Biofertilizers that possess a high capacity for N(2) fixation (Azotobacter tropicalis), and consist of phosphate solubilizing bacteria (Burkhoderia unamae), and potassium solubilizing bacteria (Bacillus subtilis) and produce auxin (KJB9/2 strain), have a high potential for growth and yield enhancement of corn and vegetables (Chinese kale). For vegetables, the addition of biofertilizer alone enhanced growth 4 times. Moreover, an enhancement of growth by 7 times was observed due to the addition of rock phosphate and K-feldspar, natural mineral fertilizers, in combination with the biofertilizer.

The article presents a study on the capacity for oil and chemical oxygen demand (COD) removal of a thermotolerant photosynthetic bacterium, Rhodobacter sphaeroides Strain, at high temperatures. After isolating Rhodobacter sphaeroides, the alginate-immobilized cells of strain NAT were used in high temperature treatment of artificial sewage wastewater containing oil. It was observed that the COD was decreased by 80% and 76% of the oil was removed after 96 hours of treatment at 55 degrees Celsius.
