tailieunhanh - Isolation and selection of fungal species from the compost with the cellulolytic activity and resistance topathogenic phythium and phytophthora capsici fungi on the pepper plants

This research focuses on identification of the mold species isolated from the compost, and investigation of their cellulolytic activity, inhibitory or resistant abilities to fungal diseases on the pepper tree (Piper nigrum), in order to produce biological products for fertilization. | TRƯỜNG ĐẠI HỌC SƯ PHẠM TP HỒ CHÍ MINH TẠP CHÍ KHOA HỌC HO CHI MINH CITY UNIVERSITY OF EDUCATION JOURNAL OF SCIENCE KHOA HỌC TỰ NHIÊN VÀ CÔNG NGHỆ NATURAL SCIENCES AND TECHNOLOGY ISSN: 1859-3100 Tập 14, Số 9 (2017): 160-169 Vol. 14, No. 9 (2017): 160-169 Email: tapchikhoahoc@; Website: ISOLATION AND SELECTION OF FUNGAL SPECIES FROM THE COMPOST WITH THE CELLULOLYTIC ACTIVITY AND RESISTANCE TOPATHOGENIC PHYTHIUM AND PHYTOPHTHORA CAPSICI FUNGI ON THE PEPPER PLANTS Le Hung Anh1*, Nguyen Hoang My1, Mai Quan Thai1, Tran Xuan Ngoc Anh 2, Au Thi Hanh3, Phan Thi Phuong Trang3 1 Industrial University of Ho Chi Minh City LEFAN Science Service and Biotechnology Co.

However, pepper farms are usually threatened with diseases, causing deaths over the large areas. The main features of pepper diseases are the abilities to spread rapidly and cause mass death, without recovery or prevention methods. Therefore, the research and production of biological products are essential to prevent, inhibit and resist to fungal diseases. This research focuses on identification of the mold species isolated from the compost, and investigation of their cellulolytic activity, inhibitory or resistant abilities to fungal diseases on the pepper tree (Piper nigrum), in order to produce biological products for fertilization. The results showed that, 2 strains (C1-1 and C1-2) of Aspergillus oryzae was isolated and identified had the fungal resistance to Phytophthora capsici and Pythium, which cause rapid death on the pepper. Therefore, these types of molds can be combined to produce biological products for practical use in agriculture. Keywords: Aspergillus oryzae, resist, pepper, fungus, compost, inhibit.
