A new 14-membered cembrane-type diterpenoid, jatrophainolide D (1), along with six known compounds, (E)-phytol (2), lupeol (3), stigmasterol (4), ergosta-4,6,8 (14),22-tetraen-3-one (5), stigmast-4-ene-3-one (6), and ergosterol peroxide (7) were isolated from the aerial parts of Jatropha integerrima. The structure isolates was elucidated by IR, UV, 1D-/2D-NMR, HRESI-TOFMS data as well comparison reported spectroscopic data. All evaluated antibacterial activity against S. enterica, E. coli,...
Experimental results proved that the development of Colletotrichum capsici B4 is extremely sensitive to water-soluble chitosan (WSC) and inhibitory effects increase with increasing concentrations WSC. In in vitro test, showed entire prevention conidial germination mycelial diameter are recognized a potato dextrose agar medium containing 0.4% 0.8% WSC, respectively. WSC was more efficient broth where it absolutely prevented C. at concentration 0.32%. treatments considerably decreased disease...
Effect of water-soluble chitosan (WSC) on green mould disease caused by Penicillium digitatum P4 was investigated in vitro and vivo. Results the experiments showed that P. growth much inhibited WSC inhibitory effect increased as concentration increased. In test results indicated complete inhibition spore germination mycelial were observed medium containing 1 mg/ml WSC. vivo study, treatments significantly reduced incidence lesion diameter orange fruits. After 8 days inoculation, fruits...
Water-soluble chitosan, the product of chitosan hydrolysis with particular biological characteristics, has been used in fields food storage and plant protection. Hydrogen peroxide was to optimally degrade crude into water-soluble (WSC). The mathematical model between independent factors (H2O2 level, time temperature) recovery WSC constructed optimize degradation conditions using response surface methodology. optimal for highest were 5.4% H2O2, 47.1°C 3.4 h, predicted 87.2%. fungal strain...
Nghiên cứu này được thực hiện nhằm đánh giá ảnh hưởng của màng bọc nanochitosan với các nồng độ khác nhau đến chất lượng trứng gà tươi dựa vào biến đổi cảm quan và bên trong 30 ngày ở nhiệt thường. Mẫu 0,4% có khả năng duy trì hạng mức A 15 sau khi đẻ. Trong đó, mẫu không rất nhanh từ AA xuống B chỉ 5 bảo quản Đồng thời tiêu (HHKL, HU, YI, pH lòng trắng, hàm NH3 trứng) đều lớn hơn so xử lý Kết quả nghiên đã chứng tỏ bao kéo dài gian tươi.
Nghiên cứu này nhằm xác định ảnh hưởng của một số yếu tố (nhiệt độ, pH ban đầu, thời gian nuôi cấy, nồng độ CMC, NaNO3) đến khả năng sinh tổng hợp cellulose chủng nấm mốc Aspergillus niger T2 và ứng dụng trong quá trình chế biến tiêu sọ. Kết quả cho thấy các điều kiện thích để cellulase cao nhất ở nhiệt 30oC, đầu là 4,5, cơ chất CMC: 1,5% NaNO3: 0,3% sau 144 giờ cấy với giá trị hoạt enzyme thu được lần lượt 328,649 IU/ml, 459,323 UI/ml, 466,447 466,762 UI/ml 287,594 UI/ml. Sinh khối ủ...
