DOI: 10.1002/biot.70009
Abstract: Isoamylase (IA), a starch debranching enzyme that cleaves α‐1,6‐d‐glycosidic bonds in amylose, is used in various industries. However, its low expression in Escherichia coli BL21 (DE3) limits its application, necessitating fermentation optimization. Limiting carbon (C)… read more here.

Stoichiometry and daily rhythms: experimental evidence shows nutrient limitation decouples N uptake from photosynthesis.

DOI: 10.1002/ecy.2822
Abstract: Diel variability in nutrient concentrations is common but not universal in aquatic ecosystems. Theoretical models of photoautotrophic systems attribute the absence of diel uptake variation to nutrient scarcity, such that diel variability in nutrient uptake… read more here.

Leaf NPK stoichiometry, δ15 N, and apparent nutrient limitation of co-occurring carnivorous vs. noncarnivorous plants.

DOI: 10.1002/ecy.3825
Abstract: Previous meta-analyses suggested that carnivorous plants - despite access to N, P, and K from prey - have significantly lower leaf concentrations of these nutrients than non-carnivores. Those studies, however, largely compared carnivores in nutrient-poor… read more here.

DOI: 10.1007/s11104-017-3473-9
Abstract: AimsThe changes of nutrient limitation status for tree growth across a plantation chronosequence have great implications for plantation management. The underlying mechanisms for such a shift, however, have seldom been addressed. While plant nutrient use… read more here.

DOI: 10.1080/20442041.2024.2442210
Abstract: ABSTRACT Studies of algal growth responses to nutrient availability at the catchment scale are sparse. Here we study algal nutrient responses in headwater streams, rivers, lakes, and an estuary in a temperate coastal catchment. Nutrient… read more here.

Enhancing sn-2 specific Fatty Acid Accumulation in Microalgae: Impact of Nutrient Limitation on Structured Triacylglycerol Profiles
Sign Up to like & getrecommendations! Published in 2025 at "International Journal of Food Science and Technology"
DOI: 10.1093/ijfood/vvaf200
Abstract: The production of structured triacylglycerols (STAGs enriched in sn-2 specific fatty acids were examined for the microalgae Chlamydomonas reinhardtii, Scenedesmus obliquus, Nannochloropsis oceanica, and Nannochloropsis oculata. The objective was to explore the effects of varied… read more here.

DOI: 10.1099/mic.0.001316
Abstract: In Pseudomonas aeruginosa , quorum sensing (QS) depends on an interconnected regulatory hierarchy involving the Las, Rhl and Pqs systems, which are collectively responsible for the co-ordinated synthesis of a diverse repertoire of N-acylhomoserine lactones… read more here.

DOI: 10.1111/1365-2745.12823
Abstract: Potential variability in nutrient limitation among tree size classes, functional groups and species calls for an integrated community- and ecosystem-level perspective of lowland tropical rainforest nutrient limitation. In particular, canopy trees determine ecosystem nutrient conditions,… read more here.

Nutrient limitation or home field advantage: Does microbial community adaptation overcome nutrient limitation of litter decomposition in a tropical peatland?

DOI: 10.1111/1365-2745.12923
Abstract: Litter decomposition is an important control on carbon accumulation in tropical peatlands. Stoichiometric theory suggests that decomposition is regulated by elemental ratios in litter while the home field advantage (HFA) hypothesis predicts that decomposer communities… read more here.

DOI: 10.1111/brv.12524
Abstract: Theory predicts that costly sexual traits should be reduced when individuals are in poor condition (i.e. traits should exhibit condition‐dependent expression). It is therefore widely expected that male ejaculate traits, such as sperm and seminal… read more here.
