“…Some protective compounds recently isolated from endophytes are taxol, oocydin-A, cryptocin, ambuic acid and jesterone (14)(15)(16)(17) . However, Hutchinson (18) gave direct evidence by quantitative analysis of these volatiles. (13) detected the following substances from volatile fraction of culture filtrates of fungi: acetaldehyde, n-propanol, propionaldehyde, isobutanol, n-butyraldehyde, ethyl acetate, isobutyl acetate and acetone.…”

Antagonistic potentials of seven rhizoshere soil fungi viz., Aspergillus flavus Link., A. fumigatus Fresen., A. niger Tiegh., A. terreus Thom., Penicillium sp., Trichoderma harzianum Refat. and T. viride Pers. were tested against the Fusarium oxysporum Schlecht. and F. solani (Mart.) Sacc. – the two pathogens, isolated from wilted roots of brinjal plants. Out of seven soil fungi Trichoderma harzianum was found most effective to control the growth of both the test pathogens. More than 50% inhibition of the test pathogens were observed with T. viride, Aspergillus niger and A. fumigatus in colony interaction. The maximum inhibition of radial growth of the test pathogens was observed with volatile metabolites and cell free culture filtrates of Trichoderma harzianum. This fungus may be exploited commercially to control the disease. Dhaka Univ. J. Biol. Sci. 24(2): 137-145, 2015 (July)

“…One control set comprised A. bisporus cultures paired with plates of uninocu-lated MEA, and the second set comprised A. bisporus paired with Rhizoctonia solani which was inoculated and grown on 2% MEA in the same manner as T. harzianum. R. solani was included as a control since Hutchinson and Cowan (7) found that growth of Aspergillus niger, Pestalotia rhododendri, and several bacteria in the headspace gases from cultures of a strain of T. harzianum could be accounted for solely by the presence of CO 2 and ethanol produced by the T. harzianum cultures. R. solani has a growth rate similar to T. harzianum and presumably releases similar levels of CO 2 .…”

Effect of Metabolites Produced by Trichoderma harzianum Biotypes and Agaricus bisporus on Their Respective Growth Radii in Culture

Trichoderma harzianum biotypes Th1, Th2, and Th3 produced volatile metabolites in vitro which had similar fungistatic effects on the growth of Agaricus bisporus. Metabolites present in agar colonized by these strains also inhibited mycelial growth of A. bisporus, although the reduction in growth was less in the presence of metabolites produced by biotype Th2 than that in the presence of metabolites produced by Th1 or Th3.A. bisporus produced metabolites in liquid culture that inhibited the growth of Th1 and Th3 but stimulated the growth of Th2. A compound(s) responsible for the inhibition and stimulation was extracted from A. bisporus culture filtrate and from compost-grown fruit bodies with n-butanol, but the identity of the compound(s) was not determined. We suggest that the stimulation of Th2 by metabolites produced by A. bisporus and the relatively low level of inhibition of A. bisporus by Th2 facilitate colonization of compost by both fungi. However, as compost colonization reaches a maximum, a change in the competitive balance in favor of Th2 results in the inhibition of fruit body production by A. bisporus and the devastating green mold epidemics affecting mushroom production.

The paper concerns randomly amplified polymorphic DNA RAPD-PCR analysis of seven Trichoderma species isolates and their in vitro antagonism against wilt pathogens of Psidium guajava L. viz. Fusarium oxysporum f. sp. psidii (F. o. f. sp. psidii) and Fusarium solani. Out of 10 RAPD oligonucleotides (OPA 1-OPA 10) tested, seven markers OPA 1, 3, 5, 7, 8, 9 and 10 efficiently differentiated the isolates of Trichoderma and showed reproducible banding patterns. A total of 248 bands were obtained from these markers along with a 61.84% per cent similarity among the seven isolates of Trichoderma. From the seven isolates of Trichoderma, isolates T. harzianum, T. virens and T. viride were evaluated for in vitro efficacy against F. o. f. sp. psidii and F. solani. Per cent inhibition was maximum by direct use of Trichoderma spp. in dual cultures against both pathogens, F. o. f. sp. psidii and F. solani. Two species, T. virens and T. viride were superior in inhibiting the growth of both Fusarium spp. Fusarium isolates showed intra species variability.
