“…2017). Ineterstingly, Chlorella extract has previously showed antibacterial activities (Acurio et al, 2018). Therefore, the beneficial rote of aqueous extract of both as biofertilizer and as antibacterial agent against Bacillus sp., Streptococcus sp., Staphylococcus aureus and E coli was investigated.…”

To investigate the dual beneficial effect of C. vulgaris as biofertilizer and antimicrobial agent in the form of nano particles. The antibacterial effect of aqueous extract was investigated by diffusion disk bioassay against five pathogenic bacterial strains. The plant growth promoting effect was investigated by performing germination tests on three types of seeds and measuring their morphometric growth parameters. The silver nanoparticles biosynthetic ability of alga was investigated by incubating with silver nitrate solution. The biogenic nanosilver was tested against multidrug-resistant Staphylococcus aereus(MRSA). The antibacterial effect of the extract, despite being derived from a miniscule biomass, was detected against all pathogenic strains. The inhibition zones ranged from 0.7 to 1 cm. In addition, the aqueous extract was effective bio-fertiliser that resulted in a significant increase in germination percentage and growth parameters of Eruca sativa, Lepidium sativum and Vigna radiata seedlings. Furthermore, the silver nanoparticles were observed to form both intra-and extracellularly. The UV-visible spectrum of nanoparticles showed a characteristic broad peak at 421-425 nm, while IR showed the presence of-1 characteristic signal at 3297cm. The nanosilver particles were effective antimicrobial agents against multi-drug resistant MRSA. The results emphasize the multiple potential of C. vulgaris, which indicates its great potential if grown on a large scale for mass production. The present research also sheds some light on the potential of microflora inhabiting this rather underexplored part of the world.

“…Some reported algicidal compounds are amylase, 2-undecen-1′-yl-4-quinolone, 2-undecyl-4-quinolone indole-3-acetic acid and octadecenoic acid [128]. Moreover, bactericidal substances such as chlorellin, secreted by microalgae, exhibit an inhibitory effect on both Gram-positive and Gram-negative bacteria [21,116,129]. Others compounds reported as relevant for cell to cell communication are indole-3-acetic acid (phytohormone) that stimulate the metabolism of microalgae, enhancing the interaction between microalgae and bacteria [118,130,131].…”

“…In Chlorella spp., a mixture of fatty acids, termed ‘chlorellin’ is known to have antimicrobial properties, and, for example, ethanol and isopropanol‐extracts from Chlorella spp. were shown to have inhibitory capacity equivalent to ampicillin and oxacillin against Staphylococcus spp., although this author did not investigate the effect of the individual fatty acids (Acurio et al ., 2018 ). Taken together, these results suggest that various microalgal fatty acids can exert antimicrobial activity, although PUFA appeared more likely to do so.…”

Microalgae comprise a phylogenetically very diverse group of photosynthetic unicellular pro-and eukaryotic organisms growing in marine and other aquatic environments. While they are well explored for the generation of biofuels, their potential as a source of antimicrobial and prebiotic substances have recently received increasing interest. Within this framework, microalgae may offer solutions to the societal challenge we face, concerning the lack of antibiotics treating the growing level of antimicrobial resistant bacteria and fungi in clinical settings. While the vast majority of microalgae and their associated microbiota remain unstudied, they may be a fascinating and rewarding source for novel and more sustainable antimicrobials and alternative molecules and compounds. In this review, we present an overview of the current knowledge on health benefits of microalgae and their associated microbiota. Finally, we describe remaining issues and limitation, and suggest several promising research potentials that should be given attention.
