In a search for microorganisms antagonistic to bacteria, especially to the gram-negative ones, the bacterial-agar plate method was used (Waksman and Woodruff, 1940a). This consists in adding a suspension of washed living bacteria to 1.5 per cent sterile washed agar containing 0.5 per cent NaCl and 0.5 per cent K2HPO4. To a fresh field or garden soil, or one previously enriched several times wit...

The world potato is facing major economic losses due to disease pressure and environmental concerns regarding pesticides use. This work aims at addressing these two issues by isolating indigenous bacteria that can be integrated into pest management strategies. More than 2,800 strains of Bacillus-like and Pseudomonas-like were isolated from several soils and substrates associated with potato agr...

In an attempt to screen out new potent antimicrobial substances producing bacteria, Corynebacterium kutscheri NB-1 and Corynebacterium xerosis NB-2 were isolated and were found antagonistic to bacteria and fungi. Antimicrobial substances production of the bacterial strains was greatly influenced by variation of carbon sources. Galactose and glucose strongly enhanced the antimicrobial activity o...

This study was designed to isolate oral bacteria exhibiting antagonism towards Treponema denticola and to characterize the inhibitory activity. Eleven bacterial isolates obtained from subgingival sites and identified as either Staphylococcus aureus or Streptococcus mutans were found to inhibit the growth of T. denticola. When the activity spectra of these isolates were analyzed, two additional ...

The present investigation was carried out to isolate and characterize antagonistic bacteria against wilt causing fungal pathogen i.e. Fusarium oxysporum, from the rhizosphere of tomato. Fifty-six bacterial strains were isolated from the rhizosphere soil samples of healthy tomato fields, collected from different locations of Faridabad district, Haryana, India. Out of these, ten isolates were fou...
