A comparison of industrial lactose obtained by roller compaction with spray dried lactose and α-lactose monohydrate using compression analysis techniques [PDF]

open access: yesJournal of Excipients and Food Chemicals
The aim of this study was to develop a lactose excipient using a production-scale roller compactor suitable for use in the pharmaceutical industry. The physical properties and compression behavior of the roller compacted lactose were investigated using ...

Analysis of the lactose metabolism in E. coli using sum-of-squares decomposition [PDF]

open access: yes, 2005
We provide a system-theoretic analysis of the mathematical model of lactose induction in E.coli which predicts the level of lactose induction into the cell for specified values of external lactose.

Agro-waste: a potential fermentation substrate for Penicillium chrysogenum [PDF]

open access: yes, 2009
Common agro-wastes found in Lagos, Nigeria (cassava shavings, corncob, sawdust, and sugarcane pulp) were compared with glucose and lactose as fermentation substrates for Penicillium chrysogenum PCL501.

Bistability of the lac operon during growth of Escherichia coli on lactose and lactose + glucose [PDF]

open access: yesarXiv, 2007
The lac operon of Escherichia coli exhibits bistability. Early studies showed that bistability occurs during growth on TMG/succinate and lactose + glucose, but not during growth on lactose. More recent studies with lacGFP-transfected cells show bistability with TMG/succinate, but not with lactose and lactose + glucose.

Lactose Intolerance in Adults: Biological Mechanism and Dietary Management

open access: yesNutrients, 2015
Lactose intolerance related to primary or secondary lactase deficiency is characterized by abdominal pain and distension, borborygmi, flatus, and diarrhea induced by lactose in dairy products.

Metallo-Dielectric Multilayer Structure for Lactose Malabsorption Diagnosis through H2 Breath Test [PDF]

open access: yesarXiv, 2007
A metallo-dielectric multilayer structure is proposed as a novel approach to the analysis of lactose malabsorption. When lactose intolerance occurs, the bacterial overgrowth in the intestine causes an increased spontaneous emission of H2 in the human breath.

Standard and Specialized Infant Formulas in Europe: Making, Marketing, and Health Outcomes [PDF]

open access: yes, 2019
Infant formulas are the only suitable substitute for human milk. The most common infant formulas are standard formulas based on cow's milk. In addition, there are formulas for infants showing signs and symptoms of intolerance and for clinical conditions ...

Cellulase hyper-production by Trichoderma reesei mutant SEU-7 on lactose

open access: yesBiotechnology for Biofuels, 2017
BackgroundThe induction of cellulase production by insoluble carbon source cellulose was a common and efficient strategy, but has some drawbacks, such as difficult fermentation operation, substantial cellulase loss, long fermentation time, and high ...

Dynamics of glucose-lactose diauxic growth in E. coli [PDF]

open access: yesarXiv, 2007
We present a mathematical model of glucose-lactose diauxic growth in Escherichia coli including both the postive and negative regulation mechanisms of the lactose operon as well as the inducer exclusion. To validate this model, we first calculated the time evolution of beta-galactosidase for only the lactose nutrient and compared the numerical results ...
