Season-controlled changes in biochemical constituents viz. carotenoids (carotene and xanthophyll) and pectic substances along with IAA-oxidase and polyphenol oxidase (PPO) enzyme activities were estimated/assayed in leaves of Lycopersicon esculentum Mill. (tomato) in two developmental stages--pre-flowering (35 days after sowing) and post-flowering (75 days after sowing) in three different seaso...

Geobacillus thermodenitrificans DSM 101594 was isolated as a producer of extracellular thermostable pectic polysaccharide degrading enzymes. The completely sequenced genome was 3.6Mb in length with GC content of 48.86%. A number of genes encoding enzymatic active against the high molecular weight polysaccharides of potential biotechnological importance were identified in the genome.

background: pectic acid extracted from plants increases the secretion of prolactin (prl) when injected intravenously into ewes or fed to rats. fragments of ewe hypophysis and lactating rabbit mammary gland incubated in vitro in the presence of pectic acid secreted more prl and caseins compared to the controls. however, it is not known whether pectic acid directly stimulates prl secretion in pit...

The natural pectins are believed to consist of long, open, unbranched chains of galacturonic acid with an occasional arabinose and galactose molecule. The free carboxyl groups of the galacturonic acid are partially or wholly esterified with methyl alcohol, and an occasional hydroxyl group is esterified with acetic acid [BONNER (4), BRANFOOT (5), FREUDENBERG (7), GADDUM (8), KERTESZ (13), MYERS ...
