Fluorescence, infrared, scanning electron microscopy (SEM), UV-visible, and X-ray diffraction (XRD) techniques have been applied to monitor the effect of processing mode on the residual cyanogens in cassava roots. The processed samples' infrared spectra have shown that only the boiled sample contains residual cyanide. SEM micrographs have revealed that irregularly shaped granules of about 100-microm size contain cyanide, while spherical granules of about 10-microm size do not. X-ray diffraction patterns have shown that the intensities of peaks are not affected by the presence of cyanide in the cassava samples. Fluorescence and UV-visible studies have detected the presence of cyanide converted to cyanate in water used for soaking processes. The thermal behavior of cassava samples with respect to the cyanide content and the role of oxygen and different ions present in water used for soaking processes are also discussed.

Article Synopsis
- Sodium nitroprusside (SNP) is identified as a beneficial donor of nitric oxide that enhances plant resistance against abiotic stress, specifically aiding in alleviating cadmium (Cd) toxicity in tobacco plants.
- The study demonstrated that 150 μM SNP effectively restored stress tolerance indicators in cadmium-stressed seedlings and promoted the accumulation of antioxidants while activating key antioxidant enzymes.
- Additionally, SNP improved Cd sequestration in the root cell wall, reducing its translocation to shoots and converting it into less toxic forms, which could inform strategies for developing low-cadmium tobacco.

Article Synopsis
- This study aimed to find the best conditions for using bioreactor systems to treat industrial wastewater containing metal cyanide, focusing on aerobic and anoxic environments.
- Initial findings showed that bacteria performed better in aerobic conditions, leading to a 30-day long-term study where high removal rates of cyanide and metals were observed, especially in the first week.
- Overall, the research demonstrated that the right aeration and carbon sources boosted bacterial efficiency, with cyanide being removed more effectively than other metals, indicating that the bacteria could withstand heavy metal toxicity.

Article Synopsis
- - The study investigated the respiratory activities of mitochondrial complexes I, II, and IV in both permeabilized cells and isolated mitochondria, revealing consistent substrate affinities across both settings.
- - Activity analysis showed that extracted mitochondria from Antarctic yeast retained functionality for key electron transport chain components (Complexes I, II, III, and IV) and formed supercomplexes of I, III, and IV, though traditional methods didn’t reveal the functional states of ATP synthase.
- - Additional pathways for NADH oxidation were identified, including alternative dehydrogenases, and cyanide exposure pointed to the potential presence of an alternative oxidase contributing to residual cellular respiration.
Entrapment of Cyanase from Using Biomimetic Silica and Its Application for Cyanate Bioremediation.
Polymers (Basel)
September 2024
Department of Chemical Engineering and Biotechnology, Tatung University, No. 40, Sec. 3, Zhongshan N. Rd., Taipei 104, Taiwan.
Article Synopsis
- Cyanate, a harmful byproduct from cyanide oxidation, can be safely turned into ammonia and carbon dioxide using an enzyme called cyanase, which was improved for stability and reusability by trapping it in biomimetic silica.
- The entrapped cyanase exhibited double the enzyme activity and maintained better performance at elevated temperatures and after a month at room temperature compared to the free enzyme.
- By co-entrapping another enzyme, carbonic anhydrase, the process for detoxifying cyanate was made more efficient, requiring less bicarbonate and maintaining significant effectiveness even after five reuse cycles.
