Bioconversion of wastewater from sweet potato starch production to Paenibacillus polymyxa biofertilizer for tea plants

Wastewater from the sweet potato starch industry is a large source of nutrient-rich substrates. We assessed whether this wastewater could be used to produce Paenibacillus polymyxa biofertilizer for foliar application to tea trees. Using the central composite design methods we experientially determined that the optimal culture conditions for P. polymyxa were pH, 6.5; temperature, 29.0 °C; and in...

Utilization of Sweat Potato Starch Wastewater and Monosodium Glutamate Wastewater for Cultivation of an Anti-Fungal Biocontrol Agent Paenibacillus Polymyxa

Effluents from monosodium glutamate manufacturing plants possess a high strength of COD (10,000--30,000 mg/l), ammonium (15,000--25,000 mg/l), sulphate (15,000--30,000 mg/l) and very low pH (< 2) (Yang et al., 2005). Effluents from sweat potato starch industry contains a high load of protein, pectin, and starchy materials with the COD of 10,000 35,000 mg/l (Mishra et al., 2004). Due to the low ...

Cytokinin production by Paenibacillus polymyxa

The production of hormones has been suggested to be one of the mechanisms by which plant growth-promoting rhizobacteria (PGPR) stimulate plant growth. To evaluate whether the free-living soil bacterium, Paenibacillus polymyxa, releases the hormone group cytokinins and, if so, their identity, the content of cytokinins in the growth media, before and after cultivation of this bacterium, was deter...

Biofertilizer production from gas refinery wastewater

Abstract In this study the wastewater treatment of a gas refinery was investigated by using an aerobic trickle bed filter bioreactor. Using a methanothrophic bacterium was the only difference of this experiment from the common aerobic wastewater treatment processes. In addition to reach the standards of wastewater treatments the other goal of using this special bacterium was the productio...

Starch phosphorylase inhibitor from sweet potato.

A protein, starch phosphorylase inhibitor, was purified from the root of sweet potato (Ipomoea batatas [L.] Lam. cv Tainon 65). It had a molecular weight of 250,000 and could be composed of five identical subunits. The isoelectric point of the inhibitor was 4.63. It was a noncompetitive inhibitor toward the sweet potato enzyme with a K(i) value of 1.3 x 10(-6) molar when glucose-1-P was the var...
