Abstract : Microbial and chemical extraction of pectin from some agro-industrial wastes (grapefruit, orange fruit, mango fruit, lemon fruit and onion scales) proved that grapefruit waste (GFW) contains more amounts of pectin than the other wastes. GFW contains about 37.5% pectin, 17.2% soluble sugars, and 14.3% holocellulose of its dry weight. The highest bioextraction of GFW pectin by Kluyveromyces marxianus (35.6%), extracellular protein(5.5%) and protopectinase activity(12.02µ/ml), as well as, yeast gowth (342x108cfu/ml) were obtained under the following optimized fermentation conditions: absence of yeast extract, 0.4% peptone, 1.0% glucose and 8 % grapefruit waste (added at zero time of incubation), under shaked conditions (200 shakes/min) for 18h at 30°C, pH 5 and seed culture of 24h (old) at 4 % level
