ISOLATION AND SELECTION OF AFLATOXINS PRODUCING ASPERGILLUS FLAVUS FROM PEANUT

Aspergillus flavus is known as the main producer of carcinogenic aflatoxins. The presence of this fungus and aflatoxins is an important impactson food safety, human and animal health. Peanut is one of the most important crops in Vietnam and  is suitable to substrate for aflatoxins producing fungus growth. The isolation and identification of Aspergillus flavus species from peanut is an initial step for further study in Aflatoxins contamination control in peanut. 28 peanut samples selected in Luc Nam district - Bac Giang province were used for fungus isolation. The isolated fungus were purified, conducted DNA extract, amplified PCR products then performed sequencing ITS gene and used BLAST software to check alignment to identification the strains. As the result, 4 strains alignedwith Aspergillus flavus strains from National Center for Biology Information - United Nation such as: TUHT115, KP214054.1, MTCC 8654, ZJ4-A. Those strains were checked and confirmed the aflatoxins production in peanut samples

EFL students as creative writers

This article aims to share the author’s mini-action research in using some creative writing activities with Vietnamese high school students to examine how creative these EFL students could be in their writing of English and how useful creative writing can be to them. Three teaching activities were tried out as warmers with two groups of students in three different English sessions within two weeks. The outcome showed that these high school students were able to write creatively and their products could contribute to consolidating the benefits of creative activities in enhancing students’ mental and emotional development as advocated in various EFL contexts (Avramenko et al., 2018; Maloney, 2019; Manara, 2015; Pawliczak, 2015; Rippey, 2014; Şenel, 2018)
