Fruit body yields and biological efficiency (BE) recorded were all highest in cultures of C. guangdongensis supplemented with sucrose and KNO(3) as carbon and nitrogen supplements, respectively. Highest fruit body yields and BE values were recorded with C : N ratio of 12 : 1. The optimal medium consisted of (g l-1) 20 center dot 0 sucrose, 4 center dot 0 soya bean powder, 5 center dot 0 beef extract and 10 center dot 0 KNO(3). Cultivation experiments using this medium confirmed its reliability; 18 center dot 35% of BE was obtained, compared with a calculated maximum BE of 18 center dot 65% based on orthogonal test data.
Conclusions:
Cordyceps
guangdongensis preferred sucrose and potassium nitrate as best carbon and nitrogen supplements. It produced satisfying yield learn more of fruit body with optimized medium.
Significance and Impact of the Study:
Optimized artificial cultivation conditions could promote the yield of C. guangdongensis and decreased the cost of production.”
“To obtain measurements of the normal fetal brain before 24 weeks
of gestation (GW), a deadline for medical decisions Gemcitabine concentration on fetal viability in a large number of countries.
We retrospectively reviewed 70 normal MR examinations of fetuses aged GW 17 to 23. The fronto-occipital diameter, the cerebral bi-parietal diameter, the transverse cerebellar diameter, the vermian height, and antero-posterior diameter were measured.
The median, maximum, and minimum values for each parameter were displayed for each individual GW.
The recorded data might contribute to a better assessment of fetal health by providing normal boundaries for the brain growth.”
“Aims:
Study of the potential of Lactococcus lactis CECT-4434 as a biosurfactants and nisin (the only bacteriocin allowed to be used in the food industry) producer for industrial applications, exploiting the possibility of recovering separately both metabolites, taking into account that BGJ398 L. lactis is an interesting micro-organism with several applications in the food industry because it is recognized as GRAS.
Methods
and Results:
The results showed the ability of this strain to produce cell-bound biosurfactants, under controlled pH, and cell-bound biosurfactants and bacteriocins, when pH was not controlled. Three extraction procedures were designed to separately recover these substances.
Conclusions:
The strain L. lactis CECT-4434 showed to be a cell-bound biosurfactants and bacterocins producer when fermentations were carried out under uncontrolled pH. Both products can be recovered separately.
Significance and Impact of the Study:
Development of a convenient tool for the extraction of cell-bound biosurfactants and bacteriocins from the fermentation broth.”
