| ABSTRACT The aim of this study was to optimize the dextranase production by fungus Pochonia chlamydosporia (VC4) and evaluate its activity in dextran reduction in sugarcane juice. The effects, over the P. chlamydosporia dextranase production, of different components from the culture medium were analyzed by Plackett-Burman design and central composite design. The response surface was utilized to determine the levels that, among the variables that influence dextranase production, provide higher production of these enzymes. The enzymatic effect on the removal of dextran present in sugarcane juice was also evaluated. It was observed that only NaNO3 and pH showed significant effect (p<0.05) over dextranase production and was determined that the levels which... |

| Abstract: The objective of this work was to evaluate the stalk yield, technological quality parameters, and sugar and alcohol productions in the first sugarcane (Saccharum officinarum) crop cycle, according to the response to N and K2O applications by subsurface drip fertigation. The experiment was carried out in a dystrophic Ultisol, in a randomized complete block design with four replicates. The treatments consisted of a 2X + 2X + 1 incomplete factorial arrangement with the application of 60, 80, 120, 160, and 180 kg ha-1 N and 60, 80, 120, 160, and 180 kg ha-1 K2O. The maximum estimated yield (217.5 Mg ha-1) was obtained with the application of 180 kg ha-1 N and 60 kg ha-1 K2O. Sugar and alcohol productions increased with N application above 120 kg... |
