Biomass Estimation Of Marine Biofilms On Plastic Surfaces, Kian Banihashemi, Fernando Javier Gil
Biological Sciences
Plastics have become a major source of marine pollution, which threatens food safety and quality, human health, and marine ecosystems. Due to the drastic negative effects of plastics in a marine environment, alternative biodegradable plastics are being generated that are more eco-friendly and have less environmental impact. Though some of these plastics are known to biodegrade, the process of degradation for bioplastics has not been heavily studied in a marine environment. This pilot project sought to both quantify the process of biodegradation and compare across different methods for effectiveness of biomass estimation, which serves as an indicator of biodegradation. Plastics …

Following an action potential in the presynaptic neuron there is evoked release of neurotransmitter into the synapse which activates ionotropic transmembrane receptors on the postsynaptic membrane that cause depolarizations in voltage that get recorded as excitatory postsynaptic potentials (EPSPs). In the absence of an action potential there is spontaneous release of neurotransmitter that postsynaptically gets recorded as miniature excitatory postsynaptic potentials (mEPSPs). According to the quantal hypothesis, postulated by Bernard Katz, the mEPSPs are allor- none changes in potential caused by a single quantum of neurotransmitter, which when added up create EPSPs. Following studies have found that these two modes …
