“…The present study results could be explained by the biocontrol agents using different routes of lactose utilization from the culture medium. It has also been reported that incorporation of lactose in bioformulations can favor stability and survival of T. harzianum over a wide range of storage temperatures (-20 to 30°C; Kumar et al, 2016), since lactose protects against desiccation, stabilizes proteins and lipids in cell membranes (Santos et al, 2011), or can be a prebiotic (Chávez and Ledeboer, 2007). Talc, although showing no effects on mycelium growth of C. rosea or T. harzianum, decreased the conidium germination of T. harzianum, probably because this substance can form barriers surrounding conidia, reducing the water and nutrient, and germination of the conidia (IARC, 2010).…”

“…These include compounds that do not affect the environment due to their short or null persistence, and include lactose, inulin, talc, or maltodextrin, among others (Wilkins, 1990). Use of lactose can improve survival of T. harzianum during storage (Kumar et al, 2016), and inulin protects T. harzianum viability against freez-ing and freeze drying (Mensink et al, 2015;Nunes et al, 2018). Maltodextrin has been used to extend bioformulation shelf-life after production using the spray drying technology (Leslie et al, 1995;Agudelo et al, 2017), and talc has been used as a carrier additive for solid formulations containing Trichoderma spp.…”

Grapevine trunk diseases (GTDs) can cause large losses in vineyards. Diplodia seriata is an important GTD pathogen in Chile. Development and use of bioprotectors is a complementary alternative to the use of agrochemicals for disease management. To produce bioformulations for management of D. seriata, additives could be used to maintain viability and survival of biocontrol agents, such as Trichoderma harzianum and Clonostachys rosea. Effects of drying supports (inulin, maltodextrin, lactose, or talc) and adhesive polymers (carboxymethylcellulose, Aloe vera gel, or chitosan) were assessed on D. seriata conidium viability and mycelium development of T. harzianum and C. rosea, and for their biocontrol capacity against D. seriata. T. harzianum and C. rosea cultured in Potato Dextrose Agar containing inulin (at 10% w/v) maltodextrin (10% w/v), lactose (6% w/v), or talc (4% w/v), or the adhesive polymers carboxymethylcellulose (0.5% w/v), Aloe vera gel (0.5% w/v), or chitosan (1.5% w/v), maintained their biocontrol activity against D. seriata. These additives did not enhance D. seriata development. Therefore, these preparations, at the respective indicated concentrations, can be included in bioformulations for management of disease caused by this pathogen.

“…They have easy synthetic processes and coordinate with a broad spectrum of metal ions to form related metal complexes. In addition of coordination chemistry, these compounds have large potential applications in other fields of science and technology such as catalysis area, medicine, optical industries, bioinorganic chemistry, polymer industries, and microbiological utilities [5][6][7][8][9]. The role of Schiff base complexes in the biological field is especially of interest.…”

A series of novel five coordinated mercury(II) complexes of a new recently synthesized tridentate ligand are presented. The mercury(II) complexes were characterized by various spectral and physical techniques such as FTIR, UV-visible, 1 H and 13 C NMR spectra, thermal analyses, and decomposition temperature and conductivity measurement. Also nanostructure size of titled mercury coordination compounds have been prepared by the reaction of ligand and mercury salts under ultrasonic conditions. The nanostructure size of the complexes was confirmed by XRD patterns, scanning electron microscopy, and transmission electron microscopy. According to the mentioned analyses, the molecular formula of HgLX 2 (X = halide and/or pseudo-halide anions and L = ligand) was suggested for the complexes. Thereafter all mercury(II) complexes were tested for their in vitro antibacterial activities against two Gram-positive (Staphylococcus aureus and Bacillus subtilis) and two Gram-negative (Escherichia coli and Pseudomonas aeruginosa) bacterial strains. Also in vitro antifungal activities of them against Candida albicans and Aspergillus niger were investigated. The results indicated that all compounds can act as antibacterial and antifungal agents. Moreover, thermal behaviors of the complexes were studied in the range of 20-900°C. Thermogravimetric study indicated that the mercury complexes are thermally degraded via 3-9 thermal steps.
