Orange peel extract solution contains mucilage flavor and three types of glycosides. Limonene is one of the terpenoides in some vegetables, fruits and food; that plays as an antioxidant in juice. As it has anti-microorganism effects on some bacteria, we carried out the antifungal effects of limonene versus orange extract. In the present study the effects of orange extract and two types of limon...

background: in algeria the date wastes production is estimated at least 85.000 tones. date wastes is an economic source of carbohydrates for conversion to industrial enzymes because it is readily available and relatively low priced.objective: the aim of the present study was to investigate the potential of using date wastes as a substrate for the production of a-amylase and invertase. materials...

Microorganisms have provided a bounty of bioactive secondary metabolites with very exciting biological activities such as antibacterial, antifungal antiviral, and anticancer, etc. The present study aims at the optimization of culture conditions for improved antimicrobial production of Paenibacillus elgii obtained from Wayanad forest of Western Ghats region of Kerala, India. A bacterial strain i...

OBJECTIVE The effects of lactic acid bacteria (LAB) and cellulase enzyme on fermentation quality, microorganism population, chemical composition and in vitro gas production of sorghum silages were studied. METHODS Commercial inoculant Lactobacillus plantarum Chikuso 1 (CH), local selected strain Lactobacillus casei (L. casei) TH 14 and Acremonium cellulase (AC) were used as additives in sorgh...

BACKGROUND Sustainable and economically viable manufacturing of bioethanol from lignocellulose raw material is dependent on the availability of a robust ethanol producing microorganism, able to ferment all sugars present in the feedstock, including the pentose sugars L-arabinose and D-xylose. Saccharomyces cerevisiae is a robust ethanol producer, but needs to be engineered to achieve pentose su...

Production of high value products from glycerol via anaerobic fermentation is of utmost importance for the biodiesel industry. The microorganism Escherichia coli (E. coli) K12 was used for fermentation of glycerol. The effects of glycerol concentration and headspace conditions on the cell growth, ethanol and hydrogen production were investigated. A full factorial experimental design with 3 repl...

The inhibitors present in dilute acid-treated lignocellulosic hydrolysates would show great effect on the growth and product formation of microorganisms. To understand their inhibitory law and mechanism on oleaginous microorganism could help improving the efficiency of lignocellulose hydrolysis, detoxification, and lipid fermentation. The effects of four representative alcohol compounds present...

Much interest has been generated over the past few years aimed at evaluating alternative means to manipulate the gastrointestinal microflora in production livestock. Motivation for examining these alternatives comes from increasing public scrutiny about the use of antibiotics in the animal feed industry. However, compared to the amount of information available detailing the effects of antimicro...

background and objective: garlic, in different types, is a very common food ingredient all over the world. traditionally, garlic is fermented in grape vinegar to produce garlic pickles; in this study, to produce a novel fermented food, garlic was fermented in kombucha beverage; then, antibacterial and chemical properties and color changes of garlics fermented in kombucha and vinegar were compar...
