Purification and properties of
The intracellular enzyme, L-asparaginase, from aerobically grown Erwinia aroideae NRRL B-138 has been purified and some of its properties studied. Sonic treatment permitted recovery of 95% of L-asparaginase from cells. The crude cell lysate was purified 167-fold by means of ammonium sulfate fractionation and column chromatography on hydroxylapatite ...

The Genus Hapaline (Araceae: Aroideae: Caladieae)
Kew Bulletin, 1996Hapaline is a genus of seven species occurring from Burma (Myanmar) and China (Yunnan) to Brunei. Schott (1857) published Hapale for a small, tuberous-stemmed herb collected by Wallich in Burma almost 30 years earlier. Later, Schott (1858) altered the generic spelling to Hapaline to prevent confusion with the zoological Hapale Illiger (1811), a genus ...

Characterisation of two ornithine-containing lipids from Erwina aroideae
Chemistry and Physics of Lipids, 1981Abstract An apparently pure ornithine-containing lipid (OCL) was isolated from Erwina aroideae by solvent extraction and thin-layer chromatography (TLC). However, selective hydrolysis of the lipid under acidic and basic conditions and analysis of hydrolysates by gas chromatography-mass spectrometry (GCMS) showed that two structurally similar OCL ...

chloroplast genome sequences of three Aroideae species (Araceae)
2021Colocasia gigantea, Caladium bicolor and Xanthosoma sagittifolium are three worldwide famous ornamental and/or vegetable plants in the Araceae family, These species in the subfamily Aroideae are taxonomically perplexing due to shared interspecific morphological traits and variation.

Effect of oxygen-transfer rate on production of L-asparaginase by Erwinia aroideae
Canadian Journal of Microbiology, 1973A variety of aeration and agitation conditions were used to investigate the oxygen demand of Erwinia aroideae for growth and L-asparaginase production in a 14-liter fermenter. Maximum L-asparaginase activity of 4.25 IU/ml was obtained when the fermentation medium was aerated at 0.5 volumes air per volume medium per minute and agitated at 500 rpm ...

The Response of Grape Tissue Cultures to Inoculation with Biochemical Mutants of Erwinia aroideae
Botanical Gazette, 19561. Biochemical mutants of Erwinia aroideae requiring specific amino acids were added to the surface of either intact or macerated grape tissue cultures, and their effect was noted over a period of 7 days of incubation. 2. Although all mutants eventually attacked the tissue cultures, the rate of attack differed in two respects: macerated surfaces ...

Morpho-anatomical and phytochemical diversities in selected members of family Aroideae
World Journal of Biology Pharmacy and Health SciencesMany root and tuber crops are grown throughout the world in hot and humid regions for their use as vegetable as most of them contain starch as the major carbohydrate in them. They are important diet component for human and add variety to it. Taro is used as a staple food or subsistence food by millions of people in many of the developing countries.
