“…Isolated peptides from Chinese lima beans ( Phaseolus lunatus L.) were found effective against various bacteria (e.g. Bacillus megaterium , B. subtilis , Proteus vulgaris , and Mycobacterium phlei ), whereas defensins obtained from Vigna unguiculata seeds showed defensive properties against E. coli . According to Godlewska et al ., aqueous extracts obtained after boiling of Baltic seaweeds ( Polysiphonia , Ulva , and Cladophora ) showed significant in vitro inhibitory effects against E. coli but did not affect S. aureus cultures.…”

“…Bacillus megaterium, B. subtilis, Proteus vulgaris, and Mycobacterium phlei), whereas defensins obtained from Vigna unguiculata seeds showed defensive properties against E. coli. 39 According to Godlewska et al, 40 aqueous extracts obtained after boiling of Baltic seaweeds (Polysiphonia, Ulva, and Cladophora) showed significant in vitro inhibitory effects against E. coli but did not affect S. aureus cultures. Moreover, Gan et al 41 suggested that pigmented seed coats of various legumes may be used as natural food preservatives and the high antibacterial efficacy was positively correlated with flavonoids and proanthocyanidins content.…”

“…Khi mọt ăn hạt đậu xanh, defensin đã ức chế hoạt động của α-amylase, do đó ngăn chặn sự tiêu hóa tinh bột, kìm hãm sự sinh trưởng, phát triển và dần mọt sẽ chết Liu et al, 2006). Trong những năm gần đây đã có một số nghiên cứu về cấu trúc và hoạt tính sinh học của defensin thực vật, đề xuất ứng dụng trong công nghệ sinh học trong nghiên cứu chức năng của gen defensin và nâng cao khả năng kháng mọt ở cây đậu xanh (Cavalho et al, 2009(Cavalho et al, , 2011Dos et al, 2010;Tavars et al, 2008).…”

“…seeds The extraction and purification of antimicrobial peptides from Brassica juncea seeds (Sakata Seed Corporation, Yokohama, Japan) were performed as described by Dos Santos et al 10) with some modifications. B. juncea seed flour (100 g) was soaked for 1 hr with a 400 mL extraction buffer (10 mM Na 2 HPO 4 , 15 mM NaH 2 PO 4 , 100 mM KCl, and 2 mM EDTA) added with 4 protease-inhibitor cocktail tablets (Roche Diagnostics, Tokyo, Japan) at 4°C.…”
