Four diazinon-degrading bacteria were isolated from agricultural soil by using an enrichment technique. The biochemical analysis and molecular method including RFLP indicated that these isolates were identical, and one strain designated DI101 was selected for further study. Phylogenetic analysis based on 16S rDNA sequencing indicated that the strain DI101 clearly belongs to the Serratia marcesc...

Hunt et al. (2) and Norton (4) showed that the northern root-knot nematode, Meloidogyne hap/a Chitwood, increased the incidence of bacterial wilt in alfalfa. Hunt et al. (2) also f o u n d t h e b a c t e r i a l wilt organism, Corynebacterium insidiosum (McCuU) H. L. Jens., in plant tissue that had been inoculated only with the bacteria. This would indicate that the role of M. hapla is somethi...

Using cotyledons of 2-week old in vitro germinated seedlings, a rapid and efficient regeneration protocol was established for A. mangium on Murashige and Skoog (MS) basal medium. Cotyledons showed better direct shoot organogenesis producing maximum 10.88 ± 0.35 shoots per explant when cultured on MS medium supplemented with 2.0 μM BA and 1.0 μM NAA. Full strength of MS medium supplemented with ...

To this day there is still no definitive model for the evolutionary emergence of eukaryotic cells. Before WWII, there existed two non-Darwinian models that have now been forgotten the symbiotic and the orgonomic theories, which are contrasted in the present review. Both had in common the notion that the eukaryotic cell was simply a spontaneous assemblage of prokaryote-like vesicles. The orgonom...

Growth of the organisms. Nitrobacter was obtained from an Aberdeen garden soil by serial subculture in a medium made up as follows. To 10 1. ofwater were added 30 g. ofKH2P04, 1 g. of CaSO4, 0 5 g. of MgCl2, 0 01 g. of MnCl2, 0-2 ml. of dialysed iron (B.P.). By addition of lOM-NaOH, the pH was adjusted to 7-8, which is the optimum pH for the strain of Nitrobacter used (Lees, 1954). The solution...

Present study compared, for the first time, impact of processing (soaking, cooking and sterilization) storage conditions (in terms time (0–40 weeks), temperature (20–42 °C), oxygen availability) on headspace volatile profile chickpeas. Soaked chickpeas contained more aldehydes alcohols associated with unpleasant “beany” aromas compared to intensively processed (i.e., sterilized) chickpeas, whic...

A bench-scale biotrickling filter was operated in the laboratory for the treatment of dimethyl sulphide (DMS). The biotrickling filter was packed with pre-sterilized polyurethane foam and seeded with biomass developed from garden soil enriched with DMS. The biotrickling filter was operated for the generation of process parameters. The biotrickling filter could remove an average removal efficien...

BACKGROUND Jatropha curcas L. (Jatropha) is a potential biodiesel crop that can be cultivated on marginal land because of its strong tolerance to drought and low soil nutrient content. However, seed yield remains low. To enhance the commercial viability and green index of Jatropha biofuel, a systemic and coordinated approach must be adopted to improve seed oil and biomass productivity. Here, we...
