High cellulolytic activity of particular strains did not cause dominance of one, or a few, species of fiber-digesting bacteria in a cattlewaste anaerobic digester. The population contained a large number of species and varieties with different cellulolytic and fiber-digesting activities. Although mixed cultures of some of these bacteria showed no(More)
Two RNAi constructs were designed targeting chilli-infecting begomoviruses and associated betasatellites. Broad-spectrum resistance was achieved against multiple begomoviruses associated with leaf curl disease of chillies in India. Chilli leaf curl disease (ChiLCD) caused by begomoviruses (family: Geminiviridae) has emerged as one of the most devastating(More)
Escherichia coli O157:H7 (O157) strain 86–24, linked to a 1986 disease outbreak, displays curli- and biofilm-negative phenotypes that are correlated with the lack of Congo red (CR) binding and formation of white colonies (CR−) on a CR-containing medium. However, on a CR medium this strain produces red isolates (CR+) capable of producing curli fimbriae and(More)
A total of 794 Salmonella strains, of 26 serotypes prevalent in India, were examined for sensitivity to O-I phage. Of 597 Salm. typhi strains, 13.6% proved resistant to phage lysis. Other serotypes which contained resistant strains are Salm. anatum, Salm. paratyphi A, Salm. typhimurium, Salm. chester, Salm. colombo and Salm. matopeni. The specificity of O-I(More)
