Abstract

Eighteen fungal species were isolated from rhizospheric soil and rhizoplane samples of three plant crops in southern Iraq. The fungal isolates were examined for the activities of four enzymes (amylase, cellulase, phenoloxidase, and protease), as well as their growth, against crude garlic extract added to the culture agar medium. A high reduction or inhibition of enzymatic activities was observed for the fungi treated with garlic extract compared with untreated fungal cultures. However, most of the species showed inhibition of enzymes due to the effect of garlic extract. The growth of the fungal species was also remarkably reduced by the garlic extract.

Co-Amended Synergistic Interactions between Arbuscular Mycorrhizal Fungi and the Organic Substrate-Induced Cucumber Yield and Fruit Quality Associated with the Regulation of the AM-Fungal Community Structure under Anthropogenic Cultivated Soil

“…We found a co-inoculation antagonistic relationship with a cucumber root pathogen (Fusarium infection) with the AM-inoculum + GS-substrate treatments, and the observed reduction, due to the strength of the applied dual inoculants responded with a more effective induction of rooting structure, increases in root activity, and thus, a pronounced influence on the fruit quality attributes (Table 6, Tables S2 and S3). The pragmatic bio-efficacy of this study could plausibly explain that garlic or garlic-derived potent compounds (flavonoids, sulfur-containing compounds, phenolic, carbohydrates, and antioxidants enzymes) have not only been recognized as bio stimulants [48,49,51] but have also been reported to be strong antimicrobial agents [52,53,54].…”

Garlic, from Remedy to Stimulant: Evaluation of Antifungal Potential Reveals Diversity in Phytoalexin Allicin Content among Garlic Cultivars; Allicin Containing Aqueous Garlic Extracts Trigger Antioxidants in Cucumber

“…Most of fungi use various cell wall degrading enzymes to penetrate into the host cellular compartments (Tonukari, 2003) and if these enzymes are restrained or disrupted, the ability to penetrate into and consequently colonize inside host body is impaired. Muhsin et al (2001) reported that garlic bulb extracts significantly inhibited production of cell wall degrading enzymes in various fungi. A variety of organosulfur compounds such as DADS, DATS, Ajoenes etc., may contribute to the biological activity of garlic derived compounds (Avato et al, 2000; Rahman and Lowe, 2006; Yun et al, 2014).…”

Effect of aqueous and organic solvent extraction on in-vitro antimicrobial activity of two varieties of fresh ginger (Zingiber officinale) and garlic (Allium sativum)

“…This is in line with previous studies that investigated antifungal activity of garlic against C. albicans ( Suleiman and Abdallah, 2014 ). High inhibition to fungi is attributed to the activity of allicin which is known to curb the performance of some enzymes that is important to fungal growth and activity ( Muhsin et al., 2001 ).…”
