Study of Yeast Production of Pectinase Enzyme and the Effect of Different Physiological Conditions on Its Production

Pectinase enzymes are considered industrially important enzymes, and their importance is due to their use in many industries, such as extracting and liquefying fruit and vegetable juices, paper and textile industry, tea and coffee brewing, extracting oils with removing gum from plant fibers and treating factory wastes containing pectic substances. Microorganisms such as bacteria and fungi, including yeasts, produce pectinase enzymes on a commercial scale. Recently, it has been noticed that there has an increase in interest in its production of yeasts due to its characteristics, ease of development, and short time required for incubation.

The Genetic Stability in the Plant

The plant breeder is interested in introducing genotypes with good performance under different environmental conditions. The response of these structures to changes in the environment and the consequent instability in their traits when grown in different environments is to determine the superior ones and to estimate the overlap between the genotypes and the environment from the important criteria, therefore, the performance of the genotype is tested in different locations and seasons to determine the stability of the varieties.

Production of Ethanol from Immobilized Saccharomyces cerevisiae

Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic chemical compound S. cerevisiae is the most employed yeast for ethanol production at the industrial level though ethanol is produced by an array of other yeasts, bacteria, and fungi. This paper reviews the current and nonmolecular trends in ethanol production using S. cerevisiae. Ethanol has been produced from a wide range of substrates such as molasses, starch-based substrate, sweet sorghum cane extract, lignocellulose, and other wastes The study was carried out on ethanol production from Immobilized Saccharomyces cerevisiae The immobilization was done with calcium chloride and sodium alginate the beads were formed. Fermentation was carried out for 7 to 8 days at 28°C then distillation was done and final ethanol produce was checked with an alcohol meter and ethanol produce was 13% from immobilized Saccharomyces cerevisiae. The process parameters optimized were substrate conc, pH, and urea conc. The values of the process parameters are 30% substrate conc, pH 4.5, and urea conc 0.5%.

Synergistic Activity of Phenolic Compounds of Some Plants Against Bacteria

Medicinal plants produce great groups of secondary metabolites which are essential for medicine purpose, one of them phenolic compounds, antimicrobial activity of phenolic compounds which derivative from plants has been examined for several years. The phenolic extracts of Sesamum indicum and Pimpinella anisum seeds have antibacterial action against Gram positive (Staphylococcus aureus) and Gram-negative bacteria (Escherichia coli), (Acinetobacter baumannii), and (Pseudomonas aeruginosa) (Proteus mirabilis). The current findings show that the synergistic impact of phenolic extracts from S. indicum and P. anisum is active against a variety of pathogenic bacteria, and that the synergistic effect for two plants is more antibacterial than phenolic extracts from one plant. The results indicated Gram- negative (P. aeruginosa) more effected by plants, than Gram-negative (S. aureus) which have the lower effects. The results of HPLC indicated Sesame (S. indicum) have total concentration of phenolic compounds was (1313.7 µg/ml) higher than total concentration of phenolic compounds of Anise (P. anisum) (220.991 µg/ml), and have varied types of phenolic compounds were Pyrogallol, Gallic acid, Rutin, Kaempferol, Cinnamaldehyde, Qurctin, Eugenol, Lignan with different concentration. From this study may be conclusion Synergistic effect for two plants have more antibacterial than phenolic extracts of one plant, and Sesame (S. indicum) have higher antimicrobial activity than Anise (P. anisum).

Detection of the Active Compounds of the Hot Aqueous Extract of Cinnamomum cassia using FTIR Technology and Testing as Anti-bacterial and Antioxidant

The results of the FTIR analysis of the hot aqueous extract of bark indicated that it contains many groups and active compounds, and the results of the bacterial tests conducted by digging and spreading method showed a high inhibitory activity of the hot aqueous extract of cinnamon against all pathogenic bacterial strains and at different concentrations. It was observed that the highest efficacy of the extract was against bacteria an inhibition diameter of 35 mm at concentration 800 mg/mL in Bacillus sp. while the bacterial strains were resistant to most of the antibiotics, in the study (Amoxicillin, Gentamycin, Ampicillin, Erythromycin, Tetracycline) except for gentamicin, which showed inhibition of bacteria Staphylococcus aureus with a diameter 19mm and Serratia sp. in diameter17mm. We conclude from the study that the cinnamon plant contains many active compounds and that the hot aqueous extract of Cinnamomum cassia (cinnamon) bark has a high inhibitory ability for different bacterial strains, which exceeded the inhibitory ability of antibiotics.

A Hybrid Differential Transforms and Finite Difference Method to Numerical Solution of Convection–Diffusion Equation

In this work, we discuss a hybrid-based method on differential transforms and a finite difference method to numerical solution of convection–diffusion equation with Dirichlet’s type boundary conditions. The developed method is tested on various problems and the numerical results are reported in tabular and figure form. This method can be easily extended to handle non-linear convection–diffusion partial differential equations.

Review Article: Vitamin C Progress Apoptosis in Breast Cancer

The cancer of breast is virulence in female and is curable in ~70–80% of patients. The vitamin type C is an essential vitamin and consider as an anti-oxidant, so this vitamin could recover the supply for oxygen, stopping the destroy of DNA and other impact necessary in cancer processing. The vitamin C indicate as an active anticancer as the concentricity were monitor in this cancer therapy. The concentricity of this vitamin has a main function in cancer-rising or cancer suppression. These studies have shown a relationship between the vitamin and increase death-rate of breast cancer, so it’s important to detect the anticancer prospective of vitamin C to detect the different among its effect in healthy and damage cells, especially these studies conducted that this difference could depend on the vitamin c concentration. These studies indicate that large doses of vitamin c could decrease the effect of some cancer therapy such as radiation and chemotherapy.

In Vivo Histological Study the Potential of Borago officinalis on Spleen and Testis Histo-Architecture on CCL4 Induced Albino Male Mice

History of medicine and plants dates backside to seclude past when herbal treatment was used and be the only answer to all kind of pain and disease. Nowadays, greater prominence is again to use phytotherapy all over the world. Herbal medicine is a traditional or folk medicine that based on the use of plants’ seeds, berries, roots, leaves, barks, flowers and plant extracts for medicinal purposes. This research study focused the line on the potentail of aqueous and methanolic extract of Borago officinalis (Borago; BO) on spleen and testis of albino male mice alone or after interaction between both plant extracts with CCL4 (toxic compound) in comparison to controls group (negative control; without any treatment and positive control; mice treated with CCL4 only). The results indicated the ability of plant extracts to modulate toxic effect resulted from CCL4 treatment.
