  The antagonistic mechanism used by four Trichoderma isolates against peanut moulds; Aspergillus flavus, A. parasiticus, A. niger, A. ochraceous and Fusarium species was investigated under laboratory conditions. Two isolates of T. harzianum namely Th1 and Th2 and two isolates of T. viride, Tv1 and Tv2, were found to efficiently suppress the growth of peanut moulds and to significantly reduce aflatoxins, AFB1 and AFB2, contents in infected peanut kernels. The degree to which Trichoderma species suppressed the growth of peanut moulds correlated to their extracellular enzymatic activities. The Trichoderma isolates displayed various extracellular enzymatic activities including amylolytic, chitinolytic, pectinolytic, proteolytic, lipolytic and cellulolytic to fight off the other fungal competitors in the media. The more diverse the enzymatic activities, the more effective are the antagonists in suppressing the growth of peanut moulds and aflatoxin production in kernels. Present results suggest that Trichoderma-enzymolomic can be exploited as potential antimicrobial candidates against peanut moulds and the subsequent aflatoxin production in peanut kernels.

  The increasing demand of energy and concern of green house gas emission has resulted in searching for a renewable form of energy that is less pollutant and economically efficient. To achieve this goal, biofuel technology is now globally embraced as the promising technology to replace petroleum fuels with alternative fuels produced from renewable sources such as cellulosic biomass. In this review, we highlight the advantages and disadvantages of the petroleum fuels, been in use this far. In addition, we focus on the processes of alternative fuel production and their impacts, both positive and negative, at environmental, economical and ecological levels. The review also addresses how the available cellulosic biomass resources at our disposal can be used to positively affect the future generations.
