Research ArticleOpen accessIn the abstractIsolation and Identification of Bacteria Leading to Microbial Spoilage of Sweet Potato and Screening for Antistaling Agents Running HeadDaoqi Liu, Huili Liu, Yuanyuan Dang et al.To develop natural preservatives tailored for sweet potatoes, the control effect of essential oils on the spoilage microorganisms of sweet potatoes is uncertain. Therefore, we first isolated and identified the dominant spoilage bacteria from spoiled sweet potatoes. Micrococcus aloeverae, Priestia aryabhattai, and Glutamicibacter arilaitensis were identified through screening, morphological observation, gram staining, and 16S rDNA assays. Subsequently, five plant essential … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 1 · 26 Apr 2024 · 5,221 accessesView PDFCite
Research ArticleOpen accessIn the abstractStress Resistance Physiological Traits in Maize Under High-Concentration Salt StressMingxia WangTo quantitatively analyze the stress-resistant physiological characteristics of maize under high-concentration salt stress, a combination of statistical analysis and quantitative recursive analysis is selected to conduct salt stress experiments on maize seedlings. 20 treatments are set up, with each treatment consisting of 5 pots and 3 plants per pot. The experiment is conducted without the involvement of any animals. Physiological … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 1 · 26 Apr 2024 · 4,868 accessesView PDFCite
