Production of beta-1,3 glucan from Agrobacterium and its wound healing activity on white rat. The objective of this study was to determine the activity of beta-1,3 glucan product extracted from local Agrobacterium sp Bro 1.2.1, both wild-type and mutant-type, on opened-wound healing process. Beta-1,3 glucan product was extracted by precipitation, and the purification was carried out by column chromatography as KCl gradient fractions. In this study, white Sprague Dawley rats were employed, and have been treated for opened-wound condition. Seven groups were performed in this experiment, i.e. the negative control, the positive control employing povidone iodine, the two groups of two commercial beta-1,3 glucan with 0,02 mg/4 cm2 each, and the last three groups of beta-1,3 glucan as the test group with 0,02 mg/4 cm2, 0,10 mg/4 cm2 and 0,50 mg/4 cm2, respectively. The result showed significant differences of wound-healing activity performing statistical analysis of the least significance between the negative control, the positive control, as well as the highest dose of the test group of beta-1,3 glucan, at the dose of 0,5 mg/4 cm2 (p<0.05).

Influence of Uracil in Fermentation Media on β-Glucan Production by Agrobacterium Radiobacter A 1.5 and Agrobacterium sp. Bro 1.2.1. Optimum β-glucan production can be achieved by an optimum condition in the fermentation media. Uracil, as a precursor of UDP-glucose, may act as a glucose donor in the formation of polysaccharides such as β-glucan. It is expected that addition of certain quantity of uracil into the fermentation media in a suitable growth phase of Agrobacterium radiobacter A 1.5 and Agrobacterium sp. Bro 1.2.1, will significantly increase the β-glucan production. In this investigation, 0.025%; 0.05% or 0.1% of uracil were added into the fermentation media during the logarithmic phase (24 hour) or stationary phase (46 hour) of growth. The β-glucan product was evaluated from the β-glucan (crude) dry-weight and from the β-glucan content. Beta-glucan content was determined as glucose by the Hisamatsu-AOAC and HPLC methods. The highest β-glucan (crude) dry-weight produced by the A. 1.5 was in a medium containg 0.025% uracil (24 hour), whilst by the A. Bro 1.2.1 was in a medium containg 0.1% uracil (46 hour), both higher than control. The highest β-glucan content produced by the A. 1.5 (27.03%) was in a medium containg 0.025% uracil (46 hour), while control produced only 23.28%. The highest β-glucan content produced by the Bro 1.2.1 (29.34%) was in a medium containg 0.025% uracil (24 hour), while control produced only 28.75%. Two-way anova analysis showed that there were no significant influence difference (α = 0,05) from various concentration of uracil in either growth phases, to the yield of β-glucan (crude) dry-weight nor to the β-glucan equivalent glucose content.
