Members of the genus Trichoderma are a well-established and studied group fungi, mainly due to their efficient protein production capabilities biocontrol activities. Despite immense interest in use different members this species as biopesticides biofertilizers, study active metabolites biosynthetic gene clusters has not gained significant attention until recently. Here we review challenges opportunities exploiting full potential spp. for natural products new metabolic engineering strategies used overcome some these challenges.

Abstract Efficient saccharification of lignocellulosic biomass requires concerted development a pretreatment method, an enzyme cocktail and enzymatic process, all which are adapted to the feedstock. Recent years have shown great progress in most aspects overall process. In particular, increased insights into contributions wide variety cellulolytic hemicellulolytic enzymes improved processing step brought down costs. Here, we review major technologies different process setups present in-depth discussion various types that currently use. We pay ample attention role recently discovered lytic polysaccharide monooxygenases (LPMOs), led renewed interest redox systems lignocellulose processing. Better understanding interplay between types, as they may occur commercial cocktail, is likely key further improvements.

Abstract Biorefineries, designed for the production of lignocellulose-based chemicals and fuels, are receiving increasing attention from public, governments, industries. A major obstacle biorefineries to advance commercial scale is high cost enzymes required derive fermentable sugars feedstock used. As summarized in this review, techno-economic studies suggest co-localization integration enzyme manufacturing with cellulosic biorefinery as most promising alternative alleviate problem. Thus, cultivation Trichoderma reesei , principal producer lignocellulolytic enzymes, on lignocellulosic biomass processed on-site can reduce manufacturing. Further, due a complex gene regulation machinery, fungus adjust expression towards characteristics feedstock, hydrolytic efficiency produced cocktail. Despite extensive research over decades, underlying regulatory mechanisms not fully elucidated. One aspect that has received relatively little literature influence substrate, i.e., its chemical physical composition, mixture. Considering dependent efficient enzymatic degradation lignocellulose continuous supply carbon energy, relationship between secretome composition be expected. The aim review was systematically collect, appraise, aggregate data integrate results analyzing by T. insoluble model substrates biomass. show there direct effect substrate’s complexity (rated structure, lignin–carbohydrate complex, recalcitrance saccharification) titers specific activities secretome. It further shows process-related factors, such substrate loading set-up, targets yields. transcriptome supports proposed substrate-related factors enzymes. This provides insights into interrelation which may help integrated substrate-specific cocktails at scale.

The filamentous fungus Trichoderma reesei is a prolific producer of plant cell wall degrading enzymes, which are regulated in response to diverse environmental signals for optimal adaptation, but also produces wide array secondary metabolites. Available carbon source and light the strongest cues currently known impact secreted enzyme levels an interplay with regulation metabolism became increasingly obvious recent years. While cellulase already be modulated by different mitogen activated protein kinase (MAPK) pathways, relevance signal, transmitted this pathway other fungi as well, still unknown T. interconnections chemical communication under mating conditions. Here we show that MAPkinases differentially influence darkness Hog1 homologue TMK3, not TMK1 or TMK2 required chemotropic glucose reesei. Additionally, regulate production specific metabolites including trichodimerol bisorbibutenolid, bioactive compound cytostatic effect on cancer cells deterrent larvae, conditions facilitating mating, reflects defect communication. Strains lacking either become female sterile, indicating conservation role sexual fertility In summary, our findings substantiate previously detected interconnection well involvement dependent gene metabolite genes fungi.

Organisms have developed different features to capture or sense sunlight. Vertebrates evolved specialized organs (eyes) which contain a variety of photosensor cells that help them see the light aid orientation. Opsins are major photoreceptors found in vertebrate eye. Fungi, with more than five million estimated members, represent an important clade living organisms functions for sustainability life on our planet. Light signalling regulates range developmental and metabolic processes including asexual sporulation, sexual fruit body formation, pigment carotenoid production even secondary metabolites. Fungi adopted three groups photoreceptors: (I) blue receptors, White Collars, vivid, cryptochromes, F proteins DNA photolyases, (II) red sensors, phytochromes (III) green sensors microbial rhodopsins. Most mechanistic data were elucidated roles Collar Complex (WCC) fungal kingdom. The WCC acts as both photoreceptor transcription factor by binding target genes, whereas phytochrome initiates cascade using mitogen-activated protein kinases elicit its cellular responses. Although mechanism photoreception has been studied great detail, not compared vision. Therefore, this review will mainly focus findings derived from two model organisms, namely Aspergillus nidulans Neurospora crassa comparison some mechanisms Our be way is translated into changes gene expression, influences morphogenesis metabolism fungi.
