Microwave-assisted extraction of pectin from lemon peels by using ionic liquid as alternative solvent was investigated. The extracted pectin was detected by Fourier transform infrared spectra. The extraction conditions were optimized through the different experiments in conjunction with the response surface methodology. A pectin yield of 24.68 % was(More)
Newly isolated strains ofPhytophthora infestans belonging to the same physiological race differ in their rate of spread and depth of penetration on tubers and in their rate of growth on three synthetic media. They also differ in their speed of sporulation on leaves. Their growth on tubers is in general faster on the variety from which the strains were(More)
