Abstract

Using decomposers of fungi to increase the composting process is very necessary. The research aims to determine the potential of Trichoderma sp. Gorontalo local isolate as a decomposer of maize stover. The research was carried out from November 2022‒January 2023 at the Biological Agents Laboratory, Agricultural Plant Protection Center, Gorontalo Province Agricultural Department. This research determined the ability of six isolates of Trichoderma, namely TZ11DI1 (T. asperellum), TZ21BN2 (T. breviconvenctum), TZ21BT1 (T. virens), TZ12PO1 (T. ghanence), TZ21DU1 (T. reesei), TZ21LU1 (T. dorothopsis), and control (EM4) to produce cellulase and as a maize stover decomposer. The parameters observed were the clear zone in the isolate growing media as well as the physical and chemical characteristics of the compost produced. The results showed that Trichoderma isolates produced cellulase and potential as a decomposer for maize stover, as indicated by the ability to increase NPK nutrient levels and reduce the C/N ratio of maize stover compost. Keywords: compost, decomposer, maize stover, Trichoderma

戈隆塔洛本地毛霉作为玉米作物废弃物分解者的潜力

使用真菌分解者来增加堆肥过程是非常必要的。本研究旨在确定戈伦塔洛当地分离的毛霉作为玉米秸秆分解者的潜力。研究于 2022 年 11 月至 2023 年 1 月在戈伦塔洛省农业部农业植物保护中心生物制剂实验室进行。这项研究确定了六种毛霉分离株，即 TZ11DI1（T. asperellum）、TZ21BN2（T. breviconvenctum）、TZ21BT1（T. virens）、TZ12PO1（T. ghanence）、TZ21DU1（T. reesei）、TZ21LU1（T. dorothopsis）和对照（EM4）产生纤维素酶和作为玉米秸秆分解者的能力。观察参数包括分离菌生长介质中的透明区以及所产生堆肥的物理和化学特性。结果表明，分离出的毛霉能产生纤维素酶，并具有作为玉米秸秆分解者的潜力，这表现在它能提高玉米秸秆堆肥的氮磷钾养分水平并降低其 C/N 比值。关键词：堆肥、分解者、玉米秸秆、毛霉菌
