    Respiration of the bathypelagic fish Cyclothone acclinidens (1981)
    Springer
    Marine biology 61 (1981), S. 261-266 
    Details
    ISSN: 1432-1793
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract The respiration of 3 adult females of Cyclothone acclinidens was measured in situ. These numerically dominant fish of the meso- and bathypelagic zones were individually captured off southern California at a depth of 1300 m using a multiple-chambered slurp-gun respirometer operated from the submersible “Alvin”. Continuous oxygen consumption measurements of each fish were made at the capture depth for about 28 h, spanning an interval from late morning to the following mid-afternoon. Nocturnal rates of respiration of these fish were 3 to 5 times higher than diurnal rates, suggesting a daily thythm in this non-migratory midwater species. Environmental factors such as tides, light, and food could serve to synchronize the observed respiration fluctuation.

    Oxygen consumption of pelagic juveniles and demersal adults of the deep-sea fish Sebastolobus altivelis, measured at depth (1983)
    Springer
    Marine biology 76 (1983), S. 325-332 
    Details
    ISSN: 1432-1793
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Oxygen consumption rates of the deep-sea fish Sebastolobus altivelis were measured in situ on pelagic juveniles at mesopelagic depths (608 m) and on demersal adults at bathyal depths (1 300 m) in the Santa Catalina Basin in March 1982. Two pelagic juveniles were individually collected, and respiration was measured continuously for approximately 2 d with a slurp gun respirometer manipulated from the submersible “Alvin”. Oxygen consumption rates of these juveniles were highly variable and were 1.5 to 1.8 times higher during the night than during the day. Gut contents of the juveniles were mainly euphausiids (Euphausia pacifica and Nematoscelis difficilis). Four demersal adults were collected by “Alvin” and individually placed in fish-trap respirometers on the bottom where respiration was measured continuously for approximately 1 d. Weight-specific O2 consumption rates for adults decreased with increasing body weight and were consistent in magnitude throughout the incubation period. Population O2 consumption for demersal S. altivelis (calculated from abundance, size-frequency distribution, and O2 consumption regression equation) was 11.01 μl O2 m-2 h-1, which is two orders of magnitude less than the O2 consumption rate for the population of the most abundant epibenthic megafaunal species in the Santa Catalina Basin, the ophiuroid Ophiophthalmus normani. O. normani is a principal prey for adults of S. altivelis based on gutcontent analysis. Given the population O2 consumption rate as an estimate of food energy demand, the demersal population of S. altivelis would assimilate only 0.007% of the standing crop of O. normani per day.

    Scavenging deep-sea amphipods: Effects of food odor on oxygen consumption and a proposed metabolic strategy (1982)
    Springer
    Marine biology 68 (1982), S. 287-298 
    Details
    ISSN: 1432-1793
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract In situ respiration rates as a response to the odor of food were measured for two species of scavenging amphipods, Paralicella caperesca from 3 650 m in the western North Atlantic Ocean and Orchomene sp. B from 1 300 m in the Santa Catalina Basin off southern California (USA). In addition, complementary laboratory starvation/respiration rates for a shallow-water species, Orchomene sp. A, were determined. Initial elevated O2 consumption rates were found for up to 8 h in all deep-sea amphipods exposed to bait odor, followed by a period of lowered respiration equivalent to rates observed in individuals not exposed to bait. Orchomene sp. A revealed a response similar to that observed in the deep-sea species. A metabolic strategy is proposed whereby scavenging amphipods efficiently utilize large episodic organic falls in the food-limited environment of the deep sea. This strategy involves (1) the ability to withstand long periods of starvation, (2) rapid response to an organic fall, (3) rapid location of the organic fall, (4) maximal rate of food consumption with maximal quantity ingested, and (5) efficient utilization of the consumed food. Each of these attributes are explored with the expected and observed mechanisms employed to achieve them.

    Metabolism of two dominant epibenthic echinoderms measured at bathyal depths in the Santa Catalina Basin (1983)
    Springer
    Marine biology 72 (1983), S. 249-256

    Topics: Biology
    Notes: Abstract Metabolism of two abundant echinoderm species constituting 99.6% of the epibenthic megafauna in the Santa Catalina Basin, off southern California, USA was measured at 1 300 m during the 1979 “Bathyal Expedition”. Specimens of the ophiuroid Ophiophthalmus normani and the holothurian Scotoplanes globosa, collected by the submersible “Alvin”, were individually placed in respirometers, and measured in situ for O2 consumption and ammonium excretion rates. For O. normani, weight-specific O2 consumption rates decreased with increasing weight and were of comparable magnitude to rates of deep-sea and shallow-water ophiuroids; excretion rates were highly variable. Population O2 consumption and excretion rates for O. normani (estimated from size-frequency distribution, abundance, and rate regression equations) were 1 129.28 μl O2 m-2 h-1 and 27.30 nmol NH 4 + m-2 h-1. Weight-specific O2 consumption and ammonium excretion rates of S. globosa decreased with increasing weight and were of comparable magnitude to rases of shallow-water holothurians. Population O2 constimption and excretion rates of S. globosa were 1.38 μl O2 m-2 h-1 and 4.86 nmol NH 4 + m-2 h-1. Combined population O2 consumption rates for O. normani and S. globosa are of comparable magnitude to that of the sediment community and plankton in the benthic boundary layer (sediment and overlying 50 m water column) of the Santa Catalina Basin.

    Evaluation of A Modified Gradient Feed Culturing System for Growth of Lactobacillus plantarum Sausage Starter Organism (1983)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 48 (1983), S. 0

    Notes: An internally controlled gradient feed culturing technique, where a nutrient gradient was initiated and subsequently controlled by the lactic acid synthesis, was compared to conventional batch culturing for growth of a sausage starter organism, Lactobacillus plantarum. Significantly higher cell densities (p 〈 0.01) were observed with twice the culturing time for gradient feed culturing compared to batch culturing. Cell yields within batch or gradient feed culturing system were not affected by pH control at 5.8 or 6.0. Significantly higher (p 〈 0.05) cell yields, however, were obtained for gradient feed cultures (pH 6.0) with NH4OH addition at 50% theoretical lactic acid (TLA) level than were obtained at 10% TLA or without NH4OH addition.

    Temperature Histories in a UHT Indirect Heat Exchanger (1984)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 49 (1984), S. 0

    Notes: An indirect UHT processing system was modeled by a computer program to predict the temperature profile of a mass element of fluid as it progressed through heating, hold and cooling units. The computer program consisted of successive calculations of the temperature at the exit of numerous increments in each unit based on the overall heat transfer coefficient determined for the total length of the unit. The validity of the computer program was determined by correlation of computer results with experimental determinations of sucrose inversion. The percentage of total inversion of sucrose occurring in the heater was 36%, indicating the error associated with the assumption of chemical reactions based exclusively on hold tube temperature, residence time and laminar flow pattern.
