Potentials and limitations of cold-adapted hydrogen producing bacteria: A mini review

Low-temperature bacteria have potential to produce biohydrogen and are often considered a renewable energy generator for the future. However, presented poor hydrogen yield due slow metabolic rate prolonged lag phase caused by their restricted growth temperature limit. The ineffective search new biocatalysts from cold environments application of modification techniques almost jeopardize economic viability these strains in production research. This article examined genetic enzymatic adaptation potentials that led continuous expression novel biotechnological importance under following headings; cold-adapted bacteria, biohydrogen-producing strategies adapting stress low temperatures, performance production, challenges future prospect. Finding studying unique properties can improve efficiency as this area has not yet been extensively studied.
