Black soldier fly (Hermetia illucens) larvae are a promising source of protein and lipid for animal feeds. The nutritional composition of the BSF larvae depend partly on the composition of the feeding medium. The BSF lipid profile in part mimics the feeding media lipid profile, and micronutrients, like minerals and vitamins, can readily accumulate in black soldier fly larvae. However, investiga...

A number of nutrient media have been described by Goodman (1954), Katagiri (1954), Niedercorn (1952), Petty et al. (1953), Van Dyke and De Somer (1952), and others that allow Streptomyces aureofaciens Duggar to grow in aerated, liquid culture and to accumulate substantial quantities of 7-chlorotetracycline.' The concentrations of 7-chlorotetracycline accumulated on these different media vary fr...

BACKGROUND The optimization of bioprocess conditions towards improved growth profile and productivity yield is considered of great importance in biopharmaceutical manufacturing. Peptones as efficient sources of nutrients have been studied for their effect on media development; however, their role on metabolic pathway is not well understood. METHODS In the present study, the effect of differen...

Many best-management practices (BMPs) currently used in urban regions have been developed to minimize flood risk, sustain downstream ecosystems, and secure the quality of groundwater sources either directly or indirectly. One such BMP is the reuse of stormwater by removing nutrients from the nutrient-laden “first flush” water collected in wet or dry ponds; this practice has led to the developme...

The application of cultural methods to the diagnosis of gonorrhoea in small clinics has been hindered in the past by the lack of laboratory facilities. The gonococcus is fastidious in its nutritive requirements and the culture media used to grow it have been elaborated by empirical methods because we have no exact knowledge of the substances necessary for its growth. In clinics not closely asso...

background and aims. current chemical methods may not efficiently disinfect dental stone casts. the aim of this study was to investigate if microwave irradiation is effective for disinfection of stone casts. materials and methods. in this laboratory study, three groups (n = 162) of prepared spherical stone beads as carriers with a diameter of 10 mm were inoculated by separately soaking in three...

Bacillus licheniformis is a spore-producing bacteria. The present study aims to identify maximum sporulation in through induced heat shock conditions using different solidified media and broth media. Suspensions of spores were spread-plated on nutrient agar plates before after treatments 60°C, 80°C 100°C for 30 minutes. number was determined by the dilution plate count method. result indicates ...

A system was evaluated for growing plants at reproducible levels of water stress. Beans (Phaseolus vulgaris L.) were grown in vermiculite, transferred to a semipermeable membrane system that encased the root-vermiculite mass, and then placed into nutrient solutions to which various amounts of polyethylene glycol (PEG) 20M were added to control solution water potential. The membrane (Spectrapor ...

Multiphase porous media mechanics is used for modeling tumor growth, using governing equations obtained via the thermodynamically constrained averaging theory (TCAT). This approach incorporates the interaction of more phases than legacy tumor growth models. The tumor is treated as a multiphase system composed of an extracellular matrix, tumor cells which may become necrotic depending on nutrien...
