Antimicrobial activity of broccoli (Brassica oleracea var. italica ) cultivar Avenger against pathogenic bacteria, phytopathogenic filamentous fungi and yeast

Abstract

Broccoli's crude extracts have activity not only against pathogenic bacteria but also against phytophatogenic fungi of importance in agriculture. We suggest for first time that the inhibitory effect is probably due to AMPs.

Bioactive Compounds and Bioactivities of Brassica oleracea L. var. Italica Sprouts and Microgreens: An Updated Overview from a Nutraceutical Perspective

“…With the diversity in the molecular structure and chemical composition, these compounds can perform distinct antimicrobial effects, such as destabilization of the plasma membrane or inhibition of extracellular enzymes [110]. The antimicrobial activity against pathogenic bacteria, yeast, and phytopathogenic fungi was also proven by the presence of many antimicrobial peptides in broccoli floret extract [111].…”

Phytochemical characterization, and antioxidant and antimicrobial activities of white cabbage extract on the quality and shelf life of raw beef during refrigerated storage

“…The antimicrobial activity of the extract may be attributed to the presence of avonoid and phenolic content, which have been reported to be involved in antibacterial and antifungal activity of plant extracts. 10,21,23,24 Further, the chloroform extract of WC was heated at 95 C for three different times (5, 45, and 90 min) to evaluate the thermostability of the extract. The bioactive compounds present in WCCE showed heat stability and the antimicrobial activity enhanced with an increase in heating time ( Table 2).…”

“…7,8 In this regard, various plants have been investigated scientically as antimicrobial and antioxidants in foodstuff. [9][10][11] In addition, these plant extracts considered nutritionally safe and easily degradable. 8 At present, vegetables attain substantial importance among the possible added natural antimicrobials and antioxidants due to the presence of a wide range of plant secondary metabolites such as phytochemicals that have been used for centuries in ancient or traditional medicine.…”

Polyphenolic Profile and Varied Bioactivities of Processed Taiwanese Grown Broccoli: A Comparative Study of Edible and Non-Edible Parts

“…Plant phenolics and extracts rich in such substances could inhibit the growth of various bacterial pathogens [33]. Over the last years, the detrimental effect on microorganisms was extensively studied on broccoli florets [34][35][36][37]. For instance, the antimicrobial activity of broccoli florets was evaluated using flow cytometry to identify dead cells probably owing to cell disruption and effusion of internal contents [36].…”
