Abstract
Abstract The optimization study of gluconic acid fermentation was carried out using Aspergillus niger at three different carbon sources. The experimental study was conducted with different glucose concentration, pH, temperature, age of culture, agitation and volume of inoculums with a continuous shaking flask method. Gluconic acid production was affected by increase of carbon concentrations at the same time fermentation time also increased. The siginificant level of gluconic acid (148 g/L) production was observed at 96 hrs with maximum 84% of glucose conversion. The gluconic acid yield/gram of glucose feeding was 74%. The isolated fungus has the capacity to produce maximum amount of gluconic acid.

The differences recorded in mean values due to varieties for plant height were observed as non– significant and the values were in the range of 57.9 for Puhja to 58.7 for Nutech
The data revealed that the range of mean values for radiation doses was 31.6 to 44.5 for the number of leaves per plant .The differences recorded in mean values due to varieties for number of leaves per plant were observed as significant and values were in the range of 34.5 for Nutech and 41.4 for Puhja
Summary
Okra (Abelmoschus esculentus L.) is one of the most important vegetable crops grown for its green tender fruit Okra is a flowering plant. It is called lady’s finger or gumbo. It is an annual or perennial species, grows to about the height of 2 m. Okra is more popular in southern part of the United States. The other half is insoluble fiber which helps to keep the intestinal tract healthy and reducing the risk of some forms of cancer, especially colorectal cancer
