“…Most phenotypic tests have been published previously (Bowman et al, 1997b). Flexirubin pigments were detected by suspending cells in 20 % (w\v) KOH, with a colour change from yellow or orange to brown-red indicative of a positive result (Fautz & Reichenbach, 1980). The detection of extracellular glucans by the Congo red absorption test was performed by flooding plates with 0n01 % (w\v) Congo red (McCurdy, 1969).…”

“…Growth in marine broth at different temperatures of 10°C, 25°C, 37°C and 50°C, at different pH of 4,7 and 10 were performed to characterize the growth of organisms. Flexirubin production by the isolates was tested by the method of Fautz and Reichenbach (1980). Haemolytic activity of the cultures was tested using blood agar.…”

A b s t r a c tCarotenoids are known to possess immense nutraceutical properties and microorganisms are continuously being explored as natural source for production of carotenoids. In this study, pigmented bacteria belonging to Flavobacteriaceae family were isolated using kanamycincontaining marine agar and identified using the molecular techniques and their phenotypic characteristics were studied along with their potential to produce carotenoids. Analysis of random amplification of polymorphic DNA (RAPD) banding patterns and the fragment size of the bands indicated that the 10 isolates fall under two major groups. Based on 16S rRNA gene sequence analysis the isolates were identified as Vitellibacter sp. (3 isolates), Formosa sp. (2 isolates) and Arenibacter sp. (5 isolates). Phenotypically, the isolates showed slight variation from the reported species of these three genera of Flavobacteriaceae. Only the isolates belonging to Vitellibacter and Formosa produced flexirubin, a typical yellow orange pigment produced by most of the organisms of the family Flavobacteriaceae. Vitellibacter sp. and Formosa sp. were found to produce higher amount of carotenoids compared to Arenibacter sp. and zeaxanthin was found to be the major carotenoid produced by these two species. The study indicated that Vitellibacter sp. and Formosa sp. can be exploited for production of carotenoids, particularly zeaxanthin. K e y w o r d s: Arenibacter sp., Flavobacteriaceae, Formosa sp., Vitellibacter sp., carotenoid, zeaxanthin

“…Acid production from carbohydrates was determined in mineral salt medium supplemented with various carbohydrates as described (Smibert and Krieg 1981). Flexirubin-type pigments were tested for 5 d cultures by the KOH test of Fautz and Reichenbach (1980). The degradation of native cellulose was tested by placing sterile Whatman No.…”

A new facultatively anaerobic, Gram‐negative bacterium, Cytophaga sp. LX‐7, degrading crystalline cellulose completely, was isolated from soil by dilution plating on cellodextrin agarose plates. This strain could excrete extracellularly all three types of cellulase and cellulosic substrates were the strongest inducer of endocellulase with CMC‐liquefying activity production. No reducing sugar was found in cultures of cellulose during incubation. An enzyme which degrades crystalline cellulose was detected in cultures of cellulose by measuring the formation of soluble carbohydrate but was not detected by determining the reducing sugar released. This strain also synthesized cell‐bound cellobiose oxidizing enzyme which was previously noted only in fungi. Both cellulose and soluble sugars could promote the production of cellobiose oxidizing enzyme.
