Temporal variation of total carbohydrates, polysaccharides, monosaccharides and microbial metabolic activity in Estero de Punta Banda, Mexico

Temporal variation of total carbohydrates, polysaccharides, monosaccharides and microbial metabolic activity in Estero de Punta Banda, Mexico

The concentration of total carbohydrates (CHOT), monosaccharides (MCHO) and polysaccharides (PCHO) was measured in situ using the MBTH technique. Samples were taken in diel cycles inside and outside a mesocosm in order to elucidate the pattern of production and consumption. Six seasonal samplings we...

description The concentration of total carbohydrates (CHOT), monosaccharides (MCHO) and polysaccharides (PCHO) was measured in situ using the MBTH technique. Samples were taken in diel cycles inside and outside a mesocosm in order to elucidate the pattern of production and consumption. Six seasonal samplings were conducted in one year during spring tides. Changes in the different carbohydrate fractions were compared to temperature, chlorophyll a, dissolved oxygen, gross production bacterial biomass and planktonic community respiration. Outside the mesocosm, the changes in these variables are mainly intluenced by advective processes. A linear, inverse relationship between PCHO and MCHO is found, suggesting microbial degradation. Also, CHOT concentrations ate directly proportional to PCHO concentrations. The variability of the MCHO concentration is mainly esplained by chlorophyll a, suggesting a phytoplanktonic origin. On the other hand, PCHO are mainly explained by the tide and temperature. indicating their possible origin in the macrophytes of the marsh area. The presence of carbohydrate-like organic matter is detected by the MBTH technique masking the diurnal variations of- the carbohydrates outside the mesocosm. Outside the mesocosm, advective processes interfere with the interpretation of diel cycles of the MCHO, PCHO, and CHOT concentrations. However, inside the mesocosm it is possible to clearly observe carbohydrate degrading processes on a seasonal scale.

La concentración de carbohidratos totales (CHOT), monosacáridos (MCHO) y polisacáridos (PCHO) se midió mediante la técnica del MBTH en ciclos diurnos in situ dentro y fuera de un mesocosmos con objeto de elucidar sus patrones de producción y degradación. Se realizaron un total de seis muestreos estacionales durante un año y en mareas vivas. La variación en la concentración de las diferentes fracciones de carbohidratos fue comparada con la temperatura, clorofila a, oxígeno disuelto, producción bruta, respiración de la comunidad planctónica y biomasa bacteriana. Los cambios de estas variables fuera del mesocosmos son influenciados principalmente por los procesos advectivos. Existe una relación lineal e inversa entre la concentración de PCHO y MCHO que sugiere degradación microbiana. Asimismo, la concentración de CHOT es directamente proporcional a la de PCHO. Las variaciones en concentración de MCHO son explicadas principalmente por la concentración de clorofila a, sugiriendo su producción por el fitoplancton. Por otra parte, la concentración de PCHO es explicada principalmente por la marea y la temperatura, lo cual sugiere que su origen son las macrofitas de la marisma de la laguna costera. La presencia de material orgánico tipo carbohidrato que reacciona con la técnica del MBTH enmascara la variación diurna en la concentración de carbohidratos y los procesos advectivos causan confusión en la interpretación de la concentración de MCHO, PCHO y CHOT fuera del mesocosmos. Sin embargo, dentro del mesocosmos, es posible distinguir claramente los procesos de degradación de carbohidratos en la escala estacional.
