Reassessment of the estimation of dissolved oxygen concentration profile and K(L)a in solid-state fermentation
(ELSEVIER SCI LTD, 2000)
Oxygen mass transfer in aerobic microbial growth systems is often a limiting factor for optimal growth and productivity. Oxygen mass transfer has been widely studied in submerged fermentations but has attracted as yet ...
Intraspecific variation of heat tolerance in a model ectotherm: The role of oxygen, cell size and body size
(2023)
Virtually all aspects of the biology of ectotherms are size-and temperature-dependent. Aerobic metabolism is often proposed to explain such relationships, with oxygen limitation setting limits to heat tolerance and ...
Randomized trial of early bubble continuous positive airway pressure for very low birth weight infants
(Elsevier, 2012)
Objective: To determine whether very low birth weight infants (VLBWIs), initially supported with continuous positive airway pressure (CPAP) and then selectively treated with the INSURE (intubation, surfactant, and extubation ...
Engineering an anaerobic metabolic regime in Pseudomonas putida KT2440 for the anoxic biodegradation of 1,3-dichloroprop-1-ene
(Academic Press Inc Elsevier Science, 2013-01)
Pseudomonas putida KT2440, a microbial cell factory of reference for industrial whole-cell biocatalysis, is unable to support biochemical reactions that occur under anoxic conditions, limiting its utility for a large number ...
Feasibility of noninvasive positive pressure ventilation in the treatment of oxygen-dependent COVID-19 patients in Peru
(American Society of Tropical Medicine and Hygiene, 2021)
Intensive care is expensive, and availability is limited. Low- and middle-income countries in particular have struggled to cope with the large influx of critically ill patients during the COVID-19 pandemic. Noninvasive ...
Fossil bubble structure related to microbial activity coeval with the middle Ediacaran Oceanic Oxygenation Event in the Tandilia System
(Asociación Argentina de Sedimentología, 2021-10)
The well-preserved limestone succession, Loma Negra Formation (~40 m), in the Tandilia System was deposited in a shallow carbonate ramp under low energy conditions. The evolution in the depositional settings of the unit ...
Redox-sensitive trace element distribution in the Loma Negra Formation in Argentina: The record of an Ediacaran oxygenation event
(Elsevier Science, 2019-09)
The limestones of the Loma Negra Formation provide an excellent opportunity to examine the behaviour of rare earth elements plus yttrium (REY) due to the near-zero diagenetic alteration of the carbonate system. The terrigenous ...
Implementação de sistema nebuloso (“fuzzy”) para controle de oxigênio dissolvido no cultivo de Escherichia coli para expressão de proteínas recombinantes
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2022-04-27)
Due to low oxygen solubility in water and mechanical limitations of a bioreactor, ensuring an adequate dissolved oxygen supply during a recombinant Escherichia coli cultivation is a major challenge in process control. In ...
