SOME ENGINEERING FACTORS AFFECTING FISH BY- PRODUCTS RECYCLING

Some factors affecting tannase production by Aspergillus niger Van Tieghem

One variable at a time procedure was used to evaluate the effect of qualitative variables on the production of tannase from Aspergillus niger Van Tieghem. These variables including: fermentation technique, agitation condition, tannins source, adding carbohydrates incorporation with tannic acid, nitrogen source type and divalent cations. Submerged fermentation under intermittent shaking gave the...

Some factors affecting fibrinogen precipitation by ristocetin: ultrastructure of precipitates.

Fibrinogen in aqueous solution is precipitated by the antibiotic ristocetin. This reaction is inhibited by albumin and facilitated by low temperature. Resolubilized fibrinogen clots in the presence of thrombin. Ristocetin-precipitated fibrinogen takes the form of fibrils or clumps, composed of irregularly spaced, structure-less particles. The addition of ristocetin to washed platelets suspended...

Adenosine triphosphate breakdown products as a freshness indicator of some fish species and fish products

The breakdown products of adenosine triphosphate (ATP), adenosine diphosphate (ADP), adenosine monophosphate (AMP), inosine monophosphate (IMP), inosine (Ino) and hypoxanthine (Hx) of some fish species and heated fish products were determined by high-performance liquid chromatography (HPLC) and rapid paper strip method. The K value, calculated from ATP degradation products, the percent of the s...

Some factors affecting sieving performance and efficiency

Some factors affecting survival in systemic blastomycosis.

T he finding of over 200 proved cases of blastomycosis in the state of Kentucky has aflorded interesting material to study the survival rates and factors affecting survival rates in this systemic fungus disease. The question of survival in blastomycosis is still subject to some controversy since in the original series reported by Martin and Smith1 of 117 cases in 1939, some 92 per cent of whom ...
