“…The prospect of employing these AgNPs as a broad-spectrum antimicrobial agent was clearly recognized by these results. This experiment is in correspondence with the view of [4] that the probable antimicrobial potential of AgNPs is because of their higher surface-to-volume ratio and their crystalline structure [24]. The AgNPs have been found to rupture the cell membrane, resulting in the generation of reactive oxygen species (ROS) that damage the DNA and proteins, followed by the microorganism's destruction [25].…”

The silver nanoparticles were biosynthesized using fungal isolates as well as their mixed cell free filtrate acting as a consortium namely, DS-2 (Penicillium oxalicum), DW-8 (Fusarium hainanense) and DSW-28, respectively. The UV-Visible spectra determined the surface plasmon resonance at 438, 441 and 437 nm for the silver nanoparticles synthesized by DS-2, DW-8 and DSW-28, respectively. The Tauc’s plot analysis disclosed the band gap energy between 2.21 eV to 2.24 eV which depicted their ability to act as a semiconductor. The TEM imaging revealed the spherical shape along with the average particle size of DS-2 as 11.14 ± 2.39 nm and DW-8 as 7.59 ± 1.31 nm whereas that of DSW-28 as 5.73 ± 0.4 nm. Thus, the silver nanoparticles synthesized by DSW-28 were smaller in size than the individual isolates. The XRD pattern of the silver nanoparticles exhibited the crystalline structure corresponding to their peaks. The FTIR spectra indicates the presence of different functional groups on the surface of the synthesized silver nanoparticles. The broad-spectrum antimicrobial activity was exhibited by silver nanoparticles synthesized by DSW-28 against Gram positive, Gram negative bacteria and plant pathogen Fusarium oxysporum than the individual fungal isolates. The DSW-28 synthesized silver nanoparticles also acts as an effective antioxidant by depicting their radical scavenging activity against DPPH. Moreover, the silver nanoparticles synthesized by DSW-28 also inhibited the growth of 4th instar larvae of Aedes aegypti and Culex quinquefasciatus more efficiently than DS-2 and DW-8 in a dose-dependent method. The impressive bioactivity of the silver nanoparticles synthesized by the mixture of cell free filtrate of various fungi acting as a consortium recommends their prospective use in agriculture as well as in biomedical as an antimicrobial, antioxidant and larvicidal agents in future.

“…Thraustochytrium striatum is reported to have antibacterial activity against Pseudomonas aeruginosa [26]. The activity varies with the crystallographic nature of nanoparticles [52]. However, the antimicrobial activities of silver and gold nanoparticles synthesized from Thraustochytrium kinnei were compared with distilled water as a negative control, which had no bacterial inhibition (data not shown).…”

This work deals with the identification of a predominant thraustochytrid strain, the optimization of culture conditions, the synthesis of nanoparticles, and the evaluation of antioxidant and antimicrobial activities in biomass extracts and nanoparticles. Thraustochytrium kinnei was identified as a predominant strain from decomposing mangrove leaves, and its culture conditions were optimized for maximum biomass production of 13.53 g·L−1, with total lipids of 41.33% and DHA of 39.16% of total fatty acids. Furthermore, the strain was shown to synthesize gold and silver nanoparticles in the size ranges of 10–85 nm and 5–90 nm, respectively. Silver nanoparticles exhibited higher total antioxidant and DPPH activities than gold nanoparticles and methanol extract of the strain. The silver nanoparticles showed higher antimicrobial activity than gold nanoparticles and petroleum ether extract of the strain. Thus, Thraustochytrium kinnei is proven to be promising for synthesis of silver nanoparticles with high antioxidant and antimicrobial activity.

“…In addition to plant extract directly loading AgNPs, NPs fixed with marine endophytic fungi show a significant role in the medical industry, ensuring the development of a novel broad‐spectrum antimicrobial agent (Manjunath Hulikere & Joshi, 2019). The antimicrobial study on AgNPs of a red algae Gelidium corneum extract exhibited MIC value of 0.51 µg/mL for C. albicans and 0.26 µg/mL for E. coli (Öztürk et al., 2020), while AgNPs produced from marine Streptomyces sp.…”

Botanic bioactive substances have issues with their solubility, stability, and oral bioavailability in the application, which could be improved by nanotechnologies. In another hands, green synthesis of nanoparticles (NPs) with plant extract is also a promising technology for preparation of NPs due to its safety advantage, yet the bioactive botanic substances that could be more than the assistant of the green synthesis of NPs. Based on the above concerns, this review summarized the preparation of botanic NPs with various plant extract, their solubility, stability, and oral bioavailability; specific attention has been paid to the botanic Ag/Au NPs, their capacity of antioxidant, bioavailability, antimicrobial, anti‐inflammatory, and anticancer.
