摘要

Rhizoctonia solani is a soil pathogen that causes diseases in wide range of hosts of agricultural, horticultural and flower crops. Biological control is the most promising way for the diseases management and it is environment friendly too. The objective of this study was to isolate and screen the potency of soil bacteria as biological control from various local compost and peat soil of tropical peat swamp forest in Kalampangan Zone, Central Kalimantan. Forty seven isolates from peat soil and compost were screened for biocontrol agent of Rhizoctonia solani . R. Solani Seven out of thirteen peat soil isolates, and six out of thirty three compost isolates showed antagonistic activity against in Potato Dextrose Agar. The cultivation of the antagonistic isolates in Trypticase Soy Broth (TSB) was extracted and analysed by high performance liquid chromatography (HPLC) column. The HPLC analyzes indicated that the antagonistic isolates produce an antifungal iturin A. Macroscopic observation of isolates colonies showed that form of their colonies were amuboid, myceloid, curled, circular, rhizoid, irregular and filamentous. These achievement indicate peat swamp forest not only offer a potential biocontrol agents of damping off but also provide a new source for production of antibiotics.

Solani）十三种泥炭土壤分离物中有七种，三十三种堆肥分离物中有六种显示出对马铃薯葡萄糖琼脂的拮抗活性。提取胰蛋白酶解大豆肉汤（TSB）中的拮抗菌株，并通过高效液相色谱（HPLC）柱进行分析。 HPLC分析表明拮抗的分离物产生抗真菌的iturinA。对分离物菌落的宏观观察表明，其菌落的形状为阿米伯样，髓样，卷曲，圆形，类根状，不规则和丝状。这些成就表明，泥炭沼泽森林不仅提供了潜在的生物防治剂，而且还提供了生产抗生素的新来源。
