	Použití specifických aktinomycetových PCR primerů k charakterizaci bakteriálních společenstev exkrementů žížal Hill, P. ; Krištůfek, Václav ; Feijoo, A. M. ; Gallego, G. Tropical geophageous earthworms stimulate soil bacterial activity in soil that they ingest; it is uncertain if they affect the whole bacterial population or only subgroups. We sampled .i.Martiodrillus heterostichon, Polypheretima elongata./i. and bulk soil from a Bamboo plantation near Cali, Colombia. Pots of 1500 g of an adjacent tobacco field soil were brought to field capacity and two worms of each species placed in each pot. .i.Martiodrillus./i. gut contents and wormcasts from the soil surface and within tunnels were sampled after three months. The soil was maintained at field capacity for a further five months during which the worms continued to produce casts. Worm cast Amplified ribosomal DNA restriction analysis ARDRA (using Tag I) with actinomycete specific primers gave two strong bands at approximately 750 and 370 bp. ARDRA patterns from the three bamboo grove and four field soils had several additional bands notably at 140 and 126 bp. Detailed record
	Ovlivňuje obsah buněčných mastných kyselin a enzymů jeskynních bakterií potravní preferenci .i.Enchytraeus crypticus./i. (Oligochaeta, Enchytraeidae)? Krištůfek, Václav ; Elhottová, Dana ; Šustr, Vladimír ; Lasák, R. ; Kováč, L. ; Mock, A. ; Luptáčik, P. Cellular fatty acid screening (MIDI System) of 93 bacterial strains isolated from the Domica Cave in the Slovak Karst region ( Slovakia) showed that three bacterial strains (.i.Chryseobacterium./i. sp., .i.Enterobacter amnigenus, Rhodococcus./i. sp.) produce polyunsaturated fatty acids (PUFA) 18:3w6 and 20:4w6. These species (along with a non PUFA producer, .i.Rhizobium./i. sp.) were isolated from the gut content or body surface of .i.Mesoniscus graniger./i. (Frivaldsky, 1865) (Crustacea: Isopoda). Bacterial strains were tested for activity of nine saccharolytic enzymes. .i.Chryseobacterium./i. sp. showed amylase, maltase and cellobiase activity, other bacterial species only had amylase activity. As PUFA and enzymes may be essential for animal growth and development, colonies of the four strains were grown for further use in laboratory food selection and reproduction experiments with .i.E. crypticus./i..
