Bacillus cereus and B. circulans - novel inoculants for crops

摘要

Millions of microbes inhabit the root zone of plants. Some plants are capable of exploiting these microorganisms to meet their hormonal and nutritional needs. To meet the demand for increasing productivity of economically important crop plants, several new plant–microbe asso-ciations have been reported. It has been our endeavour to isolate new rhizo-bacteria, which may enhance the yield of crop plants. Among the variety of bacteria isolated from the rhizosphere of maize (Zea mays), isolates identified as Bacillus cereus and B. circulans merit attention, since they are being reported as plant growth promoting rhizobacteria (PGPRs).
