To the pellet, 4 ml of 5% sorbitol was added, mixed gently and incubated for 15min at 37°C. The mix was shaken 2 or 3 times and centrifuged at 200g followed by washing 3 times in complete medium (list I). The culture was then maintained at 5% hematocrit in a 37°C incubator

    1. The procedure of Hagerman and Butler (1978) was used to estimate the tannin content in different tannin sources. Reagents: Bovine serum albumin (BSA) 1.0 mg/ml: 10.0 mg of bovine serum albumin was dissolved in 10.0 ml of 0.2 M acetate buffer, pH 5.0, containing 0.17 M sodium chloride. Sodium dodecyl sulfate (SDS)-triethanolamine solution: The solution contained 1.0% SDS and 5.0% (v/v) triethanolamine in distilled water. Ferric chloride reagent (0.01 M): 1.62 g of ferric chloride was dissolved in 1.0 L of 0.01 N hydrochloric acid.
