“…However, several studies indicate Aspergillus flavus is able to inhibit the growth of Septobasidium sp. and also has the potential to act as a biological agent (Suswanto et al 2018), in addition to absorbing chromium, and is, therefore, suitable for processing waste containing hexavalent chromium (Vinay and Dwivedi 2019) and increasing tomato's resistance to blight (Abdel Motaal et al 2020). Reports by Berg and Hallmann (2006), as well as Sucipto et al (2015) show endophytic fungi's mechanism of direct inhibition against pathogens is through antibiosis, competition, as well as lysis, while the indirect mechanism involves inducing plant resistance and increasing plant growth.…”

Abstract. Syamsia S, Idhan A, Firmansyah AP, Noerfitryani N, Rahim I, Kesaulya H, Armus R. 2021. Combination on endophytic fungal as the Plant Growth-Promoting Fungi (PGPF) on Cucumber (Cucumis sativus). Biodiversitas 22: 1194-1202. Endophytic fungi are known to stimulate plant growth by producing secondary metabolites, including phytohormones (IAA and Gibberellins), siderophore, phosphate-solubilizing metabolites. In this study, a total of six endophytic fungi were successfully isolated from local rice plants and showed different abilities in producing secondary metabolites, during single isolates testing. These six isolates were then combined to obtain 15 combinations for analysis, to determine the best combination for application as a plant growth promoter. Subsequently, each combination was tested for phytohormones (IAA, gibberellins) and siderophore (quantitatively)-producing activity, phosphate-solubilizing ability, and the effect on cucumber (Cucumis sativus L) plant growth. F13 showed activity in producing IAA and produced the highest gibberellin levels, while F1 exhibited the highest phosphate-solubilizing activity. In addition, F11 (Na-salicylate) and F1 (catechol) showed the highest siderophore activity, while a combination of F6, F8, F9, and F12 successfully increased plant height growth. Also, F4 increased the root growth, while the fresh weight of cucumber was increased by F8 treatment, under controlled conditions. Molecular analysis showed the tested isolates have close similarity to Daldinia eschscholtzii, Sarocladium oryzae, Rhizoctonia oryzae, Penicillium allahabadense, and Aspergillus foetidus. The combination of endophyte fungal isolates showed potential as plant growth promoters, however, further testing on several plant types is required before the combination is to be widely applied.

Chlorpyrifos is one of the broad-spectrum organophosphate insecticides in controlling plant pests. They can be absorbed into agricultural products and in the long term can have negative effects on human health. The use of endophytic fungi for biodegradation of chlorpyrifos is one of the technologies to support food safety. Therefore, this study was aimed to determine the potential of the isolated endophytic fungi and identify it from shallot plantations as biodegradation of chlorpyrifos. The research is conducted in three stages; (1) isolation of endophytic fungi on shallot plantations in Bantaeng Regency, (2) macroscopic and microscopic identification, and (3) test of the degradation potential of chlorpyrifos by growing fungi on PDA medium containing chlorpyrifos with concentrations 600 ppm, 300 ppm, and 150 ppm. Furthermore, the results showed there are 47 fungal isolates from the roots, stems and tubers of shallots, and some were identified as Trichoderma sp. and Fusarium sp. Several isolates tested have the potential to degrade chlorpyrifos, where the percentage of growth inhibition below 50% is considered tolerant of chlorpyrifos. Considering the results, Trichoderma sp. and Fusarium sp. are potential degrading residual insecticide chlorpyrifos.
