anaerobic digestion is a feasible technology to stabilize the solid waste generated inslaughterhouses obtaining significant quantities of biogas, considered as a clean and renewable fuel. this iswhy it is important to optimize the digestion process in order to eliminate organic matter and maximize theproduction of biogas. in this work, a system was developed for treating slaughterhouse solid wa...

The production of biogas from food waste is a good approach to the minimization and increase in renewable energy. However, use as feedstock for currently poses difficulty due an ineffective hydrolysis process, which pretreatment procedure initial step conversion process. This restriction results polymers’ solubilization breakdown. has impact on volume produced during methanogenesis stage. It es...

ABSTRACT- The effects of inoculum density and temperature on the disease intensity of Phytophthoraparsiana on almond seedlings were investigated. Almond seeds (Rabie and Kaghazi cultivars) were placed in moist vermiculite at 4°C for 45 days. Germinated seeds were sown in a soil: sand mixture (2:1 v/v) and grown in greenhouse (18°C-25°C). One-month-old seedlings were transferred from the greenho...

Pasteuria penetrans will build-up faster where there is a high initial nematode density and can suppress root-knot nematode populations in the roots of tomato plants. The effect of different initial densities of nematode (Meloidogyne javanica) (150, 750, 1500, 3000) and P. penetrans infected females (F1, F3) densities (F0=control and AC=absolute control without nematode or P. penetrans inoculum...

Streptokinase is an extracellular protein secreted by various strains of streptococci and is used clinically as an intravenous thrombolytic agent for the treatment of acute myocardial infarction. It is well established that the fibrinolytic activity of streptokinase originates in its ability to activate plasminogen. The present investigation was carried out to determine the extent of streptokin...

The growth lag phase during microbial fermentation reduced productivity and equipment efficiency. Inoculum age and size were the two important variables considered in fermentation optimisation. Previous studies investigated these two variables separately, in contrast to the orthogonal or use of response surface modelling method by recent papers. In nearly all cases, the inoculum from the late e...

Aim: Response surface methodology (RSM) model was applied to optimize ethanol production from Calabash (Crescentia cujete) pulp juice using Cronobacter malonaticus. Study Design: The squeezed with muslin cloth, and vacuum filtered clear solution before use. tested for reducing sugars the Dinitrosalicylic acid (DNS) method. Twenty three (23) runs, including 3 controls, of fermentation conducted ...

A large-scale statistical experimental design was used to determine essential cultivation parameters that affect biomass accumulation and geraniol production in transgenic tobacco (Nicotiana tabacum cv. Samsun NN) cell suspension cultures. The carbohydrate source played a major role in determining the geraniol yield and factors such as filling volume, inoculum size and light were less important...
