“…On the other hand, some authors identified that both co-cultures and axenic cultures were unable to degrade lignin with rates of 0%. This result can be due to the absence of ligninolytic potential (Karpe et al, 2014;Cui et al, 2015), the intensive holocellulose hydrolysis by the fungi (Carvalheiro et al, 1994;Ezeonu et al, 2016) or the sterilization with temperature and pressure variation (van Heerden et al, 2008), which caused a concomitant increase in the relative lignin content.…”

The lignocellulosic biomass is a highly abundant and renewable resource. However, its exploitation is limited by the recalcitrance of the lignin present in the plant cellwall. In the last three decades, fungal co-cultures have increasingly been applied to overcome lignin recalcitrance by enhancing the production of ligninolytic enzymes through microbial interactions. In this paper, we systematically compile studies on fungal co-cultures used in the degradation of lignin-containing substrates to clarify the advantages and limitations of this type of culture. Based on their different delignification rate potentials, co-cultures can be classified into synergistic, antagonistic, and neutral. Co-cultivation results are generally related to the balance or imbalance of antagonistic and synergistic effects arising from the specific compatibility between the species during the interaction. It is well known that the paired species and the microenvironmental system conditions are responsible for the reported degradations,however, the mechanisms underlying these interactions remain poorly understood. In conclusion, literature results demonstrate the promising application of fungalco-cultures in biotechnological sectors to improve the degradation of lignin and its derivatives, through their better understanding of the efficient exploitation ofbiological resources on ecological and industrial scales.

Low‐temperature, Low‐Energy, and High‐Efficiency Pretreatment Technology for Large Wood Chips with a Redox Couple Catalyst

et al. 2018

The pretreatment of lignocellulosic biomass plays a vital role in the conversion of cellulosic biomass to bioethanol, especially for softwoods and hardwoods. Although many pretreatment technologies have been reported so far, only a few pretreatment methods can handle large woodchips directly. To improve the efficiency of pretreatment, existing technologies require the grinding of the wood into small particles, which is an energy-consuming process. Herein, for the first time, we report a simple, effective, and low-temperature (≈100 °C) process for the pretreatment of hardwood (HW) and softwood (SW) chips directly by using a catalytic system of FeCl /NaNO (FCSNRC). The pretreatment experiments were conducted systematically, and a conversion of 71.53 and 70.66 % of cellulose to sugar could be obtained for the direct use of large HW and SW chips. The new method reported here overcomes one of the critical barriers in biomass-to-biofuel conversion, and both grinding and thermal energies can be reduced significantly.

Biomass Volume Estimation and Valorization for Energy

Industrialization is a major promoter of any nation's economy; it is not without detrimental effects on our immediate environment. Human exposure to various pollutants discharged into the environment may lead to serious health challenges. In the same vein, discharge from the combustion of fossil fuel contributes a great deal to the environmental pollution. The resulting quest for a clean and sustainable environment has spurred myriads of research into advantageous utilization of waste biomass in industrial wastewater treatment and environmentally friendly/alternative energy. Similarly, diverse waste materials have been adopted as sources of important phytochemicals with different medicinal applications. This chapter focuses on the application of waste biomass in environmental remediation, curative medicine, and clean/alternative energy.
