Characterizing growth conditions in chlorine-activated diamond chemical vapor deposition
… suggests a low substrate temperature diamond growth mechanism by atomic carbon insertion reactions. Such a mechanism becomes pronounced at high atomic hydrogen concentrations and can lower the apparent growth activation energy in the low substrate temperature regime. Experiments using tubular …

Establishment and trait variation of a range expanding Brassicaceae species under various growth conditions
… spectrum of abiotic and biotic environmental conditions has been partially attributed to significant variation in several life-history traits. Some of these traits may be useful pre-adaptations, while others diverge among populations due to distinct post-introduction evolution. For example, …

Optimization of Growth Conditions of Selected Exo-Polysaccharides Producing Lactic Acid Bacteria in Whey Mineral Concentrate
… study was conducted with a view to optimize the growth of two EPS-producing bacterial cultures (Lactobacillus helveticus ATCC 15807 and Lactococcus lactis subsp. cremoris) in whey mineral concentrate (WMC). The parameters studied were TS%, incubation temperature, overnight cooling, incubation …

Interrogation of Yeast Responses to Anaerobic Growth Conditions at the Intact Protein Level Using Improved Top-Down Proteomics
Taking advantage of further development of the front-end platform and metabolic labeling quantitative strategy, top-down proteomics was employed to investigate the response of Saccharomyces cerevisiae towards anaerobiosis. Approximately 150 protein pairs were measured with 4 differential …

Evaluation of the effect of growth conditions on lipid production by Papiliotrema laurentii UFV-1 in culture media containing xylose
… vegetable oil features are affected by climatic conditions. These drawbacks can be circumvented by using alternative oil sources such as microbial oil. Oleaginous yeasts accumulate at least 20% of their dry weight as lipids, mainly in the form of triacylglycerols, nevertheless, superior values …

The effects of growth conditions on the elemental and biochemical composition of the diatom Thalassiosira weissflogii and the haptophyte Emiliania huxleyi
A change in environmental conditions often leads to changes of physiology and biochemical composition of microalgae. Temperature and light intensity are important environmental factors regulating the growth of microalgae. In this study, the elemental and biochemical composition were measured in 2 …

Investigating the nutritional and social determinants of favorable fetal growth conditions (FFGC) in pregnant women living in the Free State Province, South Africa
… a latent construct known as Favorable Fetal Growth Conditions (FFCG), that considers birth weight, birth length, and gestational age. This study was driven by the high rate of low birth weight (15%) in SA. Also, there is a gap in the literature related to the nutritional and social …

Effect of Different Growth Conditions on Cell Growth Using Biphenyl as a Sole Carbon Source by the Bacteria Isolated from Soil Samples Collected from San Jacinto River, Texas
… Coli demonstrated higher cell density growth, and was further monitored by GC-MS for canonical degradation intermediates. Based on the preliminary data, FR CSM SOY could be a putative biphenyl degrader. It was further hypothesized that if FR CSM SOY can produce some downstream …

Differential Expression Analysis of Type II Toxin-Antitoxin Genes of Pseudomonas aeruginosa PAO1 under Different Environmental Conditions
… role for bacterial survival during stressful growth environments. Pseudomonas aeruginosa PAO1 is one of the most versatile microorganisms in the environment. Despite its ubiquitous presence, no studies have shown the differential expression pattern of its toxin-antitoxins, and persistence …

The Effects of Starvation on The Ruminal Bacteria Megasphaera Elsdenii and Selenomonas Ruminantium
… to total organic nutrient starvation after growth in batch and/or continuous culture. Both organisms exhibited a very limited survival capacity in comparison to other bacteria reported in the literature. This capacity appears to have been at least partially influenced by pre-starvation …

Characterizing the Growth of Cyanobacteria Using Coiled and Bubble Column Photobioreactors and Its Separation by Flocculation Filtration
… since the photobioreactors provide ambient growth environment and higher biomass productivity for Anabaena 7120, coiled photobioreactor was developed. The basic growth conditions required were light intensity for photosynthesis, CO<sub><sup>2</sup></sub> as carbon source and air bubbling for …

Low-Pressure Metalorganic Chemical Vapor Deposition of High-Gain InGaP/GaAs Heterojunction Bipolar Transistors
The impact of the emitter and cap growth conditions on the gain of heterojunction bipolar transistors (HBTs) was studied by annealing to simulate the prolonged growth of HBTs with a heavily carbon-doped base. The results indicate that postgrowth annealing at a temperature close to the growth …

Integrated microbioreactors for rapid screening and analysis of bioprocesses
… the microbioreactor for investigating different growth conditions is confirmed by comparing bacterial growth, as evaluated by the measured parameters, under conditions of different medium and oxygen concentration. It is shown that statistical differences can be observed, and that these …

The effect of oxidation-reduction potential on the outgrowth, toxin production, and chemical inhibition of Clostridium botulinum type A spores
… of oxidation-reduction potential (Eh) on the outgrowth, toxin production, and chemical inhibition of Clostridium botulinum type A spores was investigated. Growth, toxin formation, and Eh7 changes were monitored in an airtight four necked flask containing electrodes for continuous measurement of …

Properties and Applications of Amorphous Gallium Arsenide Annealed to a Polycrystalline Form
… (MBE) in an amorphous form by lowering the growth temperature well below normal growth conditions. These growth conditions result in material that is very arsenic rich. When this material is annealed at moderate temperatures (400 to 500°C) it becomes polycrystalline and in some cases …
