Finally, Part III also includes two reviews (Chapters 17 and 19) of the relative risks and novel strategies available to reduce mycotoxin and enteric pathogen contamination in organic crop production systems, for mycotoxin and fungal alkaloid contamination in organic and conventional production systems (Chapter 17) and for the microbiological safety of fruit and vegetables (Chapter 19).

New transgenic production systems are emerging that possess the potential to become industrially successful (e.g., transgenic moss, lemna, fungal or yeast expression systems, transgenic animals and... 

Cellulases are found in fungi and bacteria. Of commercial interest are fungal enzymes from Aspergillus or Trichoderma and a few bacterial enzymes. They are either used as a multicomponent, which contain all enzyme types and are found in Trichoderma reesei (Hypocrea jecorina), or as a monocomponent enzyme product, which consists of only one of the three types of enzymes. The multicomponent enzyme preparations can be produced from a selected cellulose overproducing strain of the wild-type organism, whereas the monocomponent cellulases are mainly produced in recombinant production systems. 

Mycotoxins The mycotoxins are secondary products of fungal metabolism. Numerous mycotoxins have been identified as toxicants in humans and/or animal models with several organ systems, including the kidney, being targets for these fungal products. Perhaps the two mycotoxins that have received the most attention as nephrotoxicants are citrinin and ochratoxin A. These two mycotoxins have received particular interest due to their possible role in endemic Balkan nephropathy. 

The innate immune system relies on a series of cytokine cascades to achieve a rapid and massive neutrophil influx when needed. The first step of this cascade consists of the activation of sentinel cells, usually tissue macrophages or mast cells, by bacterial or fungal products. Macrophages then immediately release potent early response cytokines, such as lL-1 p andTNF-a, that act in a paracrine manner on nearby stromal cells and in an autocrine manner on the macrophages themselves, causing the release of massive amounts of proinflammatory chemokines. The local production of appropriate chemokines ultimately leads to the transendothelial migration of neutrophils from the peripheral blood. 

Absolute hypersensitivity to the drug or any other component of the product. Active or suspected ocular or periocular infection (herpes simplex keratitis, vaccinia, varicella, mycobacterial disease or fungal infection), systemic fungal infections, advanced glaucoma or concurrent administration of live vaccines in patients receiving immunosuppressive doses. 

Some corrosion inhibitors can encourage the production of fungal growths in the relatively static cold water in the header tanks of these systems. Biocides will then often need to be included in the inhibitor formulation. 

The pH has to be controlled - the acid which is produced has to be neutralised maintaining a pH in excess of 6.0. Below pH 3.0 the glucose oxidase is inactivated and in fungal systems low pH encourages citric add production.
