Abstract
Biotransformation of used means of personal hygiene of cosmonauts and vegetable waste as applied to life support systems for space crews
Highlights
Long terms of the planned space expeditions require the creation of the most closed LSS of crews in spacecraft with cyclic regeneration of substances in an artificial ecosystem [8]
Among the wastes that are formed in the conditions of manned space flight, a significant proportion is spent on personal hygiene
Biodegradation of personal care products using Clostridium thermocellum culture: In the present work, the effectiveness of the application of different bacterial strains for the destruction of gauze wipes was determined with a high content of the original ungrounded substrate
Summary
Long terms of the planned space expeditions require the creation of the most closed LSS of crews in spacecraft with cyclic regeneration of substances in an artificial ecosystem [8]. One of the main conditions for increasing the closure factor of LSS is the processing of waste in order to return the maximum proportion of the elements contained in them to the circulation of substances on board the MSC. Among the wastes that are formed in the conditions of manned space flight, a significant proportion is spent on personal hygiene (gauze napkins). A necessary element of the closed LSS of manned spacecraft are considered greenhouses for the reproduction of the vegetative part of the diet of cosmonauts. Used personal hygiene products and greenhouse waste accumulate will occupy significant volumes, which will lead to an increase in the equivalent weight of the system [3, 12]. In the perspective of interplanetary flights, based on the requirements of planetary quarantine, it is not possible to carry out the contaminated with microorganisms debris beyond the spacecraft
