- Botrytis cinerea会导致灰色腐烂,这是草中一个重要的收获后疾病.
- 植物提取物被探索为合成农药的天然替代品,用于食品保存.
研究的目的:
- 评估生物降解薄膜的有效性,其中包括来自巴西植物 (Trichilia catigua,Paullinia cupana,Stryphnodendron barbatiman,Caesalpinia peltophoroides) 的提取物,用于保存草.
- 评估这些植物提取物对草关键质量参数的影响.
主要方法:
- 草被涂上含有各种植物提取物的可生物降解薄膜.
- 随着时间的推移,测量了质量损失,pH,总酸度 (TA),可溶性固体和颜色参数 (亮度,红色强度).
- 用提取物处理的样本与未处理的对照样本进行了比较.
主要成果:
- 在提取物处理和对照草之间观察到质量损失的显著差异.
- pH,TA和可溶性固体在治疗过程中显示出一致的显著平均值.
- 亮度一般增加,除了瓜拉纳涂层样本. 红色的强度得到了增强,除了巴巴蒂马昂提取物.
结论:
- 含有Trichilia catigua,Paullinia cupana,Stryphnodendron barbatiman和Caesalpinia peltophoroides的提取物的生物降解膜可以提高草的保存.
- 这些天然涂层代表了传统农药的可行替代品,可以改善草的保质期和质量.

01:27Bioplastics
Bioplastics derived from microbial processes present a sustainable alternative to conventional petroleum-based plastics. Among these, polyhydroxyalkanoates (PHAs), particularly polyhydroxybutyrates (PHBs), have emerged as prominent candidates due to their biodegradability and biocompatibility. These polymers are synthesized by a variety of bacteria, such as Cupriavidus necator and Pseudomonas putida, which naturally accumulate PHAs as intracellular carbon and energy reserves, especially under...

Biopesticides offer a sustainable alternative to chemical pesticides, utilizing microbial agents to control agricultural pests. Bacillus thuringiensis (Bt) is a widely employed bacterium known for its potent insecticidal activity. Bt biopesticides are favored for their specificity to insect pests, minimal environmental impact, and natural degradability.Mechanism of Bt Toxin Action Bt produces insecticidal crystal (Cry) proteins during its sporulation phase. These proteins form parasporal...
