Factors influencing pigment production
A range of factors, including species composition and relative abundance, biological productivity, water chemistry, and geographic location, may affect the pigment production of marine microbial communities. These variables include light intensity and spectral composition (mediated by lake depth, water-column transparency, and other variables like the duration and extent of winter weather (Hodgson et al., 2004). Due to their impact on the economy and practicability of any pigment production process, the optimization of microorganism growth conditions, particularly physical and nutritional parameters, is essential (Gopal et al., 2013). The temperature at which microbial pigments are produced varies greatly depending on the type of microbe, as well as the carbon supply (glucose, fructose, lactose, maltose, galactose, etc.) and nitrogen source (depending on the microorganism). Minerals play an important part in the synthesis of pigments (Susmita Mishra, 2014)
