“…Valdez et al [71] treated sunflower seeds with B. subtilis for investigating its effect on plant growth, soil properties and greenhouse gases emission while using urea as positive control for comparison. The results showed that after one month, root length and root-shoot fresh and dry weight were considerably higher than ureatreated plants.…”

Plant pathogens are the main threat for profitable agricultural productivity. Currently, chemicalbased pesticides are thought to be an effective and reliable agricultural management measure for controlling pests. Chemical pesticides are highly effective and convenient to use but they are a potential threat for the environment and all kinds of life on earth. Therefore, the use of biological control agents for the management of plant pathogens is considered as a safer and sustainable strategy for safe and profitable agricultural productivity. Bacillus-based biocontrol agents play a fundamental role in the field of biopesticides. Many Bacillus species have proved to be effective against a broad range of plant pathogens. They have been reported as plant growth promoter, systemic resistance inducer, and used for production of a broad range of antimicrobial compounds (lipopeptides, antibiotics and enzymes) and competitors for growth factors (space and nutrients) with other pathogenic microorganisms through colonization. The aim of this article is to present the biocontrol potential of Bacillus species in relation with their antagonizing attributes against plant pathogens. These attributes include production of lipopeptides, antibiotics and enzymes as well as plant growth promotion and systemic induced resistance.

“…Similarly, elicitation was not peculiar to those bacterial species closely related to the formation of "blooms" by the green microalgae, but instead also was seen with B. subtilis which is not related in the same way to the microalgae. This lack of specificity in growth promoting activity could be caused by the previously reported growth inducing capacity of plants by B. subtilis (Zablotowicz et al 1991), achieved by various strategies, including the production of phytohormones, especially of the type auxin IAA and gibberellins as AG3 (Chowdappa et al 2013, López-Valdez et al 2011.…”

There are several strategies to improve the growth of microalgae in industrial processes. In recent years, one of them has gained strength to achieve this goal: the co-culture with bacteria. Using growth-promoting substances, producer bacteria enhance microalgae biology activity, similar to how they have been used to promote the successful production of crops. The aim of this study was to evaluate the promoter capacity of strains Bacillus subtilis, Corynebacterium aquatile and Flavobacterium aquatile, evaluate their ability to improve the growth rate of microalgae Botryococcus braunii and to optimize the process derived from its cultivation. This study showed that the tested bacteria were able to increase up to 1.7 times the B. braunii growth rate and this promoting ability remained present in cell lysate preparations from the same bacterial strains. Key words: Botryococcus braunii, Flavobacterium aquatile, Corynobacterium aquatile, Bacillus subtilis, microbial elicitation, co-cultivation ResumenEl empleo de bacterias productoras de sustancias promotoras de crecimiento, para mejorar la eficiencia en el crecimiento de las microalgas y así potenciar su actividad en procesos industriales es una práctica que ha tomado fuerza durante los últimos años, de manera análoga a como han sido utilizadas las bacterias para favorecer la producción exitosa de cultivos vegetales. El objetivo de este trabajo fue evaluar la capacidad de las cepas Flavobacterium aquatile, Corynobacterium aquatile y Bacillus subtilis de actuar como promotoras en el crecimiento de la microalga Botryococcus braunii con el fin de mejorar su velocidad de crecimiento y optimizar los procesos derivados de su cultivo. Este estudio muestra que las bacterias evaluadas tienen la capacidad de aumentar hasta 1,7 veces el crecimiento de B. braunii y esta capacidad promotora continúa presente en preparaciones de lisados celulares procedentes de estas mismas cepas bacterianas.

“…From the beginning of the experiments and approximately every two days for the following 30 days, the pots were closed air-tight and their atmosphere was analysed for CO 2 and N 2 O at times of 0, 3, 15 and 30 mins. The experiment was repeated twice [6].…”

“…As previously discussed, wastewater sludge is an organic matter which is rich in easily decomposable material. In addition, it has been demonstrated that microorganisms from the sludge plus those from the soil work together synergistically to accelerate the decomposition of organic matter [6]. The high levels of microbial activity stimulated by the addition of material with high C and N contents could increase the production of both CO 2 and N 2 O.…”

Greenhouse Gases

Greenhouse gases, such as carbon dioxide CO , nitrous oxide N O and methane CH , play an important role in global climate change. For example, CO production occurs as a result of the seasonal cycles of the biotic processes of photosynthesis and respiration, as well as through anthropogenic activities and abiotic processes such as the burning of fossil fuels. Many activities, such as "gribusiness the production of crops and animals for food create greenhouse gases. Our research group has studied several soil treatments such as wastewater, wastewater sludge, vermicomposting, and urea among others, in order to study the effects of soil treatments on the production of greenhouse gases CO , N O, and CH in several cultivars, but mainly in maize, sunflower and the common bean. The principal aim of this chapter is to show how these greenhouse gases are affected by the type of treatment, the properties of the soil, and the cultivar in question. We also look at which processes are involved in the production of CO , N O, and CH from cultivated soil. We present a review of several experiments carried out under in vitro or greenhouse conditions.
