“…Based on these results, the stain fungi isolates that we obtained from the rubberwood are different from those found by OldertrØen et al (2016) which were Aspergillus niger, Aspergillus flavus, and Penicillium citrinum; and also different from those found by Razali et al (2016) which were Fusarium equiseti, Mucor irreguralis, and Lasiodiplodia theobromae. However, some results still showed similarities in genus level.…”

“…Valiante et al (2016) argued that discoloration is caused by pigmentation on the hyphae or melanin synthesis on the conidia during sporulation process. Previous studies reported that three stain fungi species were identified from rubberwood, which were Aspergillus niger, Aspergillus flavus, and Penicillium citrinum (Oldertrøen et al 2016). Meanwhile, Salman et al (2020) reported that at least there were two stain fungi isolated from air dried rubberwood which will be processed for furniture products in West Java Province, Indonesia, which were Aspergillus aflatoxiformans and A. foetidus.…”

Abstract. Nandika D, Arinana, Salman ABA, Putri JY. 2021. Morphological and molecular features of stain fungi infecting rubberwood (Hevea brasiliensis). Biodiversitas 22: 5408-5416. In the southeast Asia region, particularly Indonesia, Thailand, and Malaysia, rubberwood (Hevea brasiliensis Muell. Arg.) has been widely used as a raw material in various industries particularly furniture manufacturing. However, rubberwood is highly susceptible to fungal attack due to its lack of heartwood formation. A laboratory study was conducted to investigate the morphological and molecular features of stain fungi infecting rubberwood. A total of five isolates of stain fungi belonging to three genera were identified based on internal transcribed spacer (ITS) and morphological features. All isolates belong to Order Eurotiales with each genus being Paecilomyces, Aspergillus, and Penicillium. The highest growth rate on wood samples was shown by Aspergillus chevalieri section Aspergillus and Paecilomyces maximus or P. formosus with values of 86.57% and 86.22%, respectively. All of the stain fungi genera caused varied level of discoloration on wood samples with dark grayish and very dark grayish as the more frequent color found. Quantitatively, the highest discoloration was shown by A. chevalieri section Aspergillus (?E = 27.60) and P. maximus or P. formosus (?E = 16.69). These species can be considered as newly stain fungi recorded infecting rubberwood in Indonesia. In addition, discoloration caused by these two stain fungi was the worst.

Recently, the architectural and physical properties of the fungus comb from subterranean termite Macrotermes gilvus Hagen (Isoptera: Termitidae) mounds had been studied and it is important to determine its chemical profile as well as to evaluate its anti-staining-fungi activity. The results showed that fungus comb of M. gilvus has a high crude ash (30.57%), fiber (25.46%), starch (7.76%), protein (5.80%, 5.53% amino acid), acid-insoluble ash (3.45%), and fat (0.73%). It also contained phenol hydroquinone, steroids, terpenoids, and saponin compounds. Seventeen amino acids were identified via high-performance liquid chromatography analysis, of which arginine, leucine, glutamate, and aspartic acid were the majority. According to gas chromatography-mass spectrometry analysis, the n-hexane extract consists of several types of fatty acid derivatives. Meanwhile, the ethyl acetate (EtOAc) extracts were primarily phenol groups with 1,2,3-propanetriol (glycerol) at the highest relative concentration. Four fungus-comb extracts (n-hexane, EtOAc, MeOH, and water) inhibited the Aspergillus foetidus fungus, with inhibition rates ranging from 24.17% to 100% and EtOAc extract as the most active extract. It appears that EtOAc extracts from the M. gilvus fungus comb can be considered an active ingredient source of novel organic fungicide in preventing wood-staining fungi attacks on susceptible wood.

“…Stain fungi do not affect of strength loss, but decrease the aesthetic and cost of wood. Previous studies reported that three stain fungi were identified from rubberwood, which were Aspergillus niger, Aspergillus flavus, and Penicillium citrinum (Oldertrøen et al 2016). In fact, stain fungi were found to attack the part of piano produced by one company in Indonesia.…”

Abstract. Salman ABA, Sudirman LI, Nandika D. 2020. Selection of stain fungi on rubberwood (Hevea brasiliensis) and its growth response against chitosan. Biodiversitas 21: 4501-4508. Rubberwood (Hevea brasiliensis Muell. Arg.) is one of the most important raw materials in furniture industry in South East Asian countries, particularly in Indonesia, Thailand and Malaysia. However, due to its susceptibility to stain fungi attack, wood preservative is needed to processing this material, which has both significant cost and environmental implications. A laboratory study was conducted to identify the seasoned rubberwood attacking stain fungi and to evaluate the bioactivity of chitosan in inhibiting the stain fungi’s growth. Isolation fungi from seasoned rubberwood were obtained firstly then selection isolates were conducted in the rubberwood test samples. Isolates with the highest percentage growth on wood test samples would identify based on internal transcribed spacer (ITS) region. Chitosan were prepared in four concentration 0, 0.5, 1 and 2% (w/v). Two isolates were showed the highest percentage growth on wood test samples after six weeks, which were 90.6% for isolate code I4 and 96.2% for II4 and both isolates gained scores 5. The two isolates were identified as Aspergillus foetidus for I4 and Aspergillus aflatoxiformans for II4. Aspergillus foetidus and A. aflatoxiformans would be the newly recorded species and this is the first report about species description from rubberwood in Indonesia. The inhibition rate was increased when chitosan concentration was increased from 0 to 2%. Chitosan concentration 2% inhibited the growth of A. foetidus in 20.28%, but there is no inhibition showed on A. aflatoxiformans. The addition of chitosan in medium can increase the growth of A. aflatoxiformans and forming clear zone around the colony.
