New enzymes to address industrial problems are searched among a collection of more than 25,000 classified microorganisms. These microorganisms cover a broad range of habitats, from garden soil to extreme conditions (volcanoes, polar ice, and deep-sea environments). This biodiversity multiplies the number of possible derivable enzymes nature is the basis for all its products. 

In the 1970s, the presumed dominant source of soil Pb contamination was Pb-based house paint (Ter Haar and Aronow, 1974). A subsequent study of garden soils conducted in metropolitan Baltimore,... 

The quantity and distribution of soil Pb have been studied in numerous places in North America (see Laidlaw Filippelli, 2008). All these North American cities exhibited the same distance decay characteristic of high soil Pb contamination in the inner city and decreasing contamination toward the outer parts of the city as initially identified in garden soils of Baltimore (Mielke et al. 1983). Further, similarities in this distance decay pattern of soil Pb supports the idea... 

In laboratory tests, several fungi and cultures of actinomycetes isolated from garden soil readily degraded disulfoton (Bhaskaran et al. 1973). In flooded soil under anaerobic conditions, the reduction of disulfoton sulfoxide to disulfoton was due to biological conversion (Tomizawa 1975). 

Molinate has a low toxicity to rats, oral LDso=720 mg/kg, and is rapidly metabolized by plants to CO2 (1) (5) and naturally occurring plant constituents (1). Molinate is also readily metabolized by soil microorganisms (6). After incubation of molinate with Bacillus sp. 24, Nocardia sp. 119, and Micrococcus sp. 22r which were isolated from Russian garden soils and rice field drains (7,8), it was found that molinate was completely degraded into various hydroxy and oxidized products in the medium. Molinate can be metabolized to its corresponding sulfoxide in the mouse in vivo and by the microsome-NADPH system of mouse liver (9, 10). Hubbell et al. (11) and DeBaun et al. (12) also found molinate sulfoxide along with other polar and nonpolar metabolites in rat urine.

Soil can have a dramatic effect on plant health. Get to know your garden soil (see pp.26-31) and, where necessary, improve its structure and fertility. Composted organic materials can help to reduce pest and disease levels in the soil, and to grow plants less prone to attack. 

Wild flowers grow best in poorer soil, not in cultivated and enriched garden soil. Start by digging over the area, turning over the richer topsoil and burying it beneath poorer subsoil. 

Don t be tempted to save money by digging up garden soil and putting it in your containers. Even healthy topsoil, once placed in a pot, can become hard and compacted, making it difficult for plant roots to grow.

In the laboratory, each soil sample (40 g) was transferred to a centrifuge bottle. Since the original purpose of the soil collection was to monitor specific organic compounds in the sludge-amended garden soils, a set of surrogate compounds was added to the soil prior to extraction to assess the extraction and cleanup recovery.

Organic materials may also be placed in a layer over garden soil and allowed to compost where they are to be used. This is called sheet composting. A more detailed discussion of composting is available in Extension PB 1479, Composting Yard, Garden and Food Wastes at Home. ... 

Organic gardeners use several substances besides manure to add nutrients to garden soils. Some are widely available, while others are available only via mail order or in small locahzed areas. The composition of these substance also varies widely. Some of the more commonly found organic fertilizers and the appropriate ranges of nutrient concentrations are given in Table 5.

In the eighties, the bioconversion of monoterpene alcohols by fungi had not been studied intensively [32]. However, a strain of Aspergillus niger was isolated from garden soil, able to transform geraniol, citronellol and linalool to their respective 8-hydroxy derivatives. This reaction was called fu-hydroxylation [39,40]. 

Only few literature data are available about the fungal biotransformation of linalool and its acetates. As mentioned before, the biotransformation of linalyl acetate by Aspergillus niger isolated from garden soil was studied [39,40]. Part of the unmetabolised substrate was...
