Some researchers told that Pseudomonas sp. can do it to some extent. Do you have more idea or references in support of your answer. Please add your valuable thoughts.
Sure, some bacteria really can accumulate storage carbohydrates that are not used by other microbes immediately. But, comparing to green plants that produce cellulose and lignin, the amount of bacterial storage carbohydrates is very small.
Carbon capture & storage (sequestration) can be realized when genetically modified bacteria is developed so that it will trap carbon dioxide fast & keep it underground for many years to come. Bacteria has been efficient in getting rid of carbon monoxide at a constant rate & there is much hope (coming from research labs) that the other carbon oxide will become under control.
Carbon sequestration is the addition of carbon containing substances to a reservoir, e.g., the ocean, which has the capacity to store, accumulate or release carbon. Economists are interested in the timescale of carbon sequestration because companies or countries can earn carbon credits by artificially capturing and securing the storage of carbon that would otherwise be emitted to or remain in the atmosphere. Physical processes such as stratification, mixing and ocean currents influence carbon sequestration in the ocean. Increasing stratification restricts nutrient supply from deep water to the euphotic zone, and therefore primary production which will in turn impact the export of particulate organic carbon (POC). To enhance carbon sequestration in the coastal zone by controlling the discharge of nutrients from land through the integrative management of the land–ocean system, for example by using methods of fertilization which avoid loss of nutrients to rivers and reducing sewage discharge to coastal waters.
