The methylotrophic yeast Candida boidinii S2 was found to be able to grow on pectin or polygalacturonate as a carbon source. When cells were grown on 1% (wt/vol) pectin, C. boidinii exhibited induced levels of the pectin-depolymerizing enzymes pectin methylesterase (208 mU/mg of protein), pectin lyase (673 mU/mg), pectate lyase (673 mU/mg), and polygalacturonase (3.45 U/mg) and two methanol-met...

Jute, Corchorus capsularis, is the most important cash crop of Pakistan. Most of the foreign exchange earned comes from the export of jute. For this reason jute is popularly called the "golden fiber" of Pakistan. A very importanit step in the jute industry is retting. During this process, some microorganisms decompose pectins of jute bark and the intervening tissues disintegrate. The pectins ar...

rhe cuiticle of plants is a heterogenous memnbranie in which wax, pectin and cellulose in varying l)ro)ortions are contained in a cutin franmework. In the isolation of cuticular membranes from leaves or fruits the wax is nornially removed by extraction xvith ani organic solvent before detachment of the memnbranes from the underlying epidermal cells. Detachnmenit is achieve(d by the use of eithe...

In peach (Prunus persica L. Batsch.) the degradation of the pectic compounds of the cell wall is considered to be the principal component responsible for fruit softening. Many genes encoding enzymes acting on the different polymers of the pectic matrix have been shown to be highly expressed during the late phases of softening, with polygalacturonase being the most important. Nevertheless, it is...

One hundred and three Aspergillus isolates belonging to 12 species including: A. alliaceus, A. candidus, A. carneus, A. flavus, A. fumigatus, A. niger var. niger, A. niger var. awamori, A. niveus, A. ochraceous, A. sydowii, A. terreus, A. ustus,and A. versicolor based on morphological characters were obtained from various sources. 

RNA-Seq analysis has shown that over 60% (12,962) of the predicted transcripts in the Phytophthora parasitica genome are expressed during the first 60 h of lupin root infection. The infection transcriptomes included 278 of the 431 genes encoding P. parasitica cell wall degrading enzymes. The transcriptome data provide strong evidence of global transcriptional cascades of genes whose encoded pro...

Many plants and plant materials such as wood (2), tea (25), tobacco (15), cotton (16), hops (13), ramie (11), flax (12), grass (6), potato (10), plantain seed (20), celery (9), limes (22), guava (1), bergamnot (23), and root hairs (21), have been shown to contain pectic compounds. Because different methods of extraction and analysis were employed, it is impossible to iiiake comparative studies ...

Pectinases are a group of enzymes with broad application, including in plant fiber processing, pectic wastewater treatment, paper pulping, fruit juice extraction, and clarification. With an increasing industrial demand for these enzymes, it is useful to isolate organisms that produce large amounts pectinase possess wide ranges stability factors like temperature pH. In this study, 17 out 29 bact...

Vegetable proteins such as soybean meal, canola meal and lupins are widely used as the main protein source in poultry diets. However, there is only limited information on the nutritive or anti–nutritive effects of indigestible non–starch polysaccharides in vegetable proteins. This review discusses a number of experiments which investigated the effects of feed enzymes on the utilisation of non–s...
