| description | A research on exploration of rhizosphere streptomycetes producing
antifungal on various plants (Cyperus rotundus L., Zea mays L., Rhizopora
mucronanata dan Rhizopora apiculata) was conducted. Seventeen isolates of
streptomycetes was tested to asses their potency in producing antifungal
compound by using agar block method with Aspergillus niger FNCC 0060, A.
terreus FNCC 0061, A. flavus NRRL 3357, Candida albicans ATCC 10231, C.
albicans ATCC 24433, Tricoderma reesei NBRC 31329, Fusarium oxysporum
KFCC 11363P, and Trichophyton consentricum A11 as test fungi. The result
showed that 10 isolates among 17 isolates showed their potency to produce
antifungal. Based on their antifungal activity, 2 isolates (J10 dan 41X) were
chosen to produce antifungal compound using fermentation method in GYE broth.
The medium then was extracted by using etil asetat. Characterization of antifungal
compound was carried out by using TLC and bioautography test. The result of
bioautography test showed that the spot from TLC of J10 and 41X isolates could
inhibit C. albicans ATCC 10231 dan T. reesei NBRC 31329 growth.
Identification of antifungal compoud of J10 and 41 isolated by using TLC analysis
and spray reagent sugessted that then alkaloid, flavonoid, and phenol class of
compound. Therefore, identification with GC-MS, the compounds were not be
able to determined. Characteritation and identification of isolates were based on
colour grouping, gram staining, morphology spora chain and spora surface
ornamentation. The result showed that J10 and 41X isolates were gram positif
bacterial, types of morphology spore chains were spiral to J10 and flexus to
isolate 41X, and spora surface ornamentation were both spiny. Based on their
spora chain morphology and spora surface ornamentation, isolate J10 was
putatively identified to be member of Streptomyces novaecaesareae and isolate
41X to be member of S. litmocidini. Therefore it could be concluded that
rhizosphere streptomycetes isolated from various plants were potencial to produce
antifungal compound. |
