Palynology of the perigoniate Aroideae: Zamioculcas, Gonatopus and Stylochaeton (Araceae) [PDF]

open access: yesGrana, 2001
The pollen of the perigoniate Aroideae sensu Mayo et al. (1997) ( Zamioculcas Schott, Gonatopus Hook. f. ex Engl. and Stylochaeton Lepr.) differs ultrastructurally from that of the aperigoniate Aroideae in several important exine and aperture characters.

A Study on L‐Asparaginase of Nocardia levis MK‐VL_113

open access: yesThe Scientific World Journal, Volume 2012, Issue 1, 2012., 2012
An enzyme‐based drug, L‐asparaginase, was produced by Nocardia levis MK‐VL_113 isolated from laterite soils of Guntur region. Cultural parameters affecting the production of L‐asparaginase by the strain were optimized. Maximal yields of L‐asparaginase were recorded from 3‐day‐old culture grown in modified asparagine‐glycerol salts broth with initial pH

Recognition of the genus Thaumatophyllum Schott − formerly Philodendron subg. Meconostigma (Araceae) − based on molecular and morphological evidence [PDF]

open access: yes, 2018
Philodendron subgenus Meconostigma has been a well-circumscribed group since 1829. Members of this group are easily distinguished by diagnostic morphological characters as well as by a distinct ecology and geographical distribution.

Enzymatic synthesis of phenoxymethylpenicillin using Erwinia aroideae enzyme.

open access: yesThe Journal of Antibiotics, 1984
Enzymatic synthesis of phenoxymethylpenicillin from 6-aminopenicillanic acid and phenoxyacetic acid methyl ester was attempted by using partially purified alpha-acylamino-beta-lactam acylhydrolase I (ALAHase I) enzyme from Erwinia aroideae NRRL B-138.
