“…The studies tested the antibiotic effect of the ethanol, chloroform, petroleum ether, methanol, and acetone extracts from Spirogyra spp. against several bacteria like P. solanacearum, E. coli, and C. michiganens, showed a highly significant antibiotic activity against P. solanacearum (Naik et al, 2012;Dwaish et al, 2016;Daniel et al, 2019). Similarly, this study demonstrated a high zone of inhibition (19 mm) against Gram-positive S. aureus when the ethanol extract (Usharani et al, 2015).…”

In the recent past, the importance of freshwater algae has grown enormously due to their antibiotic activity against certain species of bacteria known for several disease states like endocarditis, external otitis, skin rash, etc. Also, there is a growing concern among the immunocompromised individuals that they may be susceptible to antibiotics and anti-fungal resistant infections resulting in increased fatality rates. Hence, in this investigation, extraction of potentially bioactive compounds from natural resources like freshwater algae was performed along with the evaluation of the antimicrobial activities of these extracts against some opportunistic bacteria like Staphylococcus aureus, Escherichia coli, Staphylococcus xylosus and Pseudomonas aeruginosa using well diffusion method. The data showed a statistically significant (P < 0.05) antibacterial activity of the organic extracts (0.1 g/ml) obtained from freshwater algae against multi-drug resistant S. aureus and S. xylosus strains as compared to the control. Our data reinforce the importance of bioactive compounds from fresh algae as potential antimicrobial agents, and they could act as an alternative to conventional antibiotics.

“…Previous studies by Dwaish et al 2016;Syamsuddin et al 2016;Uthorn et al (2019) This observation is consistent with a prior study indicating that Spirogyra rhizopus, extracted using various solvents such as ethanol, methanol, chloroform, and acetone, exhibited substantial inhibitory efficacy against S. typhimurium, P. aeruginosa, S. aureus and E. coli. (Daniel et al 2019). Methanol extracts demonstrated the highest zone of inhibition against all strains except for S. lutrae, S. lugdunensis and E. coli, where ethanol had the most potent inhibitory effect.…”

“…It has been reported that both Hexadecanoic acid and Octadecadienoic acid demonstrate antibacterial activity, inhibiting Grampositive and Gram-negative bacteria to some extent. (Kumar et al 2015;Dwaish et al 2016;Okunowo et al 2017;Daniel et al 2019). Hence, it can be inferred that Phytol 9,12-Octadecadienoic acid ethyl ester and Hexadecanoic acid possess potent antimicrobial properties.…”

Mastitis is an inflammation of the mammary gland that significantly threatens dairy productivity. With the emergence of antibiotic-resistant pathogens, it has become necessary to find alternative antimicrobial agents. Spirogyra neglecta, a filamentous green alga, is known for its diverse bioactive compounds. This study uses various solvents to investigate the antimicrobial potential of S. neglecta extracts against mastitis-inducing pathogens. The results show that methanol extract has the highest efficacy in inhibiting bacterial growth, with minimum inhibitory concentration (MIC) values ranging from 8.75-200mg/mL. These findings highlight the promising antimicrobial capabilities of S. neglecta and its potential as a natural agent in combatting mastitis-inducing pathogens. This research paves the way for further exploration and utilization of S. neglecta in veterinary and pharmaceutical applications.

A number of advancements have been made in algal technology in different fields, such as medical, cosmetic, and pharmaceutical. Green algae (Chlorophyta) are a group of photosynthetic organisms which live in both aquatic and terrestrial environments. They are a potential source of bioactive compounds for the treatment and prevention of a wide range of infectious diseases caused by microorganisms. These compounds also possess anti-inflammatory, antioxidant, anticoagulant, antitumor, and immunomodulatory properties. A wide variety of bioactive compounds are produced, including polysaccharides, which exhibit antimicrobial properties capable of interfering with the cell walls, membranes, and nucleic acids of microorganisms. Membrane fluidity, permeability, or integrity can be affected by polyphenols and fatty acids which scavenge free radicals, chelate metal ions, or disrupt enzymes and membranes. Proteins and peptides form pores within the membranes which bind to specific receptors or inhibit enzymes. Adaptation to adverse environmental conditions, such as temperature extremes, photooxidation, salinity, or osmotic stress, results in the formation of bioactive compounds by altering the physiological and biochemical pathways of algae for the maintenance of cellular homeostasis. With changing consumer preferences and an increase in the number of resistant microorganisms, it is critical to seek novel antimicrobial compounds from green algae. The search for novel bioactive compounds with antimicrobial properties from green algae may serve as an alternative in the light of increased drug resistance in microorganisms. However, in vitro and in vivo evaluations of the safety, efficacy, and mechanism of action of the antimicrobial compounds from green algae require more research. Providing an overview of previous endeavours in this emerging field, this review provides perspectives and a summary of the bioactive compounds responsible for the antimicrobial properties of green algal extracts.
