Isolation, Characterization, and Optimization Studies of Bacterial Pigments

Journal of Pure and Applied Microbiology, 2022
Recent concern for human safety and environmental protection has rekindled interest in natural pigment sources. In comparison to synthetic pigments, microbial pigments show better biodegradability and environmental compatibility and are used in a variety

Microbial Pigments: Major Groups and Industrial Applications

Microorganisms, 2023
Microbial pigments have many structures and functions with excellent characteristics, such as being biodegradable, non-toxic, and ecologically friendly, constituting an important source of pigments. Industrial production presents a bottleneck in production cost that restricts large-scale commercialization.

Physiology of purple sulfur bacteria forming macroscopic aggregates in Great Sippewissett Salt Marsh, Massachusetts [PDF]

, 1993
Purple bacterial aggregates found in tidal pools of Great Sippewissett Salt Marsh (Falmouth, Cape Cod, MA) were investigated in order to elucidate the ecological significance of cell aggregation. Purple sulfur bacteria were the dominant microorganisms in

Microbiome and metagenomic analysis of Lake Hillier Australia reveals pigment-rich polyextremophiles and wide-ranging metabolic adaptations

Environmental Microbiome, 2022
Lake Hillier is a hypersaline lake known for its distinctive bright pink color. The cause of this phenomenon in other hypersaline sites has been attributed to halophiles, Dunaliella, and Salinibacter, however, a systematic analysis of the microbial ...
