It had been found to be negative for indole test (no blue color), citrate test, methyl red Voges-Proskeur test (no red color), casein hydrolysis test (no clear zone) and for starch agar test.
BRR 3a (Lactobacillus sp.) identified on the basis of biochemical tests had antibacterial activity of 1.8 mm and found to be negative for catalase test (no bubble formation), indole test (green layer formed in test tube), citrate test (green forest colour in test tube), methyl red Voges-Proskeur test (Fig.
The results obtained by using conventional biochemical test confirmed the significant difficulties for Klebsiella differentiation at the species level, even when reference strains were included and biotyping by other methods; some inconsistent findings were obtained for Methyl red
and Voges Proskauer reactions.

Identification of Burkholderia multivorans were based on physical characterization such as gram staining and the biochemical characterization such as Catalase test, Oxidase test, Methyl red
test, Indole test, Nitrate reduction test, Citrate utilization test outlined in Bergey's Manual of determinative bacteriology (14).
Five drops of methyl red
were added to each tube after incubation and gently shaken.
Furthermore, the isolate exhibited positive results in oxidase, catalase, indole, methyl red
, esculin hydrolysis, nitrate reduction, ONPG test, arginine dehydrolase test, urease, gelatin liquefaction, casein hydrolysis and DNase test presented in table 2.
