chrysoperla carnea is a voracious predator. it is currently mass-reared and released for biological control programs. this study was aimed at finding out the effect of different diets on biological characteristics of adult predator, and to introduce a better and cheaper artificial diet for its mass-rearing. in order to obtain a pure and physiologically homogenous population, the predator was re...

the present study was undertaken to investigate the effectiveness of the ethanolic extract of echinophora platyloba dc. on candida albicans. using the agar dilution method, the growth condition of standard candida albicans atcc 10231, cultured on the media containing plant extracts at different concentrations (1,2,4,8,16,32,64,128 and 256 mg/ml) was studied. the results were recorded twenty one...

Sequential statistical methods were used to maximise carotenoid production by a strain of Rhodotorula mucilaginosa, isolated from the Brazilian ecosystem. Initially, a factorial 2(5-1) experimental design was used, and the variables were pH and the levels of glucose, yeast extract, MgSO4.7H2O and KH2PO4. The nitrogen source (yeast extract) was the most important variable in enhancing carotenoid...

General linear (GL) methods are numerical algorithms used to solve ODEs. The standard order conditions analysis involves the GL matrix itself and a starting procedure; however, a finishing method (F) is required to extract the actual ODE solution. The standard order analysis and stability are sufficient for the convergence of any GL method. Nonetheless, using a simple GL scheme, we show that th...

In this work, the effects of medium composition and fermentation parameters on the simultaneous production of mycelial biomass and exopolymer by medicinal mushroom Hericium erinaceus CZ-2 were investigated in shake flask cultures using one-factor-at-a-time method and orthogonal array design. Results showed that the most suitable carbon, nitrogen, mineral sources, and cofactors for the mycelial ...

BACKGROUND As the most abundant renewable resources, lignocellulosic materials are ideal candidates as alternative feedstock for bioethanol production. Cassava residues (CR) are byproducts of the cassava starch industry which can be mixed with lignocellulosic materials for ethanol production. The presence of lignin in lignocellulosic substrates can inhibit saccharification by reducing the cellu...

In this work, we proposed a short-term adaptation strategy to improve xylitol production on sugarcane bagasse hemicellulosic hydrolysate through the maximization of Candida guilliermondii FTI 20037 tolerance inhibitors. Hemicellulosic obtained by diluted acid hydrolysis (1.0% (wv−1) H2SO4, 1:10 solid/liquid ratio, 121 °C, 10 min) was concentrated up fivefold obtain hydrolysates with different c...

Nowadays, consumers become interested to use the substitution of natural preservatives instead of chemical preservatives. It has been proven that pomegranate peel contains large amounts of antimicrobial and antioxidant compounds. In this study, the antimicrobial effect of ethanolic extract of pomegranate peel was evaluated on total microbial count, mold and yeast and Lactobacillus plantarum...

abstract in order to find out a better and cheaper artificial diet for mass rearing of common green lacewing, chrysoperla carnea, an experiment was conducted using completely randomized design (crd) with 4 replications and 5 observations. in this study were used three diets [a mixture of honey, yeast and distilled water (1:1:1), a mixture of honey, yeast plus extract of angomois grain moth eggs...
