic compounds production by solid-state fermentation of Trichoderma viridae in Pandanus tectorius fruits. To prepare the substrates, basal mesocarp part of fruits were cut, juiced, pulps were dried and grinded until reached fine particle size. Fermentations were carried out in 250 mL flasks with 10 8 fungal spores/mL, pH 6.0, 76,6 % (w/v) moistures at 30°C for 10 days. Aromatic compounds resulted from SSF were then analyzed using GC/MS. Results showed that Pandanus tectorius fruits contained total sugars 13,015%, proteins 3%, lipids 1,39% and moisture content were 76,6%. This low sugars content in substrates seemed to be the main factor of Trichoderma viridae slow growth. There were 17 peaks of aromatic compounds detected in GC/MS, consisted of alkenes hydrocarbons (tetradecane, tertracosane, tetracosahexaene, pentadecane, hexacosane, heptadecane, and octadecane), alcohol (phenol), amide (9-octacenamide) and monoterpene aldehid (9-octadecenal). Therefore the fermentation conditions need to be further optimized to make better growth for fungi and higher aromatic compounds production.

Abstract:The establishment of a bioeconomy era requires not only a change of production pattern, but also a deep modernization of the production processes through the implementation of novel methodologies in current industrial units, where waste materials and byproducts can be utilized as starting materials in the production of commodities such as biofuels and other high added value chemicals. The utilization of renewable raw resources and residues from the agro-industries, and their exploitation through various uses and applications through technologies, particularly solid-state fermentation (SSF), are the main focus of this review. The advocacy for biocatalysis in green chemistry and the environmental benefits of bioproduction are very clear, although this kind of industrial process is still an exception and not the rule. Potential and industrial products, such as biocatalysts, animal feed, fermentation medium, biofuels (biodiesel, lignocelulose ethanol, CH 4 , and H 2 ), pharmaceuticals and chemicals are dealt with in this paper. The focus is the utilization of renewable resources and the important role of enzymatic process to support a sustainable green chemical industry.
