“…In this study, A. terreus was found to be following the correlation among protein content and cellulases as the maximum amount of proteins and cellulases were produced by it. Using Trichoderma citronoviridae, degradation of sugarcane straw was found to increase by 6.2-7.9% (Guerra et al (2006)). Margolles et al (1996) have also shown the production of endo-chitinases and cellulases using Trichoderma harzianum and Trichoderma reesei.…”

“…The reduction in cellulose content of the trash with increasing cellulases was well fitting in a linear equation with regression coefficient 0.72 (Fig 1a). Guerra et al (2006) have shown the production of cellulases by growing Trichoderma citronoviridae on solid beds of sugarcane straw, as this fungus is able to utilize sugarcane straw as a sole carbon source.…”

Pretreatment of lignocellulosic biomasses, the first step in their conversion to utilizable molecules requires very high energy (steam and electricity), corrosion resistant high-pressure reactors and high temperatures. These severe conditions not only add to the cost component of the entire process but also lead to the loss of sugars to the side reactions. Microbial pretreatments have been reported to be associated with reducing the cost factors as well as the severities of the reactions. Eight bioagents, including fungi and bacteria, were screened for their pretreatment effects on sugarcane trash. They narrowed down the C:N ratio of trash from 108:1 to a varying range of approximately 42:1 to 60:1.The maximum drop in C:N ratio of 61% was observed using Aspergillus terreus followed by Cellulomonas uda (52%) and Trichoderma reesei and Zymomonas mobilis (49%). The bioagents helped in degradation of sugarcane trash by production of cellulases, the maximum being produced by A. terreus, (12 fold) followed by C. uda (10 fold), Cellulomonas cartae (9 fold) and Bacillus macerans (8 fold). The microbial pretreatment of trash rendered the easy accessibility of sugars for enzymatic hydrolysis, which can be directed for production of alcohol.

“…Blaszczyk et al (2011) found it to be common in forest soil, wood in forests and mushroom compost in Poland. Cellulases produced by strains identified as this species have been utilized in bioconversion (Guerra et al 2006; Chandra et al 2009a, b, 2010) but the species is capable of growing and sporulating at human body temperature and thus extreme care must be taken if its conidia are to be mass-produced.…”

The Longibrachiatum Clade of Trichoderma: a revision with new species

et al. 2012

View full text Add to dashboard Cite

The Longibrachiatum Clade of Trichoderma is revised. Eight new species are described (T. aethiopicum, T. capillare, T. flagellatum, T. gillesii, T. gracile, T. pinnatum, T. saturnisporopsis, T. solani). The twenty-one species known to belong to the Longibrachiatum Clade are included in a synoptic key. Trichoderma parareesei and T. effusum are redescribed based on new collections or additional observations. Hypocrea teleomorphs are reported for T. gillesii and T. pinnatum. Previously described species are annotated.

“…Mn peroxidase and Laccase activities was found during SSF of some insoluble substrate, such as sawdust, wheat straw and bagasse (Hofrichter et al, 1999). Employ SSF of lignocelluloses materials for enzyme production provide important advantages, such as: it mimics the natural environment of the white-rot fungi, simplifying the culture media and permits low content of water to obtain concentrated crude enzymes (Guerra et al, 2006). This investigation was carried out to obtain fungal ligninolytic enzymes in solid bed supplemented with sugarcane bagasse for their use in the biotransformation of textile dyes.…”

Three strains of white-rot fungi were tested in solid state fermentation and submerged culture to obtain enzymes for dyes biotransformation. Both sugarcane bagasse and dyes induced laccase and manganese peroxidase biosynthesis but laccase seems to be the main enzyme related to the decolourisation profiles. A variable behavior of strains was observed depending on inducers, fermentation system and characteristics of the strains. Crude enzyme of Earliella scabrosa obtained in solid state fermentation showed higher decolourisation percentage of Navy FNB and Red FN-3G dyes than Trametes maxima (13) and Ganoderma zonatum (B-18). T. maxima exhibited the best decolourisation percentage in submerged cultures supplemented with Navy FNB, Red FN-3G and yellow P-6GS dyes. Growing biomass of T. maxima could supply other enzymes and mediators for dyes transformation. Peculiar behaviour was observed with Ganoderma zonatum (B-18), it had a similar dyes biodegradation in both liquid and solid bed fermentation and there was not positive correlation between ligninolytic enzymes production and decolourisation pattern. The employment of crude enzymes produced in solid bed of bagasse could be an attractive option for biological removal of textile dyes.
