| klugiella xanthotipulae gen. nov., sp. nov., a novel member of the family microbacteriaceae. | an actinobacterium, designated strain 44c3(t), was isolated in michigan, usa, from the hindgut of the larvae of tipula abdominalis, an aquatic crane fly, and was subjected to a polyphasic taxonomic investigation. phylogenetic analysis based on 16s rrna gene sequences revealed that the strain represented a separate clade within the family microbacteriaceae. it showed highest 16s rrna gene sequence similarity with cryobacterium psychrotolerans 0549(t) (96.5 %). strain 44c3(t) had a novel b-type pe ... | 2008 | 19060057 |

| isolation of polymer-degrading bacteria and characterization of the hindgut bacterial community from the detritus-feeding larvae of tipula abdominalis (diptera: tipulidae). | the tipula abdominalis larval hindgut microbial community presumably facilitates digestion of the lignocellulosic diet. the microbial community was investigated through characterization of bacterial isolates and analysis of 16s rrna gene clone libraries. this initial study revealed novel bacteria and provides a framework for future studies of this symbiosis. | 2007 | 17630316 |
| bacillus sphaericus mosquito pathogens in the aquatic environment. | the fate of bacillus sphaericus spores in the aquatic environment was investigated by suspending spores in dialysis bags in fresh and seawater. spore viability was lost more rapidly in seawater. neither b. sphaericus nor b. thuringiensis israelensis (b.t.i.) spores mixed with pond sediment appeared to attach to the sediment. however, rapid decrease in b.t.i. toxicity suggested attachment of parasporal bodies to sediment. b. sphaericus toxin settled more slowly and less completely. b. sphaericus ... | 1995 | 8524074 |

| the digestion of protein and carbohydrate by the stream detritivore, tipula abdominalis (diptera, tipulidae). | the digestive system of larvae of tipula abdominalis (diptera, tipulidae), a stream detritivore, is poorly adapted for the digestion of the major polysaccharides in its diet, but well adapted for the digestion of protein. these crane fly larvae are unable to digest the major cell wall polysaccharides of higher plants, i.e., cellulose, hemicellulose and pectin. the only polysaccharides toward which the midguts of t. abdominalis exhibited any activity were α-amylose and laminarin, indicating that ... | 1980 | 28310045 |
| bacteria associated with the gut tract of larval stages of the aquatic cranefly tipula abdominalis (diptera; tipulidae). | scanning electron microscopy, light microscopy, and direct isolations were used to examine the distribution and diversity of bacteria in the gut tracts of larval stages of tipula abdominalis. the animal had an enlarged hindgut which housed a diverse bacterial community in the lumen and directly attached to the gut wall. distinct localization was noted, with the most dense and most diverse community anterior to the rectum. a distinct architecture of bacteria occurred in this region, characterized ... | 1980 | 16345618 |
| growth and stoichiometry of a common aquatic detritivore respond to changes in resource stoichiometry. | consumer growth determines the quantity of nutrients transferred through food webs. the extent to which leaf composition and consumer physiology interact to constrain consumer production is not well understood. for example, detritivore growth, and thus material transfer, could change with detrital elemental composition. detrital type and associated microbial biofilms can mediate the amount and rate of detritus consumed and used towards growth. detritivore body stoichiometry or the threshold elem ... | 2015 | 25428786 |
