“…TEM imaging showed the accumulation of silver particles due to silver exposure and abnormal intracellular appearances. Similar results exist for S. cerevisiae exposed to 2 mM AgNO 3 and the allergen 2S albumin [ 37 , 42 ]. Overall, TEM results indicated that NS commercial yeast had the capability to produce AgNPs after transient AgNO 3 exposure, even at a level of silver exposure that is detrimental to cellular growth, demonstrating S. cerevisiae suitability for AgNPs mycosynthesis.…”

“…The analysis produced results for NS commercial yeast; however, results for NS naïve yeast were inconclusive. Figure 6 a shows micrographs for NS commercial yeast unexposed to AgNO 3 ; typical morphology was observed, with no visible accumulation of any particles [ 37 , 38 ]. The corresponding energy-dispersive X-ray spectroscopy (EDS) spectrum showed no intracellular silver accumulation ( Figure 6 (a1)).…”

Silver nanoparticle (AgNP) production and their use as antimicrobial agents is a current area of active research. Biosynthesis is the most sustainable production method, and fungi have become candidates of interest in AgNP production. However, investigations into the physiological responses of fungi due to silver exposure are scanty. This present work utilized two strains of Saccharomyces cerevisiae (one used in commercial fermentation and a naturally occurring strain) to determine the physiological consequences of their transient exposure to AgNO3. The assessments were based on studies involving growth curves, minimal inhibitory concentration assays, scanning electron microscopy (SEM) and transmission electron microscopy (TEM) imaging, and inductively coupled plasma optical emission spectroscopy (ICP-OES). Results indicated (a) the capability of S. cerevisiae to produce silver nanoparticles, even at elevated levels of exposure; (b) strain origin had no significant impact on S. cerevisiae physiological response to AgNO3; and (c) coexposure to copper and silver significantly increased intracellular copper, silver, and calcium in treated yeast cells. In addition, electron microscopy and ICP-OES results revealed that both strains internalized silver after exposure, resulting in the shrunken and distorted physical appearance visible on SEM micrographs of treated cells. Though a promising candidate for AgNPs biosynthesis, this study analyzed the effects of transient silver exposure on S. cerevisiae growth physiology and morphology.

Moringa oleifera, or drumstick tree, is popularly known as the miracle tree. Almost every part of this tree is scientifically proven to be useful, be it root, bark, gum, leaf, fruit, flower, and seed. Over the years, many scientific studies have illustrated large bioactive compounds from Moringa oleifera extract. It is possible that the antifungal property of Moringa oleifera is closely associated with the presence of its bioactive compounds. However, this finding is limited to human studies and few on agricultural importance despite their potentiality. Nonetheless, various studies found good antifungal activity of Moringa oleifera extract, the promising results for the antifungal activity made it a good candidate to replace the synthetic fungicide. In this regard, this review focuses on using Moringa oleifera extracts as a potential biofungicide against the soil borne fungal disease that destroys most cash crops, especially chillies. Conclusively, this review outline the current state of knowledge and provides a compilation of evidence-based literature on Moringa oleifera extract to provide a reference for its potential application as biofungicide against soil borne fungal disease.
