Their supernatants for control

IJs released from infected larvae would have the potential to infect healthy mosquito larvae. Also, both bacterial supernatant and bacterial cell suspension of Xenorhabdus nematophila caused >91% larval mortality after 48 h, whereas only the bacterial cell suspension of Photorhabdus laumondii was effective against the mosquito larvae. These data provides useful information on the potential use of EPNs and/or formulated bacterial cell suspensions in the control of the important urban and container-breeding mosquito, Ae.

Charcoal rot of sorghum caused by Macrophomina phaseolina is a disease of economic importance for which a high level of genetic resistance is not available. Therefore, an effort was made to manage this disease with potent rhizobacterial strains viz., AUDP 139 and AUDT 801 in CSV 8R and CSV 29R cultivars. In CSV 8R, seed soaked in supernatants of AUDP 139 for two hours recorded least charcoal rot incidence of 40.58 % with highest yield of 1924.90 Kg/ha whereas in CSV 29R, seed treatment with AUDT 801 + AUDP 139 @ 3g/Kg of seeds recorded least disease incidence of 14.

The Clostridium difficile toxins, toxin A and Toxin B were characterised in respect to the influence of glucose and incubation period on release of toxins, cytotoxic activities of the toxins in Verocell line and the immunogenic potential of C. difficile toxoids. A gradual increase in protein concentrations was observed in the cell free supernatants of toxin A and B positive C. difficile isolate with increase in incubation period and found to reach the highest at 48 hr of incubation, i.e., 5.24 µg/µl and 5.06 µg/µl, respectively. Release of C.
