This study was conducted in order to evaluate effect of organic acids on broiler performance. Totally 180 chickens of Ross 308 hybrid were divided to three groups. Experimental group no. 1 (n=60) received acetic acid in drinking water with concentration 0.25% from day 1 to day 42. Experimental group no. 2 (n=60) received citric acid in drinking water with concentration 0.25% from day 1 to day 4...

Factors that influence salt absorption by plants have long been a subject of study. Only recently, however, (3, 4, 7, 8, 11, 16, 20, 23), have the effects of certain metabolic processes in the plant been recognized as intimately connected with salt absorption and accumulation. The present investigation has been concerned with the cation-anion balance in several species of crop plants with speci...

The sea-surface microlayer (SML) has different physical, chemical and biological properties compared to the subsurface water, with an enrichment of organic matter i.e., dissolved organic matter including UV absorbing humic substances, fatty acids and many others. Here we present experimental evidence that dissolved organic matter, such as humic acids, when exposed to sunlight, can photosensitiz...

The study was conducted to investigate the effects of betaine alone or combined with organic acids and inulin on ileal and total tract nutrient digestibilities and intestinal microbial fermentation characteristics in piglets. In total, 24 four-week-old barrows with an average initial body weight of 6.7 kg were used in two consecutive experiments with 12 piglets each. Betaine, organic acids and ...

Efforts are being made to express toxin genes from the bacterium, Bacillus thuringiensis (Bt) in chickpea for minimizing the losses due to the pod borer, Helicoverpa armigera. However, there is an apprehension that acidic exudates in chickpea leaves may influence the protoxin-toxin conversion in the insect midgut, and thus, reduce the efficacy of Bt toxins. Therefore, we studied the influence o...

BACKGROUND Recent advances in synthesizing valuable chemicals such as organic acids from low-cost renewable biomass through microbial fermentation have attracted great attention. However, the toxicity of organic acids presents a key challenge to the development of an economically viable fermentation process. Therefore, a platform organism that not only produces organic acids but also tolerates ...

The levels of organic acids representing metabolic pathway end products are important indicators of physiological status, and may be associated with metabolic changes in cancer. The aim of this study is to investigate the levels of organic acids in cancerous and normal tissues from gastric cancer patients and to confirm the role of metabolic alterations in gastric carcinogenesis. Organic acids ...

The objective of this study was to determine the effects of organic acids and monensin on the in vitro fermentation of cracked corn by mixed ruminal microorganisms. Ruminal fluid was collected from a steer fed 36.3 kg of wheat silage and 4.5 kg of concentrate supplement once daily. Mixed ruminal microorganisms were incubated in anaerobic media that contained 20% (vol/vol) ruminal fluid and .4 g...

Organic acids are formed in food as a result of metabolism of large molecular mass compounds. These organic acids play an important role in the taste and aroma of fermented food products. Doenjang is a traditional Korean fermented soybean paste product that provides a major source of protein. The quantitative data for volatile and non-volatile organic acid contents of 18 samples of Doenjang wer...

In recent years comparative studies have been made betwveen chlorotic plants and healthy plants to determine if any consistent distortion of the normal metabolic pattern occurs irrespective of the cause of chlorosis. Experiments by Iljin (6) indicated a greater amino acid and organic acid content in chlorotic leaves from grape plants grown on calcareous soil than in normal green leaves. DeKock ...
