Rhizobium pongamiae sp. nov. from Root Nodules of Pongamia pinnata
Pongamia pinnata has an added advantage of N2-fixing ability and tolerance to stress conditions as compared with other biodiesel crops. It harbours "rhizobia" as an endophytic bacterial community on its root nodules. A gram-negative, nonmotile, fast-growing, rod-shaped, bacterial strain VKLR-01(T) was isolated from root nodules of Pongamia that grew optimal at 28°C, pH 7.0 in presence of 2% NaC...
متن کاملPrenylated Flavonoids from Pongamia pinnata
Pongamia pinnata (Leguminosae) is widely distributed along southeastern Asia to the west Pacific and north Australia. All parts of the plant have been used as crude drug for the treatment of tumors, piles, skin diseases, wounds, ulcers, etc. [1]. Extracts of the plant possess significant anti-diarrhoeal, anti-fungal, anti-plasmodial, anti-ulcerogenic, anti-inflammatory, analgesic activities [2 ...
متن کاملBiofibres from biofuel industrial byproduct—Pongamia pinnata seed hull
BACKGROUND Biodiesel production using Pongamia pinnata (P. pinnata) seeds results in large amount of unused seed hull. These seed hulls serve as a potential source for cellulose fibres which can be exploited as reinforcement in composites. METHODS These seed hulls were processed using chlorination and alkaline extraction process in order to isolate cellulose fibres. Scanning electron microsco...
متن کاملPhytohemical Screening and Gut Motility Activity of Pongamia Pinnata Bark in Experimental Animal Models
The present study was carried out with the bark of Pongamia pinnata Linn, belonging to the family Fabaceae. It is one of the fast growing, glabrous, deciduous tree and has recently gained importance as a commercial source of furanoflavones like kaempferol, karanjin. Methanolic extract of Pongamia pinnata was subjected to phytochemical screening. Gut motility activity was produced by oral admini...
متن کاملPreparation of biodiesel from crude oil of Pongamia pinnata.
Biodiesel was prepared from the non-edible oil of Pongamia pinnata by transesterification of the crude oil with methanol in the presence of KOH as catalyst. A maximum conversion of 92% (oil to ester) was achieved using a 1:10 molar ratio of oil to methanol at 60 degrees C. Tetrahydrofuran (THF), when used as a co-solvent increased the conversion to 95%. Solid acid catalysts viz. Hbeta-Zeolite, ...
