The yeast Lachancea thermotolerans can produce lactic acid during alcoholic fermentation (AF) and thereby acidify wines with insufficient acidity. However, little is known about the impact of L. on Oenococcus oeni, primary bacterium used in malolactic (MLF). This study explored sequential cultures Saccharomyces cerevisiae MLF performance white red wines. Four strains were tested Sauvignon blanc...

The influence of blue-stain fungi [Ophiostoma minus (Hedgcock) H. and P. Sydow and Leptographium serpens (Goid.) Siemaszko] on absorbance at the visible and near infrared wavelengths was investigated. Forty trees were sampled at breast height from longleaf pine (Pinus palustris Mill.). One half of each increment core was inoculated with one of two fungi treatments while the other half served as...

The effects of Pratylenchus vulnus on rootstocks of eight commonly used Prunus spp. and one Pyrus communis were evaluated under greenhouse conditions during a 15-month period. In a first experiment, two almonds (Moncayo and Garrigues), one peach (GF-305), and two peach-almond hybrids (GF-677 and Adafuel) inoculated with 2,000 nematodes per plant proved to be good hosts of P. vulnus. Highest (P ...

Using the isotope dilution P technique, a study was conducted to evaluate the P uptake and growth improvement of aerobic rice genotype (M9) inoculated with phosphate-solubilizing bacteria (PSB16, Bacillus sp.) and applied with Christmas Island Phosphate Rock (CIPR), and oxalic acid (OA). An absence of PSB and OA was considered as control treatment. The inoculation of PSB16 strain and OA applica...

A series of experiments were conducted to determine the effectiveness of rapid desiccation with dry heat at one or two points in the slaughter process to reduce bacterial contamination on beef carcass surfaces. In the first set of experiments, several combinations of desiccation and water washes were examined. Beef surfaces were inoculated with bovine feces and water washed (IW; 125 psi, 15 s, ...

The potential of line-scan Raman hyperspectral imaging system equipped with a 785 nm line laser was examined for discrimination uninfected control, AF36-inoculated and AF13-inoculated corn kernels in this study. AF13 AF36 strains were used as representatives the aflatoxigenic non-aflatoxigenic A. flavus fungi. A total 300 3 treatments, namely, 100 inoculated fungus, sterile distilled water cont...

Leaf area, chlorophyll content, net CO(2) photoassimilation, and the partitioning of fixed carbon between leaf sucrose and starch and soluble protein were examined in Glycine max (L) Merr. cv Williams grown under three different nitrogen regimes. One group (Nod+/+) was inoculated with Bradyrhizobium and watered daily with a nutrient solution containing 6 millimolar NH(4)NO(3). A second set (Nod...

The effects of two entomopathogenic fungal endophytes, Beauveria bassiana and Purpureocillium lilacinum (formerly Paecilomyces lilacinus), were assessed on the reproduction of cotton aphid, Aphis gossypii Glover (Homoptera:Aphididae), through in planta feeding trials. In replicate greenhouse and field trials, cotton plants (Gossypium hirsutum) were inoculated as seed treatments with two concent...

Microbes living symbiotically in plant tissues mutually cooperate with each other by providing nutrients for proliferation of the partner organism and have a beneficial effect on plant growth. However, few studies thus far have examined the interactive effect of endophytic bacteria and arbuscular mycorrhizal fungi (AMF) in hostile conditions and their potential to improve plant stress tolerance...
