  据介绍,本次大赛旨在引导大学生自主学习生物化学等相关生命科学知识,培养大学生创新意识和实践能力,深化大学生创新创业教育,提高人才培养质量。

  大赛自6月底启动以来,本届大赛共收到来自广东省50所高校753支参赛队伍的实验项目书,各高校遴选推荐249支队伍进入省赛初赛。在初赛评审环节,专家评委共评审出91个项目进入拟获奖名单,确定三等奖项目,并推荐35支本科组、10支高职高专组进入线下决赛角逐一、二等奖。

  其中,华南农业大学的项目针对香蕉枯萎病这一严重威胁香蕉种植产业的病害,结合核酸恒温扩增技术(RPA)及CRISPR/Cas12a技术开发了一种裸眼快速可视化检测系统。该系统可以在恒温条件下快速检测香蕉枯萎病主要致病菌株Foc TR4的特异性序列,并通过溶液颜色将检查结果可视化,能够为香蕉枯萎病的现场检测提供依据,也可以为其他动植物病害的现场检测提供参考。

  暨南大学的项目设计了一种基于壳聚糖和花青素的pH保鲜膜,可以帮助人们通过手机APP分析薄膜的颜色参数,从而监测肉的新鲜度,为肉类产业提供一种快速准确的实时肉类新鲜度评估方法。

  汕头大学的项目以广泛分布于东南沿海地区的龙须菜为原料,提取制备海藻低聚糖,将其与益生菌结合联合开发新型“合生元”酸奶,提升酸奶营养价值与健康功效。

  广东科贸职业学院的项目采用水淬离心法提取夏威夷果油体,并利用-卡拉胶和魔芋胶的协同增效作用提高油体稳定性,在此基础上包埋香兰素,并通过喷雾干燥工艺制得夏威夷果奶香乳粉,提高夏威夷果的开发应用率。(完)
