The Use of Fungal Endophyte Penicillium citrinum on Tree Seedling: Applicability and Limitation

Abstract

Penicillium citrinum is an endophyte fungus isolated from plant tissues that live in tropical peatland. Various study reveals that endophytic fungi give advantages to plant health. Since 2015, series of experiments were conducted to investigate the capability of P. citrinum P3.10 as biofertilizer of plant tree in nursery stage which are: pathogenicity test, in vitro assay, direct application to seeds, dosage test, and fertilizer formulation. This paper presents a review from our research of P. citrinum isolate P3.10 from the isolation stage to the biofertilizer product formulation. Resear ch results showed that the application of endophytic fungi to seedlings gave positive responses. However, during the research process there were also obstacles in the application of endophytic fungi to plants, which are: (a) difficulties in application due to the varied response, (b) formulation, (c) storage, (d) isolate viability, and (d) fungal isolate maintenance. Risk management was needed during biofertilizer production. Hence, the utilization of biofertilizer made from endophyte fungi is applicable and can be used not only on an experimental scale but also on a larger scale.

The Effect of Endophytic Talaromyces pinophilus on Growth, Absorption and Accumulation of Heavy Metals of Triticum aestivum Grown on Sandy Soil Amended by Sewage Sludge

“…Our results showed a significant increase in water content, dry mass, photosynthetic pigments, some osmolytes and enzymatic antioxidants. These findings are consistent with those of [67]. This study found that many endophytic fungi might significantly boost the root-dry biomass of maize at higher Zn and Cd contents.…”

Isolasi dan Identifikasi Cendawan Endofit Akar Anggrek Epifit dan Hemiepifit

“…Avila-Diaz et al (2013) juga melaporkan bahwa P. citrinum juga ditemukan pada anggrek epifit Laelia speciosa (HBK) Schltr asal Meksiko. Beberapa peran P. citrinum diantaranya ialah menghasilkan giberelin dan sitokinin (Gu et al 2023), meningkatkan penyerapan nutrisi dan pertumbuhan tanaman (Hakim & Yuwati 2020), memproteksi tanaman terhadap cekaman biotik (Waqas et al 2015), serta memproduksi senyawa anticendawan dan antimikrob lainnya yang bermanfaat dalam bidang pertanian, farmasi, dan bioteknologi. Penicilium citrinum juga berpotensi sebagai antikanker, antivirus, antioksidan dan antiinflamasi (Toghueo & Boyom 2020).…”
