The potential of Trichoderma spp. and Pseudomonas auregenosa as patchouli waste decomposer

Abstract

Currently, waste from patchouli distillation process is unutilized. It is known that the waste still has high nutrient content and has the potential as raw material for organic fertilizers. In this study, we investigated the potential of Trichoderma harzianum, T. asperelum, and Pseudomonas aeruginosa as biodecomposer in patchouli waste composting process. The bio decomposers were inoculated to patchouli waste to determine the effect on composting process time, maturation and compost chemical properties. T. harzianum and T. asperelum were added to the compost raw material in the form of pellet (15 g). While P. aeruginosa added suspension at 108 as much as 20 ml. The results showed that the inoculation of T. harzianum, T. asperelum and P. aeruginosa accelerated the decomposition process and improved the compost texture. Chemical properties analysis indicated that the compost produced meet Indonesia compost standarisation. This study revealed that T. harzianum, T. asperelum and P. aeruginosa are potential patchouli waste decomposers.

Effects of Silicon Alone and Combined with Organic Matter and Trichoderma harzianum on Sorghum Yield, Ions Accumulation and Soil Properties under Saline Irrigation

“…Adding organic matter can mitigate the effect of salts and improve plant growth, as it is a source of nutrients, increasing their availability, while also increasing water retention, improving soil structure, and increasing the bioactivity of microorganisms [61,62]. The action of Trichoderma may be associated with the fungus' ability to increase the availability of nutrients in the soil through the secretion of organic acids into the root environment, as well as acting as a decomposer and mineralizer of OM, releasing the nutrients present in it more quickly [63][64][65][66].…”

Wood decomposers on six community timber species in two different locations

“…macroscopically has greenish colonies with thin mycelium and a fast-growing power, while microscopically, it has hyphae insulated with erect mycelium and round-shaped conidia. Moreover, Pratiwi et al (2021) state that Trichoderma decomposes organic material in 36-45 days. In degrading the cell wall material that Trichoderma decomposes, the fungus uses cellulase, xylanase, and glucanase enzymes (Zin and Badaluddin 2020).…”

Potensi Trichoderma sp. Indigenus Gorontalo sebagai Dekomposer Limbah Tanaman Jagung

“…Kemampuan menghasilkan selulase ini berkaitan erat dengan perannya sebagai dekomposer selulosa di alam (Singh et al 2016). Bridziuviene et al (2022) melaporkan bahwa T. ghanense sangat efektif mendekomposisi selulosa bahan organik, T. asperellum sangat potensial sebagai dekomposer limbah nilam (Pratiwi et al 2021), dan T virens mampu mendekomposisi kotoran ternak (Rosmini et al 2020).…”
