概括
消耗的基板 (SMS) 可以取代黑兵 (Hermetia illucens) 幼虫的高达20%的料. 这种替代,特别是在最佳密度下,维持了幼虫的生长,并改善了废物减少,提供了可持续的料替代品.
科学领域:
- 农业科学 农业科学
- 昆虫学 昆虫学是一门学科.
- 废物管理 废物管理
背景情况:
- 消耗的基板 (SMS) 是一种易于获得的农业副产品.
- 黑兵 (Hermetia illucens) 幼虫是有机废物的有效生物转化器.
- 优化幼虫料的成分和密度对于有效的废物生物转化至关重要.
研究的目的:
- 评估用Pleurotus eryngii和Lentinula edodes SMS替代料对黑士兵幼虫的影响.
- 为了确定不同水平的SMS养的幼虫的最佳养密度.
- 评估对幼虫发育,生物量,组成和基质减少的影响.
主要方法:
- 在200-1000幼虫/盒的密度下,幼虫被食0-100%的SMS替代性饮食.
- 测量的关键绩效指标包括生存率,幼虫体重,生物量,生长率 (LGR),料转化率 (FCR) 和废物减少.
- 分析了幼虫的化学成分 (灰,脂肪,蛋白质).
主要成果:
- 生存没有受到影响,但高SMS水平降低了生长. 20%的SMS替代显示了与特定密度的控制饮食相匹配的结果.
- 随着SMS替代的增加,幼虫体重和生物量下降,除了20%之外.
- 最佳密度 (250个幼虫/盒子) 使用20%的SMS提高了基质减少和废物减少指数 (WRI),同时产生含蛋白质更高的幼虫.
结论:
- 在不影响繁殖效率的情况下,高达20%的料可以用SMS替换黑兵幼虫.
- 幼虫的表现和废物转化受SMS含量水平和库存密度的影响.
- 在昆虫养殖中,SMS显示出作为一种可持续且具有成本效益的料成分的潜力.

Microbial Bioremediation of Pesticides
85
Pesticides often feature structurally complex chemical architectures, incorporating halogen groups and multiple aromatic rings. These characteristics confer high chemical stability, rendering many pesticides resistant to natural degradation processes. This resistance poses significant environmental concerns, as persistent pesticide residues can accumulate in ecosystems and affect non-target organisms.Despite the inherent stability of many pesticides, certain microorganisms possess the metabolic...

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...

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...

Polyethylene terephthalate (PET) is a synthetic polymer widely utilized in the packaging industry, particularly for bottles and containers. Due to its chemical stability and durability, PET accumulates in the environment, contributing significantly to plastic pollution. It comprises repeating units of terephthalic acid and ethylene glycol, resulting in a semi-crystalline structure that is resistant to natural degradation processes.A notable breakthrough in plastic biodegradation came with the...
