“…6). Similar results were reported by Usman et al, (2018) where the orange pigment produced by Salinococcus roseus under shaking incubation was approximately three times the pigment produced under non-shaking incubation. The nutrients also play a very significant effect on the metabolic activities of all the living organisms, hence the effect of carbon and nitrogen on pigment production was assessed.…”

“…According to a study conducted by Tangarini and Mishra [35] on the production of melanin by a soil isolate, optimal conditions were at pH 7.0-8.5, 25-30 • C and agitation speeds ranging from 140-180 rpm. Similar findings were reported by Usman et al [36] on the production of orange pigment by a soil isolate. From Figure 3, it is apparent that pH affected pigment production.…”

The food and pharmaceutical industries are searching for natural colour alternatives as required by consumers. Over the last decades, fungi have emerged as producers of natural pigments. In this paper, five filamentous fungi; Penicillium multicolour, P. canescens, P. herquie, Talaromyces verruculosus and Fusarium solani isolated from soil and producing orange, green, yellow, red and brown pigments, respectively, when cultured on a mixture of green waste and whey were tested. The culture media with varying pH (4.0, 7.0 and 9.0) were incubated at 25 °C for 14 days under submerged and solid-state fermentation conditions. Optimal conditions for pigment production were recorded at pH 7.0 and 9.0 while lower biomass and pigment intensities were observed at pH 4.0. The mycelial biomass and pigment intensities were significantly higher for solid-state fermentation (0.06–2.50 g/L and 3.78–4.00 AU) compared to submerged fermentation (0.220–0.470 g/L and 0.295–3.466 AU). The pigment intensities were corroborated by lower L* values with increasing pH. The λmax values for the pigments were all in the UV region. Finally, this study demonstrated the feasibility of pigment production using green waste:whey cocktails (3:2). For higher biomass and intense pigment production, solid-state fermentation may be a possible strategy for scaling up in manufacturing industries.

“…In this study, pigment was produced between 20 0 C and 45 0 C with maximum production at 20 0 C (Fig 3) with OD value of 1.1 at 515nm. The results of this is similar with the results reported by (Usman et al, 2018), who indicated that, the UV-Visible results of the extracted pigments was generated at a wavelength region between 200-800nm. The orange pigment produced by Salinococcus roseus showed highest peak of 450nm which gradually declined toward visible region.…”

At present, due to the health side effects of chemically synthesized coloring agents, naturally produced coloring agents were favored. From all naturally produced coloring sources, microbial pigments have been given precedence, due to easy manipulation of the microorganisms and optimization of the production processes. The main aim of this article is to report the characteristics and factors affecting growth and pigment production by bacterium isolate Mif41. The soil samples were collected and serially diluted from 10 -1 to 10 -6 and each dilution was plate on the sterilized Glucose, mannitol, Tryptose Yeast extract Agar (GMTYEA) medium and incubated at 28°C under aerobic condition. After 48h of incubation the yellow pigmented bacterium isolate was picked and purified by repeated streaking on GMTYEA and the pure culture was maintained on slant at 4°C. The pure culture of the bacterium isolate was characterized morphologically and biochemically. Both extracellular and intracellular pigments obtained from the bacterium isolate were analyzed by using UV-visible spectrophotometer. Effect of carbon sources, nitrogen sources, medium PH, incubation temperature and effect of salt concentrations on growth and pigment production were evaluated. The morphological and biochemical characterization of the bacterium isolate tentatively suggested as Pseudomonas sp. From the different carbon sources tested fructose favored maximum extracellular and intra cellular pigmentation while sorbitol was found minimal in this respect. All the organic sources of nitrogen stimulated growth and pigmentation while all the inorganic sources of nitrogen were inhibitory for growth and pigmentation. Incubation temperatures of 20-28°C were favored growth and pigmentation while incubation temperature above 30 were highly limiting for growth and pigmentation. Medium PH 8 found to be favorable for growth and pigmentation while acidic and basic pH were limiting for growth and pigmentation. Lower salt concentration was found to favor the growth and pigmentation, while increased concentration were found to be limiting. The results of this study clearly indicated that the bacterium isolate Mif41 is able to produce different colored pigments under different nutritional and environmental conditions suggesting that this bacterium isolate will be considered as a candidate for the industrial production of pigments which will be applied in various industries.
