The sweetpotato whitefly, Bemisia tabaci (Gennadius), B biotype, presents a unique problem for vegetable growers by serving as a vector of plant viruses and by inducing physiological disorders of leaves and fruit. An action threshold of a single whitefly is necessary because of the threat of disease in many areas and growers rely heavily on a single class of insecticides (neonicotinoids) for wh...

Efficient lactic acid production from cane sugar molasses by Lactobacillus delbrueckii mutant Uc-3 in batch fermentation process is demonstrated. Lactic acid fermentation using molasses was not significantly affected by yeast extract concentrations. The final lactic acid concentration increased with increases of molasses sugar concentrations up to 190 g/liter. The maximum lactic acid concentrat...

Sugarcane and agave bagasse samples were hydrolyzed with either mineral acids (HCl), commercial glucanases or a combined treatment consisting of alkaline delignification followed by enzymatic hydrolysis. Acid hydrolysis of sugar cane bagasse yielded a higher level of reducing sugars (37.21% for depithed bagasse and 35.37% for pith bagasse), when compared to metzal or metzontete (agave pinecone ...

An efficient and cost effective protocol for in vitro propagation of Pineapple (Ananas comosus var. Queen) has been developed. In the proliferation stage, agar based Murashige and Skoog (MS) media was supplemented with 3.0 mg/l benzyleaminopurine (BAP), 0.5 mg/l indole acetic acid (IAA) and 50 mg/l adenine sulphate as RBC design experiment. Two approaches were taken to reduce the chemical cost ...

The discrepancies across test sites and years, along with the interaction between cultivar and environment, make it difficult to accurately evaluate the differences of the sugarcane cultivars. Using a genotype main effect plus genotype-environment interaction (GGE) Biplot software, the yield performance data of seven sugarcane cultivars in the 8th Chinese National Sugarcane Regional Tests were ...

an experiment was conducted to evaluate the effect of lime application on the mass and sugar losses reduction from 2004 to 2005 in karaj. four lime concentrations of 0, 3, 4 and 5 percent (factor a) and storage durations of 30 and 60 days (factor b) were arranged as factorial experiment in rcbd with four replications. the commercial variety of shirin was drilled in early may and storage roots w...

Several carbon substrates were tried, including glucose commercial, pro analysis glucose, commercial sugar, and yeast extract - peptone d (YPD) medium to improve the efficiency of single chamber microbial fuel cell (MFC). The power production various electron donors was investigated using baker Saccharomyces cerevisiae. Voltage density generation used establish pattern substrate use. In additio...
